I guess one mans trash is another mans treasure. I've flown a Model-Tech J-3 Cub I believe it was. It's not a plane many would run towards, kinna on the low quality side. It yawed like crazy on takeoff with it's short fuseladge, but once in the air, it was stable as a hummingbird and landed like a bute. I'm not a rookie by any means, but shesure was a handful on takeoff.
Glad to hear you are having fun.
