FAQ
Do the engines support heavy fuel (JP-8)?
The current family runs gasoline (93/95 RON); heavy-fuel variants are on the engineering roadmap — ask for the roadmap in your RFQ.
What makes EFI worth it on a UAV?
Automatic mixture compensation across altitude/temperature, easier cold starts and lower fuel burn versus carbureted equivalents (manufacturer specification ≤450.1 g/kW·h for XW630F).
Can the engine power avionics directly?
Yes — XW630F integrates a starter-generator delivering 28 V DC up to 2.8 kW with a 100 A rectifier (manufacturer specification).
Is installation documentation available?
Yes — mounting interface (170×135 mm, 4×φ8 bosses), weight distribution and cooling guidance ship with the integration package.
