Separate 1000mah powering 2 axis gimbal working well but I'm unclear where to connect the ground wire for the control board for gimbal pitch control. first I made the mistake and used signal and ground wire to A10 or 11 of apm and caused a brownout. Luckily hex took off but landed quickly and safely without damage. Can I just use a single ground wire to an open ground pin off output servo rail of APM? Or could I use an open ground pin off RX?
Thank you for the help. Jay.
