Using M5 gimbal and T8J Futaba controller with Canon 5D Mk3. Sometimes, on remote, the gimbal pan will slowly drift to the right. Sometimes it will not. It is steady on majestic i.e. no pan but tilts OK. If it is drifting, I switch off then switch on again. Sometimes this stops the drift, sometimes not. I have tried adjusting the trim. If it is behaving, it needs a slight trim to the left to hold it steady. If it is not behaving then adjusting the trim makes little difference. I have had the M5 since October last year with no problems till recently when this drifting started happening. Any ideas?
