I think that plane is just too small for a 50cc gas engine. It only has 800+ square inches of wing area.

My experience with the Great Planes CAP232 with the EVO45 has been a good one. It certainly flys light on the wing. It's surprising how well it flys. I'd go with that plane. Mine weighs 13lbs 5ozs ready to fly less fuel. Performance is very good. However, for the same money and weight, I'd put a DA50 in it. I now have two DA50s and they definetely put out quite a bit more power. I'm getting over 24lbs thrust at my elevation with the DA50, and I'm only getting 20lbs with the EVO45. It flys the CAP very well and is a good fit. But it's the same price as the DA and the same weight, so I don't think I'll buy another one.

I also have a AirWild Extra 260 with the DA 50. It's a considerably bigger plane and I love the way it flys. But it costs a lot more than the CAP. If you want the least expensive "true" 50cc plane I think the Wild Hare products are the way to go.

But I wouldn't go with the plane you are looking at. Just my opinion.
