I'd suggest that you answer your own question with your own gear. Make up a small board with the Rx, pack and a servo on board. make it so that the installation can be capped off with a couple of aluminium pop cans to totally enclose the gear other than for the small holes for the antenna and the pushrod that exit the equipment area. Set up the servo so it waves a flag at you so you can see that the signal is still being received and you have control. Then with the setup sitting up on a 6 to 8 foot pole off the ground get a handle on the range. Then put the cans on and try again. Have an assistant rotate the setup so you can see if at some point the metal of the cans shields the signal from reaching the Rx.

Carbon fiber fuselages are bad enough. But now you're upping the anty with an all aluminium setup. You're basically creating a shielded box which will most certainly make getting any sort of radio signal into the box a problem. And even with the stub wires sticking out the effects of the metal so close to the wires might just affect the range. So testing to find out is pretty much all you can do.

If your Tx has a ground check setting be sure to use that so the power output is reduced and you don't need to walk as far.
