SECRET HELICOPTER
Thanks for your interest vfrpilotpb and spaced. The blades on Bug 1 were hand carved/planed using templates, the wood was spruce. when the shape was correct, i applied a layer of glass fibre and then finished of with a gel coat to put the balance and centre of mass right. The finished blades gave me no problems at all. Regarding the belts. The drive to the rear rotor worked fine, but because of the reduction required from the engine to the 90 digree g/box in order to have a decent sized pulley on the crankshaft the pulley on the gearbox needed to be about 2 feet dia. Because it hovered, i just wanted to get on with mk2. you might be interseted in the latest machine i am working on! three and a half litre v8 tandem three seats 200hp called RAPTOR regards bug
