SPA 144 / SPA 144 SDI
Suter's SPA 144 is an air-cooled single-piston engine designed for small UAVs, with a compact and lightweight footprint that impacts minimally upon SWaP budget. Available in gasoline and heavy fuel variants, it is easy to integrate and features ECU-managed fuel injection and ignition with built-in altitude compensation and over-temperature protection.
The SPA 144 is ideal for mapping and surveying applications, as well as for training platforms and target drones.
