If you have the 5v/3a version you are PROBABLY good. Make very sure all the servos linkages, can rotate freely into all the stops in the servo. If they can not and you do a long stick command at the end of travel, it will overload the switching BEC and shut down till it cools off enough. I noticed where they stated the throttle trim was available. Send them a E-Mail about yours not holding your adjustment after programming it with a PG card.
