Have a Trex 450 and it was flying fine. I went to put it in a airwolf fusealage and all the sudden when I plug the battery in everything works except it won't spool up. All the servos move but no power to motor. Also I put a new align ESC and it won't work either. The first ESC that came with it that I thought was bad quit making the sounds you hear when you plug it in. The new one I just put in doesn't make any sounds either. They both should make startup sounds. What else could it be? The new ESC I thought would do it.
