HEQ gport gimbal twitch when using sbus

Gimbal often twitches at all pitch angles but is much worse at about 45deg down. It does not do this twitch when using PWM. It also has quite a bit of roll drift. (Horizon not level).

Mine does the same... did you find any solution?, i also try by pwm and its the same

Didnt have time to work on it for a while. Someone said the 'new' firmware is better. Im not sure which one he meant. The only new one I see (from yesterday) is for mavlink. I would like to use that but there is no information how to set it up. ie which gimbal to select in Mission Planner etc.

@@vincehogg8935 that firmware that includes mavlink may work better but I can see that for using with ardupilot you need to compile it, since the include the source code for driving the the gimbal by mavlink commands

Tested today with the FPV firmware. Very bad gimbal jumping. See my vid loaded today. Im wondering if I have a faulty gimbal. I tried pulling off my sbus wire and the gimbal just stays at its last setting. It dosent jump around.

All my tests have been in angle mode. I tried speed mode on sbus and it behaves like the 'home' is randomly applied. I then tried speed mode with PWM connections and it seems fine (with FPV firmware 000019). So only one way working. PWM speed mode.
