In the old days, when a project reached this stage, you would just wrap your receiver and battery in foam and stuff them under the fuel tank. That’s what the plans show. But nowadays, with smooth-running outrunners you can dispense with the foam. And, if you have an ESC with a BEC, the battery as well.

So, I fabricated a shelf to hold the receiver. And, while I was at it, installed a switch in the recommended location.


Here's the shelf, scrap 1.0 mm ply that I salvaged from packing material years ago.


Here's the shelf fastened to the side rails with #2 hardware.



The two photos above show the Velcro installation.


Then, the shelf went back in and the antennas located inside scrap plastic tubing, both . . .


horizontally and . . .


vertically.


Next up, the receiver switch. Because this connects the ESC to the RX, it has three wires.


Here it is, installed pretty close to the recommended location.


All done.
