This is a picture of an original Piper PA-14 Family Cruiser. This was the first 4 seat production aircraft produced by Piper and was a direct out growth of the J-3 family of aircraft. The PA-14 is the inspiration for the Wag Aero 2+2. The difference between the two is minimal; most notable is the absence of flaps and a jack screw trim system on the 2+2. Both of these features are easily added to the 2+2 to more closely model the Family cruiser. Here is a link to a good history Piper High Wing aircraft including the PA-14. Piper High Wings
Plans, materials, and subassembly kit offerings for the 2+2 are available from Wag Aero .
