RE: how tough are receivers?
As I said earlier, you can move them with no problems. While you are doing a 2.4 Ghz radio and this doesn't apply as much because you don't have the long antenna wire, Minnflyer and I regularly move radios in this very manner. Since we do reviews there are times that we will put the radio in a plane JUST for the review. As most times we know that we're not going to keep the planes after the review so it's a waste of time to permanently install the antenna wire. So what we do is run the wire for the antenna (72 mhz radio) down through a plastic tube. We then install the receiver and stick that tube down through the fuselage. This works perfectly and makes it easy for us to remove the radio and move it to another plane.
With 2.4 radios this is even easier because you don't have the long 3' of antenna wire. An easy remedy for doing this with a 2.4 radio is to put a bit of velcro on the outside of your padding for the receiver and it's remote, and the mating part of velcro in the fuselage where you want it to mount. Then you can simply "stick" the receiver and remote in place when you move it from plane to plane.
Hope this helps
