WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Thick parasol wing with a constant-chord centre section and tapered outer panels
- Pilot in an open cockpit behind the cabin at the wing trailing edge
- Almost circular tail surfaces with horn-balanced controls
A parasol-wing four-passenger monoplane with a fully enclosed 220 hp Benz Bz.IV engine, radiators on the nose and wing leading edge, and a fixed single-axle undercarriage.

History
It was designed by Walter Rethel and Keidel for the Nederlandse Automobiel en-Vliegtuig Onderneming. It made its first flight on 29 November 1920 from Maldense Heath between Cuijk and Nijmegen.
Variants
Only one example was ever built.
Where you'll see it
It flew to Soesterberg for certification but was never certified. In March 1921 NAVO removed it before its financial backer ran out of money, and it is believed to have been broken up soon after.
