RE: Great Planes Sukhoi SU-31
Looks to be the same construction as the Yak. Can't imagine it being any better of a flyer, and the Yak has a two piece wing, for the same price. ???????????
It is slightly smaller (4" less WS), so I guess if you have something smaller than a 50cc gasser, it would be a better choice. Curious though, that the published weight is about the same as the 4" larger Yak. I would have thought that the one piece wing would have weighed less than that.
A very good looking plane, none the less, and always nice to show up at the field with something fresh.
