RE: Align Trex 450 Pro FBL 3gx problem
I don know if Align has fixed this issue yet or not, but some rare cases the 3GX units shorted itself out through the chrome plated case. This was due to the case was plated throughout, and the inner case surface was too close to the electronics components, it shorted and cycles power. Maybe this is your case? If so, look on YouTube. There are vids on how to fix this. Good luck.
