Keep it and fly the CR^$ out of it. My first trainer after I learned and soloed I removed the tricycle gear and made it a taildragger. Then I flew it some more. I got to a point that I had to bolt the wings down or pile on 20 rubber bands to keep the wing on. Increasing the control throws, and advanced aerobatics can be had as well, slo flight, flying backwards in wind, short field takeoffs and landings, stalls ect are all very fun with a trainer. Flying upside down is a challange with the dihedral in the wing being negative when upside down.

I was finally done with my poor old trainer when a teen I was teaching had the heart for RC flying but not the $$$ to get in. I gave him the plane, complete and handed him the receiver when he soloed, his face looked like this---------------->
