Had a couple of 40 size GP Cap's myself. They were dubbed "snapping caps" for a reason. If you loose an engine forget about streching the glide. When doing spins, stop very early and get plenty of speed before pulling out try to soon and it will just spin tighter. As far as low speed handeling it really fools you. It comes in looking rock stable....slow it down a bit more .............pull the nose up for a flare.....and........BAM!!! it stalls with a vicious snap and gives zero warning before it goes. They are a challenge to fly. I sometimes miss them. Be carefull and enjoy
