Getting close to finishing now so some small outstanding jobs to do including wiring starter solenoid protection, a stuck starter indicator connection and external level button on each stick top hat. I also trial fitted the registration and polished the fuselage ready to apply it.

I received the registration vinyls on Friday so today I need to ready the fuselage for them to be applied. Just a case to working out the best placing for them. Along the line of paintwork line or along the rivet line? that’s the question!
I’ve bought a polishing machine to make the job easier with some G6 cutting liquid cutting compound. It takes a bit of getting used to using it but it makes a good job it. The paintwork needs to be de-greased before I can apply the registration letters.
When I sent the aircraft for spraying they noticed that one rivet hadn’t been squeezed on the trailing edge of the wing. So Ian brought his rivet squeezers in with a special head for this type of rivet.
A little more wiring to do. A diode is placed from the starter solenoid to earth to kill any spikes caused from the contacts releasing when starting the engine. Also I’ve wired up a contact on the Dynon screens to that will show a ‘stuck starter’ situation. I was a little worried that a higher voltage may find it’s way back to the EFIS so I’ve protected the connection with a diode to prevent spikes and a 1 amp fuse.
