R/C Airplanes

[riteflyt]

well the last thread I posted these in rubbed the original poster wrong so I will put them here.














these were shot at greater southwest areo modelers club located at 820 and Randal Mill
Again let me know what you think

Pretty amazing vertical flying shots, Norm. That plane looks much bigger than many I've seen.

awsome shots I love #5 the best

Thanks Bruce, its called 3-D Aerobatics. Basically the wing is not creating the lift its all done with the power of the engine.

This particular plane is 41% of full scale, with a 150cc twin, two stroke gasoline engine making about 16-18 HP. the plane weighs 40lbs has a 134 inch wing span and swings a 32x10 inch carbon fiber prop.

Its a very impressive thing to watch.

I like the exhaust in the second one and the hovering in the last. It's been a while since I've been out to that field, do they fly every weekend?

Well last weekend was my first time out there, I did join so I will be back out there next sat morning.

I didn't think that plane was as big as it was until the guy walks up to it towards the end to provide scale....

Thanks Jim, that is about a 30 inch wing span foamy, weight is probably about 16-18 ounces.

Here is an idea of the size of the plane that he is flying in my pics

cool plane and pics. looks like fun. is it a model of an extra 300? is the reason the model is vertical in all the shots because the wings provide no lift (judging by the cross section in the last shot, it's not shaped correctly, i guess?)?

sorry for all the questions norm...you know i love anything aerospace....

Yes you are correct it is an Extra 330S, I don't understand you last question, but the plane is hanging in the air on prop thrust, the wings do nothing except the ailerons will counteract the torque of the motor.

I hope that answers your question

[chempilot]

thanks norm, you answered it. did you ever finish your airwolf model?

[riteflyt]

that was not mine, I was helping him build it for a magazine article. My heli is a TRex 450 SE, it is a medium electric heli.

Cool. So how can you glide or flare with no lift from the wings? What do you do in the event of engine failure?

If the engine fails you crash! and take a trash bag with you to put the pieces in... JK at souch a slow speed and low to the ground its not usually that bad.
