I
I have sold to VP-1

The plane was built from Evan Aircraft plans
Basic as it gets ..Rag Wing, tail dragger , open cockpit, 22' W/S
The best design feature was it had a Full Flying Tail, no elevator/rudder.
This was originally a homebuilt in Popular Mechanics, way before Kits became coool..

The Rotax you mention are used a lot , but originally , guys stole them from Snow-Mobiles.
The engine for the VP actually came out of a 1966 VW Flower/Peace Sign BUS...
Had a Hegy wood prop... 56/45.

Do you do Sun and Fun or Oshkosh ??
