Before I contact HK, I would like to give it a try here.
I accidentally connected my 3s lipo the wrong way to my 9x, the tx has three pins and the batteryconnector has two holes, so there are two ways to connect..
Always did it right up till 30 mins ago.
I hit the on switch and poof it said with smoke..
I opened it up and saw the circuit board(the small one where the batteryconnector is) had some curled up copper linings.
Could I replace this board and where would i get it?
It is the version 1 9x, I use the Frsky module which I hope is still alive..
