Sooo I have question for anyone to answer...I got my new frame today and started to build it. As I had all elektroniks install I started with engine1 and esc, plugged it in and work as it should. Got engine 1 and 2 turning the right way..Perfect! And then when I had plugged in all 4 engine and turned it on I got the startup noise and the display lit up but then nothing! And it started to smell like varm elektroniks. The yellow component on the KK2 got very varm and now nothing works....Did my KK2 burn up for some reason or what?! It has been working perfectly until now...Anybody els who has been misfortune with this as well?
