MITCHELL B-25J WWII Bomber

[LAMAHORSE]

Welcome,

This will be the Built Thread on the MITCHELL B-25J WWII Bomber.

This MITCHELL B-25J Bomber project will be acheived with a electric powerplant system with the use of Robart super scale retractable landing gears and strut's and also many scale detail's will be acheived and add to it for the next coming months while on the built bench.

Looks like a well built ARF kit.
Should be an interesting build.

[Burning Head]

Yap, a great machine:). nice pic Serge

[Hadi]

Wow it’s a great model, I’m so jealous

[LAMAHORSE]

Shure is,
a great scale project for anyone who as interest in WWII Warbirds.
I'll be going very slow on the making with that Mitchell to created it as a master piece by summer 2011 and to be then flown as a scale flying Bomber at my flying club.

Like my Buddy Paul was telling me at the club yesterday,
we have a great flying field for a B-25J Mitchell to fly off and land as scale view at MRCC with all our natural serunding. Will be very cool for me by next year to have such a flying WWII machine to fly off there ...

[zorba]

Nice plane Serge, Don't tell me that this one will take a year to do? Like the Lama?

Too long man. you can do it in a month..
Cheers

Nice plane Serge, Don't tell me that this one will take a year to do? Like the Lama?

Too long man. you can do it in a month..
Cheers

:D:D:D,,, yea oncle Bill,
It will take all that times ,,, lol ...

But look at the LAMA results,, :D
it took that long and what a wonderfull machine final result's.
On the count of the answers of 3 Master builder's I know, they all came
with the same answer, take your time on it,, as I mention what
I had just got my self for a fully scale project ...

Yea,
it could be done in a breeze,, I agree with yea Bill,
but who's in a rush in this hobby??? Not me ...

The result's at the end of my work are speaking by them self.
Taking our time is only making this great hobby a more pleasante experiences in my life ... But I am shure appreciate the talented buddy Paul while I do create a flying machine. He is a deep sources of help and inspiration while I build a project such as this one ...

Thanks to my buddy Paul,
With you not far, projects are a breeze to acheive ...
Thanks Buddy !!!

[LAMAHORSE]

As the
weather remaining crapy to do any flying,

I have decided yesterday to prepare the house basement corner
built bench to be ready soon as late fall full scale build of my Mitchell.

Last night I have got out one wing of the kit box to inspect and to
view the parts I will be working on for that future project. Slowly reading the manual and slowly checking the parts will be on my menu till I finaly start to built it later on ...

I shure hope that fall as better days to offer me to fly ...
I will shure make my self available for Paul vacation that should be here in Oct month. Then after those vacation, it will be November and that should be a great time to begin my long winter time in the basement and working on a fantastic oldtimer WWII Pacific/Europe war Bomber ...

[LAMAHORSE]

Since last sunday,
it was grey and rainy overcast and I have decided to start to test the parts
into the proper location to see if all fit well on the Mitchell till build thread start very soon ...

Got the B-25J Mitchell fuselage on the build bench table and made a proper stand (made of foam) so it hold & stand above the table & no scratch are to be done at underbelly location with that devise holding the Mitchell. Then I did attach the 2 wings together and got it hold together and attach to the fuse and lock that wing there for proper check and alignment.

Then later got the tail elevator stab on for a test and the fit & alignment was right on track too.

Yesterday,
did start on the engin's nacelle and cowl test & fit. Did try my wonderfull and great looking Robart air retractable gear with scale strut's in there to see the way they are suppose to be inplant. Wow, it looks so good with those scale RG on.

I'm at testing parts and see how they fit together at the moment with this Full scale Mitchell bomber project and I can tell you it is superb and a big aircraft bomber in my house basement for shure to be built in the coming months to come.

I will have a ball that's for shure with that project as it all looking good till now.
More check parts pre-build will be acheived in the next fiew days to come and as soon
as all my check have been done properly,, I will start on it till next summer year.

That will shure keep me very busy ...
Photographies set plates of my build will be shown here soon !

[LAMAHORSE]

It's december already !

The Mitchell as gone to a other location in my hangar Officer mess.
Located on the East Wing hangar side now to have a close parts review check
befort starting the project.

As the West Wing hangar side location as a Hornet in for the making.

This week if all goes well,
I should be able to begin on the Mitchell ...

Scale details and making Informations search are on the menu since a fiew weeks and alote of reading to do ...

[LAMAHORSE]

THE MITCHELL B-25J BOMBER IS ON THE START NOW

Yesterday,
Got all the Mitchell B-25J a parts & back in her proper box and kept only the fuse to start on.

Was suppose to start yesterday,
but as I was seatting down to get going the door bell ring. It was my
Mom sister of 84 coming in for the holidays share visite and got my self
some gooddies for my tommy. How can I refuse ...

Today if all goes as plan,

I will start inside the fuse by applying glue (Automative contact adhesive and sealant) and silicone in the hard to reach area on the hole inside fuse ribes & balsa join's. That process is to make shure all ribes & join's are well done & proper glue fix as ARF need that special attention just to be shure all are secure and well done in there.

Little will be apply inside, just to make shure all is tight fix and well glue.


Well that's a start ...

[LAMAHORSE]

First process,

on the build as been started and did finish to re-enforce with the first part I have started with.

http://lh4.ggpht.com/_VmYRAkGRDhw/TRMdjhMOf_I/AAAAAAAACgc/LuBfj5fE7io/s512/Picture%20174.jpg


The under-wing center cover bay with the interior view rib's & join's that as been done and complet with glue (Automative contact adhesive and sealant)
and apply with a small amount of glue with the use of a small brush to make it flush and clean.

http://lh3.ggpht.com/_VmYRAkGRDhw/TRMdskE1UPI/AAAAAAAACgg/-jLsHzNnMyw/s512/Picture%20175.jpg

http://lh6.ggpht.com/_VmYRAkGRDhw/TRMd1_efQBI/AAAAAAAACgk/s_AkSaYEIvo/s512/Picture%20176.jpg


Next step will be,

the interior fuse with the same process on the rib's & join's that will be glue
with (Automative contact adhesive and sealant) for the easy acces section and the silocone glue for the far more out of reach section area in there.

[PaulG-rc]

Good stuff Serge

The areas to re-enforce the formers wood to wood can be done with white glue only.
The area where its wood to fiberglass then you use the other products.

[Kevin Rochon]

the more glue you add the more weight the more weight the stronger the impact if you have a mishap.

My ARF Cap 232 has probably more than 2000 flights with some rough landings and 1 crash and if I wouldn't wanted a new airplane it could still fly and I only fixed what needed to be fixed over the years.

The only stress points on airplane, and yours is not even an aerobatic plane so just scale flights, is the spar and the connection between fuselage and tail and the landing gear when landing.

The lesson only fix what looks not right, heavy airplanes don't fly well and are hard to land (high stall speed) especially in the RC world.


Kevin
my 2 cents

[LAMAHORSE]

Thanks guy's,
for your comments and advises ...

I'll make shure to do small application, as i did for the underwing cover bay.

[LAMAHORSE]

Work to,

re-enforce rib's and join's in the fuse is still on the go ...

While glue cure,
took the time to see what will come ahead soon on the nacelles issue.
Got to test the amazing Robart scale main retractable gears with those superb strut's in their proper location.

Also,
Here is a outlook of a color scheme that I would really like on my B-25J Mitchell to come up with in a near future if I ever go for such idea. At the moment it still to early, but that one color scheme and that idea shure keep's coming back in my mind ... Maybe by next year ... Will see ...

http://lh3.ggpht.com/_VmYRAkGRDhw/TRXDCck8k9I/AAAAAAAAChk/5HG7pzfv_LM/s512/Picture%20177.jpg

[LAMAHORSE]

Today,

will continue the fuse glue re-enforce process at rib's and join's.
Small amount of glue with that mind set will be apply so to keep the weight down and to keep the rib's and join's well secured.

That will be done easely in there with the Lepage white glue.
If all goes well I should have complet the fuse glue process by today's end ...

[LAMAHORSE]

The process,
with Lepage glue application with rib's & join's continued.

The under front fuse nose gear bay door hatch as been open to acces
the nose section as to apply the Lepage glue application in there ...

B-25J Mitchell,
nose gear bay door hatch opening:

[LAMAHORSE]

Did some more
on the fuse yesterday.

The nose front section (RX batts) as been re-enforce with the application
of Lepage white glue around rib's and join's.

http://lh3.ggpht.com/_VmYRAkGRDhw/TRxU_d5BwtI/AAAAAAAACi8/f18kjlCK9s4/s512/Picture%20511a.jpg

Then next was to do the front retractable gear bay area. Befort going in
I wanted to test the nose gear in to see the proper fitting location. As I don't
want to apply glue over area where I will inplant the retract's holddown point metal plates of the devise.

http://lh6.ggpht.com/_VmYRAkGRDhw/TRxVG4giB1I/AAAAAAAACjA/QbGKq1OvfRg/s512/Picture%20513a.jpg

Was going to start to apply the Lepage glue and what do you expect,
Holidays famely visitor's showed-up at my door for a day visite.

What do expect in the xmas holidays season,, Visitors what else ... ;D

Today will do some more work in there ...

[LAMAHORSE]

Time to choose,
my electric powerplant engin's motors!

The BL46 outrunner electric motor,
are the engin's that as been test & design for this model and are sold with the Mitchell if you wish to go electric powerplant. I will follow the same route as many did and have choose the BL46 for is reliability and quality that I am looking for in a twin aircraft like this one.

I have not decide what will be the ESC I will get yet. The 60A ESC is the one they sale with the 46BL but I mite just go for the 80A just to be shure and it depend on the Lipo's batteries I will get to power that beast bomber. Will have a talk with my scale mentor buddy by this week-end and will have the answer to that by next week and will then purchase order the best ESC and Lipo's for it.

But the Lipo's mite come later on the purchase order ...
I have not made up my mind on what brand Lipo's & size will be choosing.


Yesterday,

Did finish the front nose retractable gear bay door area section with Lepage glue and apply with a brush and the servo bay are located right behind the RG bay door area and as been done also.

All rib's and join's have been done and did apply small amount of Lepage glue in there just to be secure and with the brush it makes it easy to have a clean application to all specific area zone.

http://lh3.ggpht.com/_VmYRAkGRDhw/TR2o_CehgJI/AAAAAAAACjc/9YTvmX3XTC8/s720/Picture%20518.jpg


I will have to see about the nose gear attachment section. As I did read on many thread build that it would be good to re-enforce some parts in there as it seem weak at time from the factory and not anought secure holddown blocks in there for the retract's to be well secure.

Again will have to see what will be add in there to make it more secure for the nose gear befort inplant the retractable gear in a soon future.

http://lh3.ggpht.com/_VmYRAkGRDhw/TR2pHFU1EXI/AAAAAAAACjg/tOdBW4m_NMw/s512/Picture%20519.jpg


The fuse with Lepage glue application on rib's and join's continue !

[bob forest]

Lamahorse, your pictures are incredible. Really nice and clear. Did you weigh the plane before you aplied the white glue. It would of been interesting to see what it weighed before and after. Also you might have to add some strenghning blocs for the retracts. I have a feeling with this plane you have a lot of room re weight added as it is a large wing. But would of been curious to know the weight difference. Looking forward to seein this plane in the air.
All the best to you Serge for the New Year, and good Health to you.
Bob:)

[Mick]

Lamahorse, the BL46 is an excellent, high quality motor. I use one in my Hanger 9 Piper Pawnee 40. I use a Turnigy Plush 60 ESC and a 4S 5000mAh battery driving a 14x7 prop. Performance and duration are very good. The standard recommended prop is 13x8 but the Pawnee fuselarge is very big so I want a bigger diameter prop, with a twin you will not need this. I would recommend you stay with the standard set-up, it works well. I have tried other motor & prop set-ups and nearly lost the aircraft. The take-off current draw from the BL46 should not exceed 50A, it does not need an 80A ESC. Save the money and weight.

As it will be a beautiful aircraft I would also recommend an in-flight battery monitor:

http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=10343

It gives great peace of mind and provides all the warning time you need for a good landing if the batteries are fading, you will only need one as the advantage of electric is consistency and reliability.

As always you are doing a great build, look forward to seeing it in the air.

[LAMAHORSE]

Good day,
Oncle Bob and Mike ...

A good year to yea too Bob and to your lovely wife with good health with alote of good time and many great flights to come.

And no I have not weigh the Mitchell.

It wont make much differences in the weight with the Lepage application
I am doing. Very small amount is apply just to secure everything and all as been clean silk as I do it with the brush. But I do agree with yea, it would have been fun to know the weigh befort and after.

It's a large model and the little I did in there, the Mitchell can take it ...

And thanks for the input Mike ...
I will see to this for shure, as you have said, it is a wonderfull model and I'll do on the Mitchell what need to be done right. As it were the full scale real life size bomber.

Glade I have my buddy Paul around while I build ...
A mentor like him is what every guy like me need to succed while building a scale project.

Thanks guy for input and feel free to comments my work.
I do appreciate this very much ...

Yesterday,

did more on the fuse Lepage application. I am in the Mid-section tail right now and it is a slow process as there is little space to work around the rib's and join in there. So today I will do some more in the morning and hope maybe I can finish that route by today befort the famely arrive.

Slow build is the key to succesful aircrafts result.
I'll stay with that input for my part ... :D

[LAMAHORSE]

Well,

the fuselage with Lepage application on rib's and join's as been final complet yesterday afternoon.
It was a long ron on that process, but it look very secure now and well done.

Mitchell Fuse
with Lepage rib's & join's application complet now:

http://lh6.ggpht.com/_VmYRAkGRDhw/TSGgJsA2tEI/AAAAAAAACkE/_hf6cV_FxsQ/s720/Picture%20522.jpg


Next is to secure,
with automative Goop glue all rib's and join's in there in the nacelles as well.

http://lh5.ggpht.com/_VmYRAkGRDhw/TSGgPete1cI/AAAAAAAACkI/Ep-beohyZx8/s720/Picture%20523.jpg


Now,
about the powerplant system use. I have spoke to my mentor in scale making yesterday. We spoke about all options as I wanted to be shure with him for my best route with the Mitchell.

http://lh6.ggpht.com/_VmYRAkGRDhw/TSGgXr1-YrI/AAAAAAAACkM/c0E8gnjk_-Y/s512/Picture%20528.jpg


I will probably go with the Mitchell powerplant set-up that they sale with the B-25 from Horizon.

As it fly great and no major issues with those set-up and fly well and scale too with them on. Not any good reason to go any other way or route as it as made is proof in reliability and performance from the past.

Will be using a 3 blades prop's for each electric motor's engin's with that powerplant set-up from Horizon

Should be doing my order by this week with buddy Pete ...

Well here is what my scale master mentor buddy had to say about the 3 blader prop's for the Mitchell that I want to use.

For the 3 blades in black the Master Airscrew are good.
You would need a 13x6x3 but theydont seem to have electric props in that size.

You might have to go 12x6x3 if using a glow version prop.
Lots of flyers just use the Glow version as they are light props.

12x6x3
http://www.greathobbies.com/productinfo/?prod_id=MAS1260T


Now,
back to the engin's nacelles on the Mitchell ...

[Burning Head]

Serge, if you use a Masterairscrew. Remember to remouve the brake on your speed control with the programing card. those prop are heavy and tuff for ESC to stop . Are you go with a conter rotating systeme on:)

[Mick]

Serge, best get a few different size props and test with a watt meter to ensure you are getting enough power but not too much current before first flight, if you don't have one you can borrow mine it can use either Deans and 4mm bullet connectors.

[PaulG-rc]

Thanks Mick

I got all the stuff to check the power system too.
This one could be tricky as they dont offer much in 3 blade props electric.
It would be better to stay in 2 blades for flight and 3 blades for static but thats not my choice. :)

[Mick]

I agree. I would recommend sticking to the APCe 13x8 two blade for first few flights and then experiment with various 3 blades once you get a feel for the performance.

[Burning Head]

If you pick a 13x8 two blade you will need to going down to a 12x8 on 3 blade prop:cool:

[PaulG-rc]

Not really the same for electric as for glow power it depends on the choice of props. :)

[Burning Head]

Copy Paul, but did he go with conter rotating way:)

[PaulG-rc]

Not there yet :D

[Burning Head]

My BH Mosquito 63" ws is a C.R.P, I expect is maiden fly on sky:cool:for this week end. But that's a other story:D sorry serge:cool:

[LAMAHORSE]

As plan,

I have started the Automative Goop glue on the right ENG (2) nacelle.
Did finish the process to glue the woody rib's and join's via the fiberglass nacelle structure.

http://lh6.ggpht.com/_VmYRAkGRDhw/TSLxjHCDaRI/AAAAAAAACk0/wSNazvDTGNg/s512/Picture%20529.jpg

All look good and only one section as not been glue bond in there on nacelle right ENG (2). The retractable gear block
section area will wait till I make new gear attachement block to make those RG sytem tight point more secure for operation.

http://lh5.ggpht.com/_VmYRAkGRDhw/TSLxrEcSxSI/AAAAAAAACk4/H4_fwSlQigI/s512/Picture%20531.jpg


Today,
will do the same process with automative Goop glue on rib's and join's on the left ENG (1) nacelle.

http://lh5.ggpht.com/_VmYRAkGRDhw/TSLxxr6csvI/AAAAAAAACk8/3erEeyvcIKg/s512/Picture%20534.jpg

[LAMAHORSE]

Thanks Buddies
for the help, advise and offer ...

I appreciate this ...

As I build I will see about the prop's and blades size to have
the best performances. Iwould really like to stick to the 3 bladers
to fly this Mitchell.

Many do and have not seen any bad issues about it on their flight de-briefing.
I guess it just take time to find the proper 3 bladers to roll out this Bomber.

Glade I have got Paul beside me on this one ...
Thanks Buddy !!!

I am also glade you guy's jump in and have insite to say about electric powerplant. It is always nice to see other point of view on the subject.

And BH,
your welcome anytime with any saying on here.

Have a superb MAIDEN with the Mosquito this week-end BH Bud!

[PaulG-rc]

Thats where you have to be careful, its not because others say that have had no issues thats its ok.
Lots of flyers dont even check the specs of their power system and boost power and are slowly killing it. Then comes ...............its a bad system :rolleyes:
You go with what they recommend and then you test properly very carefully if you care about the power system :)

[Kevin Rochon]

I agree with Paul for your first flight you want to be safe specially after all your work so go with the pop that works then when you know everything is ok, let say you have tonnes of power, then you can experience with scale prop(I know it looks better with the 3 blades;))

[LAMAHORSE]

Yesterday,

got to finish the process with automative Goop glue on rib's and join's on the left ENG (1) nacelle. all look good as both ENG (Left ENG 1 & Right ENG 2 ) nacelles have been complet on the re-enforce process.

Been putting together the ENG 1 & ENG 2 nacelles for a test try on the wings.
Did inplant and not glue yet the 2 dowell's in the wing edges to hold down the front of the nacelles to the wings.

http://lh4.ggpht.com/_VmYRAkGRDhw/TSQ-oxukY9I/AAAAAAAAClc/tlGkO1YiqH8/s512/Picture%20537.jpg

[LAMAHORSE]

Electric motor Installation,

is what I have acheived yesterday or at lease a start.

I have got the left ENG nacelle on the bench table and apply
over it the appropriate Left ENG mounting template to drill for
the attach motor standoff. Did use a tube in center hole of the
nacelle and template to keep everything straight.

Then I had tape my motor template to the nacelle and ready for drilling
with a 1/16 on 4 location on that template attach unit.

The 4 locations drill holes have been done and will remove the templates
so I can enlarge the hole with a 5/32 drill size to accept later the ENG standoffs.

https://lh3.googleusercontent.com/_VmYRAkGRDhw/TVZSEwdtXAI/AAAAAAAACnE/I86GaN73eOw/s720/Picture%20568.jpg


The ENG standoffs have been bolt to the firewall now and not tight
fite yet. As I have to let them loose a little to attach the motors x-mount
that will be acheived today with the motor attach to it.

This last,
week-end ,,,

Got going to inplant my both 46 Eflite motor to the standoffs attach to the firewall.
Wow, those small 46 EFlite are really nice little outrunner ...

I have then got the nacelles to the wing location and did inplant them to see how
they will fit. There is 2 dowell's in each front nacelle to hold the front section
and 2 small bolts to hold down the rear of the nacelle to the wing.

The first right side nacelle got on after a fiew try out, as the fitting for the rear small bolts
are not so easy to screw in ,,, not align in some ways and came like that ...
The left nacelle took me 2 hours to install as the rear bolts really gave me some hard time.

My Master builder buddy told me this morning that it is tricky at time to install such a part,
but again I will see if I keep those small bolts to attach the rear nacelles or I get some other kind and a little
biger to screw in easely. Will see what my other buddy that as the hobby store have in stock for me on that issue ...
He knows pretty well Hangar9 products and I am shure he can come up with a greater solution ...

If not ,,, well I'll just keep it that way ...

Also,
was going to fit my Robart RG scale and while I was going foward ready for it,
got to read in the Hangar 9 manual that I will need bolts from the Robart RG scale to attach on to the gear holddown location.

I thought Robart had the hardware bolts in the Kit box of the Robart RG scale I purchase.
NO ,, no bolts to be found in the box ,,, just the gears and the air system hardware that's all.

Is this normal or did they forgot to put them in my box Robart kit?

Will see with my hobby store today ...
I would have love to work on those RG befort any other things while be on the nacelles..

[PaulG-rc]

Unfortunatly Robart didn't forget as it is mention in the manual that they are needed for the robarts gear.
I just find it sad that they design it for the kit and dont even supply the bolts with the package. go figure. :rolleyes:

[LAMAHORSE]

yea Paul,

where that idea come from ...
If you buy a car ,,, does it come with tires attach to the car ?
No sir ,, you'll have to buy them speratly ,,, lol ...


Well got my stuff from Pete ... Bolts and all ...
Built will continued now ...

[LAMAHORSE]

The last fiew,
weeks have been kind of busy but back on the routine
with the Mitchell now ...


To come,

will be to cut the retractable main gears door's bay from under
left and right nacelle. I have align the cutting area with tape.

One of the nacelle seem a little off align from carves line already done from the factory. Will see to cut on the right alignment route so the strut get's in straight into the retract bay area.

Only one seem off ,, so will make shure to cut it where it will do a great job even if I have to be off the already mark carves lines to follow from factory ... Little ajustment at time with ARF ...

Will take my time and all should fit smoothly ...
Yea I will take my time no rush how so ever need to be perfect.
Little by little I'll cut the door's so it come to my satisfaction result.

The Mitchell,

continued on the making of the RG's today.
Drilling holes all day it will be to attach the gears properly
at there respecting holddown point.

Then will do the under "Belly" nacelles opening to get those gears
struts going in the nacelles and make them fully retracted inside.

The last time I was on the Mitchell I had all tape the specific
area to be cut down on the fiberglass and while I was getting
one of the main gears and struts proper position I did see that it
would retract not right and straigh where it would need to be
following those already lines.

So this morning I have check the best position where the RG's
devise mechanic would have to be drill. To find this right position
holddown point I have to cut out first the opening for the wheels to
retracts in the nacelles. So now will go cut those opening (inside the
lines pre-mark) and following with the positioning of the RG's mechanic
devise on the rail's (not drill yet) and test fit the roll retract action by
hand and see if the wheel will clear all.

Then I will mark the 4 holes into where it fit best for that retract action
and will drill them. I will shure go very slow to see everything befort it happen ...

All will go fine,,,
just need to take my time and not rushing anything in there.

Will update soon with photographies on the process I had taken ...

[LAMAHORSE]

Yesterday,

got going on the nacelles underbelly RG's cutting area
where the retract's struts wheel's gears will be store while retracting
action will be activated.

All when pretty go and better then I was expecting.
Will do some more ajustment on the already cut area
so that the RG's get's in nicely.


https://lh3.googleusercontent.com/_VmYRAkGRDhw/TaQaXRX1sqI/AAAAAAAAC-Q/ySGJ0e4LkwM/s720/Picture%20600.jpg


Next will drill 4 holes where the bolts & nut's will be located
in proper position on the rail so the wheels clear greatly the open gears storage bay area.


https://lh4.googleusercontent.com/_VmYRAkGRDhw/TaQaRsG5dVI/AAAAAAAAC-M/cbOb62M7huw/s720/Picture%20595.jpg


Reamin to do also is the front nose retractable gear and open storage bay area ...

[LAMAHORSE]

Yesterday,

got going on the nose gear door bay.
I have the one from the kit it self, but will put that good one
on the side to be use later as I will do maybe next fall or winter
my retractable closing doors and will need that one in one piece.

So made a other door for the front nose gear and will make the hole
so that the gear and strut get's in smoothly. I have sand the wood balsa block
so it can acheive the proper corner's curves around the fuse round bottom.

At the moment waiting to receive proper information
to where to drill my 4 holes to holddown the RG's devises.
Got 2 answers this morning and will read more befort making the
right inplant drilling holes.

Till now, the informations are very accurate and trusty as owners of the
same type Mitchell have done it with succesful result's ...

Will make up my mind and will proceed soon ...


NEW making of the front nose gear door plate:

Updated

photographies to where the Mitchell stand at the moment.
Will continued the process soon after my buddy visiting from USA.

I want him to see it full assemble ...

Got all my wood screw's from hardware store this week-end & will inplant the RG's and will do that process as soon as my buddy visiting as seen it fully assemble for the view it will provide my guess buddy to see ...


Here is a devise that works great to test your RG"s retracting fonction
and to see if they are working well:

While making the photoshooting session,
got a idea while I will do my RG's , it will be to inplant a extra air cylinder
or mechanical solution for to make the front nose RG door bay open and close fonction.

Later in the fall and winter will continue and do my closing
door's for the main RG's to work too ...

[LAMAHORSE]

Yesterday,

when to a friend that as a vertical drill to do my holes in my Wheel's
so to accept the wheel's shaft in there. All when better then i thought
and got a 3/16 drill bite to do the job properly.

The fit was tight with the shaft and that is what i was looking for at first
not over do it the drill holes and make it over size. Then when I got home
I got my hand drill motor machine and drill again straight to enlarge the holes
with the same drill bite of 3/16. Did a fiew pass in there till my shaft were somekind perfect as to fit.

If I would have take the next biger drill bite,, it would have done a over size hole and did instead use the same drill bite to be safer. Glade I did ...

In the coming day's,
working on my RG's fit's and inplant with wood srew's 5/8 size.

[LAMAHORSE]

Yesterday,

did attach the ESC on both nacelles so I have them on for the weight issue later ...


They are on stdby attach now ,, and will fix that to be fix tight later ...

I am also looking to inplant NAV lights and lights system on the Mitchell
and have look in there how open it is to link the lights system cables in there ...


https://lh3.googleusercontent.com/_VmYRAkGRDhw/TbfhPgNhwCI/AAAAAAAADFQ/ptxL-cIIGmg/s512/Picture%20109.jpg


Will be done nicely as it is open in the ribes and alittle have to be drill to acces the wings route.

[Burning Head]

Can I know where is the battery hatch... are you using one or two lipo on:cool:

[Burning Head]

I got it on page 4, sorry serge:)

[MikeRacing95]

I could be off topic but, I like the pictures.
The light is always perfect, the aperture is just reflecting what needs to be clear...
My favorite is the one that you took outside with the blue sky reflecting on the fuselage that matches perfectly with the blue that you have on the tail...
As a fan of both hobbies, pictures and modelism, your thread is always one of my favorite to look at.

[LAMAHORSE]

My pleasure

if you like what you see in here ...
There will be more of those long scale photoshoot shot's soon ...

Thanks for the well going comments, always appreciate those ...


Yesterday,
when to my buddy hardware store to get my washer's that will
be going on the wheel's shaft's and in betwen the wheel's and the strut's.

Now for the next fiew,
I will be on the RG's hold down attach point so the RG's works soon.

[LAMAHORSE]

Yesterday,

done the RG's and used 5/8 wood screw's to holddown.
Was very narrow in there to drill and had the use of the Dremel
too as to make the drill bite go all the way into the rail track's.

One main unit as some kind of movement trow from side to side
as something was not tight anought in betwemn metal gear mechanic
and not the metal plates were the srew's are in and hold down tight.

The other main as less movement (side to side) trow when gears are down and lock. Well will look at it again today as to see what makes my one unit main gear to have such larger movement trow side to side then the other main gear.

I am not so worry about that ... it mite be just a ajustment to do
and all will get back fine ... Shure hope so ...

The nose RG was fine to install.
I only had to enlarge the RG metal plate holes so my 5/8 wood screw's
could go in towards the holddown rail's in there. will also later do the
other 4 screw's to attach in front nose wall too ...

I will see to make ajustment on that one main gear retract and all should
look good to continued the other stuff that need to be done ...

Looking good on her main gears down for shure ...

[LAMAHORSE]

After,
looking at the RG's while the Mitchell lay on her back and leg's up,
I see I forgot to figure one thing ,,,their is no air in the system or not connected yet.

I figure,
that is why I have those large side to side movment from my leg's and not tight leg's fit. Soon as I will have the air system in & I am shure this will come to what expected to be ... Air pressure will tight everything in there.

Why I have'nt thought of that earlyer ... lol ..
