How to Choose in This Family
- Power class. The line steps 8.68 → 13.97 → 21.6 → 31.5 → 37 kW; pick the smallest unit that covers cruise plus climb margin — excess kilograms cost endurance twice.
- Integrated electricity. Airframes that need 28 V onboard power take the XW630F starter-generator or 4TK66FD coaxial generator instead of bolt-on alternators.
- Stroke and fuel logistics. Two-stroke members run 92–95 RON with mix oil; the four-stroke XW996F trades weight for plain-gasoline simplicity.
Where this model sits: XW996F is —.
