I have a CF gimbal guard installed on my P3A. I didn't use the zip ties it came with because it looks tacky and it fits in there relatively snug. However, I am needing to get it in there better. Has anyone out there installed theirs without using the zip ties? I was thinking about using something like hot glue to secure it in there that way I could cut it out if I needed to and you wouldn't be able to see it but wanted to see if there were any other options. Thanks.

I have actually made a support between the legs of the landing gear for my P3A. I know you are talking about a gimbal guard. Point is that I drilled  a couple small holes right at the ends of my support and then used the zip-ties to hold it to the landing gear. Seems to be working fine. No weight added, and for me it definitely stiffened up my. I think you would be fine.
