I did a test run with the ZTZ99 after doing the gear boxes and idlers and all was good. Pulled out the electronics and put the bracing in. Put it all back together and went for a test before putting the top back on. Now forward and reverse are good but left and right are backwards. Then the gun started to fire all the time. Tried a few things like unplugging everything but the speakers and motors from the board and cycling the power. Any suggestions? Its all Taigen radio.
Thanks
