So they have found a solution.,,have the customer to do something they don't like. Too bad, it's the way it is. How many businesses stay in business by making the customer feel bad? I never talk to my clients this way.
The shell has two points of fixation next to the motor mounts. Those are the ones that are breaking. When they do, it allows translation of the shell and furthers the crack. The next point of fixation between the arm is half way down. It is a #8 torx screw, but it doesn't have a machine thread. More like a standard wood screw. What there needs to be is one more fixation point on the arm. Making two. The two fixation points by the motor need to be thicker where they curve into the shell. Externally, that's the area showing fracture.
For now. Loosen the two screws in the recessed holes. Not the 4 motor screws. Re torque them but don't get aggressive. They have blue Loctite on them, so they should stay put.
Next, tighten the screw in the middle of the arm. How tight? Torque the end of the arm to see if there is movement in a rotational way. If you get the middle screw right, the rotational torque on the arm should decrease if not stop and make it rigid. This will help translation of the shell pieces and hopefully prevent the two fixation points near the motor from fracturing. I noticed I had a lot of play from the factory between the shells and along with improper application of the screws near the motor or poor design, they cracked. I would tune each arm by tightening the middle screw in the arm until there's no rotational torque on the arm. Rotational torque means shell translation, which means movement at the two standoffs by the motor. Which means fracture. They could solve this by making one more fixation point in the arm or having a notch where the two pieces come together where they can't translate. People putting zip ties next to their motors get this.
If you already have cracks, you will have to fix it yourself by gluing the standoffs internally or sending it in. Or using a new shell......oh wait, we are not smart enough to do that on the phantom 3.
