At this time, I am stuck on finding a suitable gearbox for my model. Two types were used with one from a Honda motorcycle and one purchased from a local distributer. I haven't had much success in determining the "gear box drag" and it's effect on the autorotation of the blades. The blades won't spin-up in front of my floor fans when rotors are coupled to each other's gearbox. They spin-up OK when not coupled.I understand that mate, Just wondering how it all worked out?
bull shit. Tandems like to fly sideways , 200 kts been there - Fort Rucker test unit. Fritzy field - SAS not needed. only node weights.Andre;
I believe many have said that the early tandem helicopters, which were not equipped with Stability Augmentation Systems, were not the pinnacle of stability or controllability. Having read the patent, I suspect that his tandem gyrocopter will be no better and perhaps worse.

cog belts with a twist ? will workI have decided to change the gear boxes for drive belts. I am hoping to reduce the "drag" generated through gear boxes in the coupling of the rotors.
The drive belts were use on several homebuilt helicopters. The system has been proven for use on tail rotors, hopefully, it'll work on coupling rotor on my models.
