Hi all new to this forum ' and gimbals ' anyhow I have an odd problem' I have fitted the walkera G-2d gimbal plus the FC40 camera'... it balances no problem in both tilt and roll' when not powered up... have fitted a pitch tilt knob to Tx and done a cal... plus set limits' no problems'... I used one signal wire from naza F2 signal pin to walkera pitch tilt signal pin... plus spare power wire grey/ red from phantom for power'... once switched on the camera looks ahead or down and anywhere in between depending on the position of the tilt knob'... BUT its only OK on the work bench... if I lift it and tilt the model the camera rolls to the looking down position ???.... the funny thing is if I disconnect the pitch tilt plug from the gimbal control box it works fine'... If I trim the camera angle using the V2 trim pot... However much I move the model around it holds that angle!!... It's as if the tilt motor does not have the power to hold the weight at an angle of say 30/ 45 degs or so when it's connected to the naza m.. any ideas regards glo.
