Started as bi-plane add on for the duplo airplane of Anordvall.
Also included Mixedgears propeller, so there are 2 motor engines available for this plane.
Make this plane a 1 or 2 seater, whatever you like best.
Updated, like suggested by Ortwin:
All wings have now 2x2 studs, at both sides and at same center distance.
Updated motorB housing.
