noob question

[RomanTheBanana]

I looked on the internet and found no info. I am searching to know wich prop is better for my .46 engine. A 12 x 6 plastic prop, or my good lookin' 11 x 10 wooden prop I just got. I read that different props are better in different categories. Alsow, what does th second digit mean? Oh yeah, its for my trainer. THX!

ok, thanks. so they are both good, I think I would go with thw wooden

10x6, 10x7, 11x6, 11x7, will work well, plastic or wood. I haven't used 11x10 but I think the pitch(10) is high for an average .46 glow engine, causing it to run slower and with more resistance than it's designed for. The motor will spin a bit faster with the smaller sizes. Purists like wood because it is stiffer but chances are you'll never notice a difference in flight. Wood is more fragile- the prop will break if it hits a blade of grass. Props in this size are not expensive and you will break them. Why not buy a few different ones and find out for yourself. If you imagine the propeller as a screw, the second number is the pitch, the distance in inches that the propeller would move forward in one revolution.

Ok, yeah, I will finally go with the 12 x 6 , and the 11 x 10 does not fit the spiner. I made the 12 x 6 run last summer and it ran fine. And yeah, I have about 5 props that I got in the kid

What is your engine .46
Is it a Os .46 Ax La. Fx ?

I used a 11 x 7 for my OS .46 Ax
Master Airscrew, it's nylon and stand some prop strikes without breaking.

My engine is a thunder tiger abc pro .46 and the prop is a tornado 12-6. You think the engine can take the prop with no problems?

11 x 7 would be the correct size for a .46

Since it's a trainer I think a 12 x 6 is a good start, gives you enough speed and good braking when coming in to land. Later on if you want more speed you can go with the 11 x 7.

11 *7 is the best
