Ihave a bent gimbal arm.  This is not a camera off horizontal axis. This is an actual bent arm, from what I can tell.  Never lend yourUAS to anyone! See pics.

1- Are just the arms availablefor purchase?

2- If they are not availablefor purchase, has anyone ever straighten one out?  If so, do you have a video or instructions?

Some users have reported that they have had success by removing the arm and very gently bending it back. Some have made wood jigs to use to straighten others have used small channel lock pliers to bend it back.  I have seen the ares on eBay for around $100. There are videos on you tube  under" Phantom 2 vision plus gimbel" that show how to disassemble and may have one or two on straightening the gimbel.  Either way you have to be gentle with the ribbon cable. It tears easy.

To whom may be able to help,
My drone recently crashed on grass and I am not sure if the gimbel is suppose to look like this. Also, while the drone is on the ground not moving, the camera can be seen moving to the right very slowly on the remote screen. Please help!
