RE: 2.4 GHz reciever placement
You should have no problems placing the Rx anywhere inside the fuse. There is no need to have the antennas poke through the covering. I fly JR/Spektrum, but I follow many of the threads dealing with all radio systems and I have not seen any indication that Airtronics 2.4 Rx's need to be placed in some special way with the antenna through the side. If you had a carbon fiber fuse than you might need to take special measures.
