|---|---|
| E — Engines | 2 × piston, fuselage-mounted |
| F — Fuselage | Engines in nacelles at the fuselage sides driving the rotors by long shafts |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Twin intermeshing rotors
- Engines in nacelles at the fuselage sides driving the rotors by long shafts
- All-metal enclosed fuselage
