Hey guys, after some servi reliability issues at Botfest, I've decided to upgrade to High Voltage servos for the weapon, the trouble im having is; With the HV servo connected to the NanoTwo, everything goes haywire, random movements of both servo and drive, and servo movement make the motors spin briefly...

Plug the old servo in and all works fine until it overheats and starts the twitching and convulsing again.

Have I broke something? Is the servo goosed? Or is this more likely a TX issue?

Thanks in advance for any help.
