Markind talk to tower I had a problem with the Rotofly and they took it right back. I don't know how they will plan to help your problem, you might have to send the board back, or the whole heli. If you have not tampered with the 3 in 1 they will probley fix it for free. Heli-max is a devision of great planes. Great Planes owns Tower. Look at all the addresses, they are all in the same very general area. And when you call tower they might transfer you to great planes.
