Blade, re the pirouette. If the direction of the pirouette is anti clockwise the heli will decelerate - if the pirouette is clockwise the heli will accelerate. That's the theory anyway - works that way on a real Huey UH-1, I haven't progressed that far on the Honey Bee yet! The spare parts have arrived so I'll go & fix the darned thing. Good luck with the manoeuvres!
