Jello (or rather Jelly as it is called in the UK), might be good to eat, but it is not appreciated in
aerial video productions. The XuGong arm assembly is mounted to the frame using anti­vibration
dampers, similar to those used on the DJI ZenMuse.

To install them, first push one side of each of them into the holes in the top of the frame plate. If
they resist, a gentle rotation generally convinced them to drop into place.

Once the PCB containing the upper arm assembly is ready to mount (check and double check
that all soldering has been completed before mounting it), press it lightly against the dampers,
and one­by­one, tease the upper part of the dampers through the hole in the PCB.

A pair of tweezers, like the ones below, work a treat for teasing these in. Just close the
tweezers, sneak them around the back of the damper, and use them to poke the upper rim into
the hole.
