I’ve enjoyed my Crusader GT2 for over a year and it’s been a tank till it was involved on a moderate crash last weekend. Issue is that it wont arm (on a switch) since and flashes “LOW VOLTAGE” reading 0 volts on the OSD with a fresh battery. Running Bata flight, Teranas 9x w/Frsky control, 4s bats. The receive light turns green when firing up the Tx indicating healthy up-link. I’m somewhat experienced but this one is beating me so far. One thing I did notice was that 2 of the plastic screws that hold the board stack in place had sheered off so I’m guessing that saw some impact G’s.
Any help is much appreciated
