sorry if I was a little vague before. you have 4 rotors, 1 in front, 1 in back and 1 on each side. The front and rear rotors are positioned so the blades rotate on a horizontal plane (give lift). The side rotors (angled) also provide lift, but being rotated 45 degrees forward, also provide some propulsion forward and the ability to rotate around a vertical axis. Then, all 4 rotors are connected to 1 engine. engine speed increases, the heli goes up. 1 servo connected to the collective on each of the front and rear rotors. collective up on the rear and down on the front will lift the rear and provide forward motion. The same for turning, 1 servo connected to the collective of the side rotors. I want to use tail rotors, because they only have a collective, no cyclic, so less weight. And a belt driven system would be a lot easier to make. I can machine the gearboxes required for shaft drive rotors if I have to, but it's a lot of extra work. So again, back to my question, where can I get complete tail rotor assemblies?? I can find individual parts, but that will get expensive real quick.

Thanks
