During the 1980s, my initial experience with helicopters involved the American Helicopters Super Mantis. It operated with a .40 class sport engine and a standard 4-channel system, with an optional gyro. This marked a pivotal era for helicopter enthusiasts where options were limited. Despite their subpar flying performance due to being early design models, I developed a fondness for this particular aircraft. Having amassed a collection of components, I believe it’s time to bring one of them back to the skies. Advances in stabilization technology nowadays allow even a brick to fly; therefore, I aim to convert one of my recent acquisitions into a smoothly flying specimen. While the original model possessed ample power with its sport .40 glow engine, I seek additional power without venturing beyond leisurely sport flying. Furthermore, I wish to forego the belt drive mechanism for the tail rotor, a known weakness of the aircraft, in favor of a direct drive system for the tail rotor/motor. However, I find myself at a loss when it comes to selecting the main rotor motor, pinion, tail rotor motor prop, suitable ESCs, and battery pack. I envision utilizing a 3D STL model to adapt the motors to the airframe, which could potentially benefit other enthusiasts interested in flying a similar model.
