WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Twin radial piston engines in wing nacelles
- Deepened pressurised fuselage on the later Marksman C
- Wing tip tanks fitted to the Marksman B and C
It is recognisable as a converted A-26 Invader with a twin-engined, mid-wing layout. The Marksman C had a deepened pressurised fuselage and wing tip tanks.
