Actually, I think that the Wayfarer in 2/72 and the Acrostar in 4/73 are much more closely related (Dewey on the design of both). Both are about the same size and appearance. I had a Acrostar for close to 500 flights. I powered it first with an OS FSR61, then up engined it to a ST .75 swinging a 13-5 at 12,000. Pretty much unlimited vertical at 7 1/2 lbs dry.

The Acrostar is incredibly strong, with front and rear spruce spars in a "D" tube wing, and solid lite ply fuselage sides. I flew mine through another airplane, with very slight damage to the stab at the top of a 400 foot climb. The other plane was totaled coming down in little pieces.

When set up slightly tail heavy, it can tumble end over end across the sky and do some of the best sport flying you can imagine, yet is so easy to take-off and land.

I liked mine so much, that I bought 4 more kits (Airtronics) on auction the last couple of years.
