Drilled holes in the centre vertical of the rudder for the wiring to come through, to power the anti collision light. Also made a hole in the back of the fuselage, so the wiring goes all the way through the top right longeron of the fuselage.
I am hoping that I can use a vacuum cleaner to suck a string through that longeron and then pull the electric wire afterwards.
The advantage doing it this way is that the aluminium tube acts as a shield, stopping electromagnetic radiation from the wires interfering with the radio. Ah well that’s the plan anyway 🙂
