Default Is it possible to do a torque-roll on a 50cc decathlon

I have seen a video of one guy doing a torque roll on a cub ( I guess it was a 1/3 scale cub with probably a 50cc gas engine)!

I would love to move into 50cc range now, but I like scale-aerobatic planes like the decathlon.

I am wondering if anyone tried to perform a torque-roll on a 50cc size decathlon!

It would be nice to combine scale aerobatics with 3d manovers that require high engine torque-to-plane weight ratio


Thanks in advance!

Depends on how much the plane weighs. You're not going to torque roll a 33% Decathlon on a 50cc engine. You should be able to do it with a smaller size, as long as it's not over about 16-18 pounds.

Will the tail surfaces be large enough to keep the plane stable and vertical? Only one way to find out.

Also you'd have to have the CG back to keep it vertical. But it would do it for sure.

That's a SPAD (Simple Plastic Airplane Design) and is made of Coroplast. He built it from scratch and modified the tail for hovering (bigger elevators and rudder). It is not built to typical cub planes, but has been modified for torquing. You would have to increase the size of your tail control surfaces big time to torque roll a Decathlon, but if you did that and add had the ponies it's very possible.

Yeah. Thats no Cub. I did see a Cub hover and KE at high alpha at Sig last year. It had a Saito 1.80 in it.

Oh no, is this the new trend? So I have to sell my Edge and Extra and get a 3D cub? Man things are changing in ways I never expected.....

If you build it yourself, you can in fact build a 1/3 scale Decathlon at 15.5 to16 lbs with a DA-50cc and it would do just about anything you want including T/Rs

Any idiot can torque an Extra or Edge.

It takes a REAL man to torque the Cub--Decathlon--Taylorcraft--Citabria etc.. and throw it into an inverted elevator right into inverted harrier with the top of the rudder dragging down the asphalt.

I have a "vintage" Midwest Citabria 80" kit for sale. NIB. Line up boys. First $2000 takes this kit home. [sm=lol.gif][sm=lol.gif][sm=lol.gif]
