Steam Engines
Steam engines were just too heavy for a full-scale electric rc helicopters. Not until the internal combustion engine was invented and became available could inventors develop full-sized models.
A number of technical problems challenged the early developers of gas rc helicopterss. These included limited knowledge of the aerodynamics of vertical flight, the lack of a suitable engine, the inability to keep the weight of the structure and engine low enough, the problem of excessive vibration, the inability to deal with the torque created by the propellers, and the inability to achieve adequate stability and control.
