Broken camera gimbal.

[ragexd1]

So a few weeks ago I was flying my drone and showing off to people that were around and I crashed it and the camera arm and yaw arm broke along with the ribbon cable.. purchased everything needed to replace and fix it myself (no warranty), got everything replaced and back together and the upon startup of the drone the gimble started acting very eractic *ill post a video later**. I’m wondering what is next if anyone else has come across this similar issue.

And as well has to replace the yaw arm motor, ribbon tore upon dissambly

Very unlucky,,does it not stop dancing or very violent movements,do you get a chance to calibrate gimble ,does it do anything or do you shut drone down because to nasty,ribbon cable in good,got a gimble light on,,did you use a dji gimble cable,some others don't seem to work well

U need to keep the same yaw arm motor casing....that was pre calibrated from factory for your specific drone....otherwise u will have problems like u do now....just google about it and do some research on it.

I fully support $gambino$ on his recommendation. I repair these cameras all the time and always swap out the old yaw motor drum when replacing a damaged motor. The other problem is, most sources of "new" yaw motors can't actually supply new motors. (DJI refuses to sell ANY camera parts to ANYBODY). Most all are used and are probably as bad as yours. The dual issue with the motors is the 2 tiny black sensors on the base of the motor. If the motor shaft flexes and the drum kisses the top of the hall sensor(s), they will no longer stabilize the gimbal. The second issue has to do with the condition of the black magnetic race inside the drum. If it is gouged and has chunks of material missing, it will alter the function of the motor and will not be stable.
DJI use to rely on the yaw arm as the sacrificial link in the gimbal on their previous models. Their yaw motors were secured to the mounting plate leaving the drum unattached, so the arm absorbed the forces of the impact. Not so on the P4's, thereby creating a whole new problem. Hey, DJI start selling NEW yaw motors so we can easily fix our cameras!

BTW, I forgot to mention, take a look at Ted Keyser"s Utube video on P4 yaw motor drum swapping. He and I have worked together on this frustrating issue.

Yup.... I mean if one was to fix it like he tried you would be extremely lucky if it worked ....he would have more of a chance if he had multiples to swap and try.....what a pain in the butt tho
