you might check your engine /wing incidence. being a mid wing airplane, the edges like to fly at 0-0. as was said, the pulling to the canopy is normal on downlines. you didn't mention what it did going straight up, and that's where a lot of people start playing with incidence. you should be able to transition from horizontal to vertical flight without elevator corrections. it's probably worth mentioning that one of the locals buried a 39% 540T when he tried to apply pattern know how and changed the wing incidence. the first time he tried to land it, it wouldn't settle, and it stopped flying about 10' in the air. no more edge.
