I am having similar problems. My a-10 took flight (brushless) but the canopy fell off during some inverted flight then I lost control 5 min into the flight (don't know if a motor failed or it was a transmitter problem) and it came down like a rock. I had another problem with a brand new F-16 esc catching fire before I ever flew it. I have had radio silence from Nitro Planes, no new esc. I guess we get what we pay for. Go to a local hobby shop where you can actually talk to a person and get some support. No matter how much cheaper these planes are, if you have to replace them weekly the savings quickly go away.
