Just made a modification to the canopy so that it fits snug rather than tight. I deepened/lengthened the notchs on the bottom of the canopy where it contacts the skid leg a 1/2". Now it fits snug without forcing and takes most of the strain off of the grommets. Looking at other 2200, 3S batteries I noted that the ones I have are on the lower end of the length range, 106mm.
