Absolute fantastic clip Adrian!

I definitly agree that an expansion muffler would be preferred rather than the tuned pipe in heli aplications. You get a feeling of not being in full control of the chopper using a too hot pipe. Perhaps there were more problems than the engine in my case [&:]. My skills stretched to rolls and loopings. I could throw in a 540 too. A bit left to the skills of the guy on the video!

Actually I think the Kyosho VR 46's problem was too small rotor blades, rather than lack of horse power. It can not capitalise on the higher torque of the OS 46 FX compared to the OS32.

Cheers!
