Winter Build: Badan Vertigo 2m

[ChrisPol]

Well just got my kit in, going to build a Badan Vertigo 2M this winter, which will be running on a dle-61 with a re2 pipe, hopefully.

[Sempai-mj]

Is the 2m = 2 Meter?

[ChrisPol]

Is the 2m = 2 Meter?

Yep 15lbs 61cc :)

Interesting!! May need a longer runway.

Actually this is a 3d airplane our runway as a lot of wasted space for this type of plane:D

P.S. would be nicer with a Hacker A60 18M electric, no mess no maitenance no bothering the neighbours no pollution ++++:cool:

But very inefficient.... and more expensive for shorter flight times

Gas
- BME58 - 1,180g
- Carl Muller Header - 70g
- ES composite tuned pipe - 123g
- 500mL fuel tank system - 112g
- IBEC ignition kill - 17g
- throttle servo (Savox 1250) - 30g
- 500mL of fuel - 435g
--------------------
Total = 1,967g

Electric
- Hacker A60-18L - 795g
- 135A ESC (Mezon) - 140g
- Castle 12S BEC - 60g
- 12S-5000 batts - 1660g
- Connectors and wiring - 56g
--------------------
Total = 2711g

So full of fuel, the gasser is 744g lighter or 1.64lbs.
Near end of run (no fuel), the gasser is 1100g lighter or 2.42lbs.

interesting weight comparison. How much weight does the electric version lose as the battery runs down?

You will have to get an electron scale...:D

I actually land my 42% in my profile picture in under 50' stopped, trying to figure out how to fit it in my new car Saturday, the rudder does not come off

[Xavier]

I believe you are missing the ignition battery in the list but that should not be very heavy.

However, there is more weight saving possible on the electric version as you have (almost) no vibrations. Motor mount could be lighter, servos could be smaller/lighter, receiver battery could be smaller as the battery consumption is a lot less, ect. Even the structure of the airplane could be made lighter and still last for a long time. It's a complete package to be optimized.

The motor behavior and response is very different too.

In the end it's a personal choice and it's difficult to put numbers to it.

Xavier, you forgot to mention the weight of the speaker necessary for the electric version to give the same put-put-put sound!:)

Funny as always Dwight :-)

Slow progress, as flying is interfering :)


Main structure done and Bonded to foam.

[ChrisPol]

Some progress over the weekend, This plane has hidden hinges for all surfaces

[Sempai-mj]

Huge rudder!

[ChrisPol]

Finally got to the turtle deck, added some pigment to the epoxy so it's easier to see,

[ChrisPol]

Sanded smooth as glass, ready to laminate

[ChrisPol]

Stab and elevator ready for cutting and sheeting, surfaces are huge

[Dwight Macdonald]

Looking good Chris! Are you using epoxy to glue the sheeting on? If so, is it thinned?:)

[ChrisPol]

Using west system 10% thinned and dyed red for visibility, then vac bagged.

I am actually impressing myself,and enjoying the build. i did a few kits in the day, but this is a builders kit, very little instruction, and quite different

[ChrisPol]

Slow progress, renovating the basement at the same time.

Tail done, will start on the canopy today.

[Dwight Macdonald]

I hope the colored epoxy will not create difficulties for covering with light colors like white.

[ChrisPol]

It should not but could add a base coat of white if needed, it only got pulled through a few seams.

Must say vacuum bagging foam core is the only way, canopy mounted and gluing.

[ChrisPol]

Canopy cut and fitted ready for gluing.

The white covers well, but the yellow seems translucent, I will pickup a roll of monokote yellow instead of ultrakote and see if that is more opaque.

[ChrisPol]

Getting there, going to do the belly in black.

Yellow monokote is much more opaque then ultrakote.

[Mezri]

Very Good job,... Thank you for sharing these photos...I enjoy evry step, waiting for the result...:)

[ChrisPol]

This is my first non arf build ever, so learning as i go

[ChrisPol]

So canopy and cowl left. Really moving along

[Dwight Macdonald]

Looking great Chris! What will you paint the fiberglass parts with?

Acrylic using hvlp & airbrush, then clear with system 3 wr-lpu topcoat

[ChrisPol]

Finally some progress one wing done. Love the size of the ailerons, there is 50 degrees of deflection.

[ChrisPol]

Well, the plane is finally ready, just need to wait for decent weather.....

[Kevin Rochon]

Wow very nice finish, did you do the graphics yourself?

[ChrisPol]

Vinyl decals were provided, paint was all done by myself

used automotive base and 2k clear coat

[ChrisPol]

If the weather holds for Thursday maiden at lunch :)

[Sempai-mj]

Long lunch time:)

[ChrisPol]

I have been able to put about 5 or 6 flights on this plane so far and it's amazing.

[Sempai-mj]

Nice color scheme:)

[Dwight Macdonald]

Great looking plane Chris! I can't wait to see it fly.

[ChrisPol]

Possibly this weekend if the weather ever gets somewhat good
