Another point of indecision surrounded the wiring of the ESCs and receiver, i.e. should they live in the fuselage or the wing? Eventually I settled on mounting the receiver on the underside of the wing, and letting the ESCs dangle on the motor wires. This means that a rather substantial snake of wires has to be threaded through the fuselage as the wing is fitted, so a 1/16in balsa shelf was fitted to support them and avoid them getting tangled up with the elevator servo extension lead which runs under the shelf.
Once the wires are threaded through, the ESCs are pressed onto Velcro pads on the inside of the fuselage sides.
