I picked up my 2005 Ovation 2 GX in October 2024. Within a month during a flight I smelled a puff of electric smoke that dissipated and after that, my electric trim was inoperable. It was discovered that the STEC 55X board had a fried trace line on one of the boards. Got a replacement unit and that was supposed to solve the problem. Installed the new STEC 55X and with the first push of the electric trim, it fried the second board. I have a third unit that I am not installing until we figure out what is going on. My uneducated guess is the trim servo is shot but I am wondering if the trim lubrication should be checked. The manual trim works and I can move the trim full range with 2 fingers and a thumb, but it is a little tough to get through some parts of the travel. Annual was at the Mooney factory in September. I'm hoping it is limited to the servo. Any thoughts?
