The one time I powered up my
MA2 without removing the gimbal cover was enough to convince me to find a way to prevent its recurrence. The solution I came up with isn't particularly elegant, but it seems to work, for me at least.
I attached a generic wrist strap/lanyard to the hole in the rear tab of the gimbal cover:
Note that there are no metal components on the strap to scratch the
MA2.
A close-up of the strap's attachment point:
And how the strap exits the quad with the gimbal cover in place:
The strap is looped over the extended rear arm before the gimbal cover is snapped into place:
The key here is that the strap is short enough that, in order to remove it from the extended arm in preparation for a flight, the gimbal cover
has to come off. A longer strap would allow you to unloop it from the rear arm without removing the gimbal cover, but that would defeat the whole purpose of this exercise.
The rear arm can be folded normally with the strap over it, and doesn't take up any additional storage space. No need to drill anything, use hot glue or mess around with tape.
However, if you're in the habit of powering up your
MA2 with the arms folded, then this method won't guarantee that you'll be reminded to remove the gimbal cover.
