Hi, Is there anywhere I can find a larger "keyed" aluminum tube that will fit my current Movi M5 (MR version)? The one that came with the Movi M5 is to short for fitting the leg of the MR kit. I want to be sure that the Movi stays put when I'm flying with a little heavier loads. I haven't been able to tighten the screws enough for it to not move slightly in more aggressive moves. It is critical to have the balance stay in mid air, if the load comes unbalanced we could have the risk of the whole copter ending up in the famous "wobble of death" not being able to compensate the shifting in the center of gravity. Thanks.
