Low weight, a good power-to-weight ratio, and simple construction are the main features of two-stroke engines used in aviation. They are most commonly found in medium-sized drones powered by high-speed, multi-cylinder, low-displacement engines. However, this simplicity of construction comes at the cost of reduced efficiency, reliability, and even maximum power output. These disadvantages can be mitigated through the use of electronic engine control. As a result, drones could achieve higher speeds, carry heavier payloads, or the engines could be adapted for use in other experimental flying machines. For our research, we used a 1960s car engine that had been employed in various low-cost ultralight aircraft of the time, such as the Straton D7. This work describes both the modification of the engine for use in the aircraft and its subsequent adaptation for electronic control.
