Hi synte. I have a new belt CP on its way to me now. I have been reading up on it every where I can. I have come across others that have had the same issue. There is a plastic covering over the heat sink on the ESC. Remove it. This has solved the problem for some. For those that this didnt work, they replaced the ESC and solved the problem. Go to a 35AMP unit with a 3AMP BEC. Its only a couple of bucks more than a 30AMP. It will allow you to upgade the motor and servos later. The other issues that seems to crop up with this bird are a glitchy Tx/Rx system and a cheap gyro. Alot of people that upgraded to the $30 Esky Heading Hold gyro were not happy. Others upgraded to the $55 Telebee or better with excellent results.
