OK, I've got my first profile, a Katana V2 46, under the wing hatches are these big cavities. HOW in the world do ya mount the electronics so they don't go crashing thru the sheeting on the first bump, and HOW am I supposed to have the flexibility to adjust the cg b4 permanently mounting them?[sm=bananahead.gif] I thinking about some kinda rail/tray thing. I thought this was an ARF?
