The propulsion hub covers the components that turn an airframe into an aircraft: gasoline engines, jet turbines, electronic speed controllers and flight controllers. FlySpark stocks DLE gasoline engines from 20 cc to 222 cc, Swiwin jet turbines from 22 kg to 60 kg thrust, the BLS 60 A 4-in-1 ESC and the F4 V1 flight controller for FPV builds, plus paramotor engines and generators.
DLE twin and four-cylinder engines (DLE 30, 60, 120, 130, 170, 222) are the standard choice for fixed-wing and VTOL UAVs in the 10–60 kg class: proven reliability, electronic ignition, muffler kits and starter-generator options for hybrid power. Swiwin SW220B and SW600PRO turbines serve jet-powered targets and high-speed platforms where thrust-to-weight is critical.
For multirotors, the BLS 60 A 4-in-1 ESC (BLHeli_S) and F4 V1 flight controller stack give a compact, field-serviceable core for 5–10-inch FPV drones. Match ESC current to motor peak draw with 20–30% margin, and choose engine displacement by aircraft weight and required climb rate rather than by cruise power alone.
