Mavic 2 Zoom ( gimbal motor over load only while flying )

[fei8820]

Recently I bought this m2p from a friend of mine ... its originally is M2P but after a small crash .. the M2P gimbal is damages ...
So I have some M2Z camera around along with board... so I install and everything works well.. until when taking off the gimbal sometimes vibrated abit.. and show gimbal motor overload.. but will not happen it on the ground.. hmmmm I wonder anything that I shall checked ?

I do all the calibrations needed... also with DJITools
everything work fine until I fly....

any reply would be highly appicated

thanks
