Suter's TOA 330 is a twin opposed-piston air-cooled engine designed for mid-sized UAV platforms. With low vibration and smooth operation, it offers excellent endurance and payload performance, and is available in gasoline and heavy fuel variants.
The TOA 330 family is easy to integrate and features ECU-managed fuel injection and ignition with built-in altitude compensation, cold start support and over-temperature protection. It is ideal for civilian fixed-wing mapping and surveying UAVs, as well as for long-endurance tactical and security platforms.
