Status: offline 		Hi,

I have a new and unflown TWM 1/3 Clipped Wing Cub, I also have an OS GT55 hanging around.

Do you think the OS will fly the plane, and have reserve for decent aerobatics? I dont need it to hover, I have a 100cc python and C-ARF's for that.

I just think putting all that power in a J3 is crazy.

Thanks,

C.

Status: offline 		I agree a 100 cc is not needed for a 1/3 scale Cub... I have an AXI 5360 on 10 cells in my 1/3 scale L-4 and it flies very light...

Status: offline 		My WM J3 1/3 scale CUB has a G62 for power.
I think that is a nice power combo.
Use it for hauling cameras for air to air filming and as a Glider Tow plane.
Could it use more power, depends on who you ask, I like it.

Your 55 should do just fine.

I would say half to three quarters power would be scale CUB flight.

Status: offline 		I have seen 33% Cubs fly with both Quadra 35s and OS 3.00 Twin four strokes. They both flew great, and not over powered. It was a scale flight. It actually had to roll for takeoff and dive for loops. An OS 55 would be grreat.

Status: offline 		should be perfect.......no need for 100cc at all unless you just happen to have an unused one laying around.

Status: offline 		Bunch of guys at my field fly them with Da50's, G23, G38, G45, G62's.

They will pretty much fly on any decently sized motor. Granted the smaller engined plans are sllllooooowwwww. And light
