I have been having problems with my 3 week old fc40 transmitter. Started when I was up in the mountains, I ran the naza software to calibrate my mui. I tried to calibrate the remote however it would not link thru phantom. The screws are to tight to remove to open. After a long chat with the vendor they said it was faulty and would warranty the remote. I decided to try again calibrating the compass I had 3 successful flights. I checked the motors also checked fine. The next time I powered it up it started and would not shut off with the sticks. I hooked it back to the software and changed it into course lock on s1. I went to fly today and the controller Beeb's twice then green led. The fc goes thru the starting led sequence however the motors are not starting and the bottom red and green led arnt lit any ideas?
