    Actually it's not a problem, but more like an inconvenience as i can put the gimbal on free mode, then rotate copter 45 degrees so that the gimbal is straight with the copter and then put the gimbal back to follow mode.
    But i was actually wondering why the gimbal is offset 45 degrees in the first place.
    I can't seem to find out where the motor encoder is located, because to me it looks like you can not reassemble the motor incorrectly.

    the small nut that you removed or turned on the yaw axis motor has a small magnet at it's centre, this determines the neutral location for that axis, so disassemble the parts to get access to that nut and turn it the appropriate amount to correct the direction

    Thanks, gonna check the nut position later tonight. I have taken that nut off and put on countless times and i belive i can't have put it back on every time exactly the same. So i guess DJI has made something in the software that changes the position to be 45 degrees off even when the nut is only let's say 10 degrees off.

    EDIT:
    Thanks, got the yaw angle correct. It took like over 20 tries to get the nut position correct as even a very minor movement turned the yaw motor completely haywire.

    I have damaged three X5 gimbals and cameras. They went for lightweight but the ally they used is like butter. I lower the legs anytime I am under 50 feet AGL now for this reason but DJI has so many other problems with their build, it is like a prototype that nobody ever fixed, fly offs, battery discharge issues, the list is endless.

    I had my X5 replaced by DJI, then the vibration plate cracked right at the connection for the camera. I replaced the vibration plate and now 2 out of 3 times the camera is not detected during startup. Its like I almost have to squeeze the two connections together hard while turning the lock lever. I agree the X5 has its issues.

    I confirm the faultiness of that exact part in the x5 (yaw motor). Our drone came out of its pelican hard case designed for it, broken after airline must have dropped the case or something (should still be fine since it is supported with laser cut foam inside and designed to transport the drone). Once inspecting the gimbal I took it apart to find the thin metal part on the yaw motor plate cracked off. That metal is week. DJI shouldn't expect you to buy a whole new x5 gimbal because of a faulty product they manufactured and don't have replacement parts to purchase online.

    I caution those looking to get a DJI product, particularly the x5. Be aware of the flaws in the engineering of the x5 gimbal

    I saw that, but its not the yaw arm that is broke, its the motor that attaches at the top that needs replacement. The picture attached shows whats faulty. Thanks though

    Tin foil indeed..... I am now officially waiting on version 2 before I buy anything from DJI again. These Phantom 3's have been a joy.

    I wouldn't anticipate better quality components on the gimbals, design material selection errors have been prevalent since the Phantom 2 Vision series, the P3 gimbals share related issues

    and we go round the mulberry bush...

    I appreciate this is an old post, but I just wanted to post an update from my research into fixing X3 and X5 gimbals. First off, if you do attempt to take one apart to fix it, make sure you index the nut beneath the gimbal PCB, as has been noted in the past.

    A quick and easy way to do this is to get hold of a button compass and run it around the nut, whilst the gimbal is either at full clockwise or full anticlockwise rotation. I choose full anticlockwise (see this thread I contributed to on the DJI forum Manual Gimbal Adjustment (after yet another crash)). I would always check before disassembly although my experience has been that all gimbals have the same index position.

    Secondly, regarding failure of the hanger area around the yaw motor mount, it clearly is a weak point I have an X5R mount currently being duplicated in SolidWorks and will be getting a high-strength aluminium version made up as a training exercise at work. There are only a few small differences between the X5 and X5R versions, so I'll have the Solidworks file modified for the X5 once it's done. If anyone wants the file when it's finished, I can make it available.
    I would say though, that to strip the motor out of the hanger is not a job for the faint-hearted. I've done it once and have yet to put the thing back together. I'm not completely convinced I can get it back together and working once it's in the new mount. I'll post some pictures when I do it.

    Once the motor shaft was out, the motor windings prised off and the plastic insluation plate removed, I found I could gently knock the bottom bearing out of the casting fairly easily but the top one required a bearing puller to be improvised. I cobbled one together out of a long bolt, the head of which sits under the bearing. on the other end, a circular servo horn applies the pressure to the top of the casting with a couple of nuts, through which the bolt pulls itself up. Simply turning the bolt whilst holding nut steady, pulls the top bearing out like a champ.
