All i need is the balls to try it

For those of a more technical nature. The small blades in the video clip were only to put a little drag on the drive system whilst testing the tail rotor. The tail drive system was run for several hours at on and a half times its normal running speed. The vee and toothed belts have given no problems to date. Belts provided a lighter method of transmitting power to the tail, negating the need for an anglebox on the boom,helping with the longtitudinal balance. As i have some 80 hp available the extra drag of the belts is not a promblem. The small fuel tank ensures only short runs are possible during testing. Each run is followed by a full inspection of all critical components.The tailboom is extendable via a carbon sleeve, this allows all belts to be tensioned at one go.
