Indoor Model airplane contest

[Rusted]

I know of a few of you that are into RC airplanes, but this is cool for anyone. The last 30 seconds he does some nose down mid air stalls, that amazing

I saw an indoor flying competion on TV once. Looks pretty cool.

 

[sandraider]

That guy can fly. :bow: :bow: :bow:

 

[Cherokeester]

Very cool, I fly the rc gliders. I wish I was that good. He must be using reversable pitch prop to do some of those stunts.

 

[I Lean]

Holy CRAAAAAP. That's the first time I've seen reverse used on a plane. Cool!

 

[crimsonride]

Definitely variable pitch prop. Those "flat out" planes are getting really popular now.

 

[I Lean]

I'd be EXTREMELY surprised if it were a variable pitch prop, that would add a lot of unnecessary weight and complexity. I'm sure he's just reversing the electric motor.

 

[Jay5.9L]

not my thing but that guy got skills

 

[JoeT]

:bow:

 

[MRJ]

Holy CRAAAAAP. That's the first time I've seen reverse used on a plane. Cool!

Yeah, what he said.

Pretty cool

 

[Brett]

wow

 

[RockMonkey]

Yeah, it wouldn't be very efficient rotating backwards, but just reversing the motor would produce that result. Now if it were a glow motor it would be real impressive. He is an excellent pilot. Some of the less impressive maneuvers he did are extremely difficult!

Hey, i know my stuff.

Told you I'd be extremely surprised. I was right, I'm surprised!

You cant just run a prop in reverse and reverse the thrust (although you may get some). They are actually airfoils that create lift not just a flat blade moving air.

What he said!^^

Why it said it wouldn't be efficient. It would work, just not very well.

 

[crimsonride]

Yeah, it's not as efficient but that doesn't matter. You're forgetting that even with a variable pitch prop you're still using the back side of the blade to push air.

 

[I Lean]

That variable pitch prop you posted has a symmetrical airfoil, so it's equally inefficient either direction.
