Sick of trashing planes:

Hey guys. I've had three Dynam RC planes. Wrecked every single one of them. I completely trashed my T-28. I've cracked my I can fly and now it flies funny. I just broke the rudder off of my P-51. I don't know what to do. My computer (MacBook Air) doesn't support any type of flight simulator. When I fly my planes, they all have some sort of problem with them. I just flew my P-51, and as soon as it took off, the left wing would dip and fly straight into the ground. My I can fly will just hang in the air and not move forward. Also, the ailerons do not affect the plane at all. My T-28 is beyond repair. I don't know what to do, guys. I love building the planes, and they are a lot of fun when they fly, but I have pumped over $500 in this hobby with no results.
