Looking good David. The wings are the most fun to cover. The small control surfaces are the worst. It’s going to look like an airplane soon!

A bit more progress has been made over the summer break. The temperatures have been in the mid to high 30's C where I'm building and the shed has become a regular sweat box, even with fans blasting away. But I've covered the RH wing now and the fixed horizontal stab. I agree with Josh in that the stab was by far the hardest surface to cover so far. Getting the fabric to conform around the curves takes a bit of jiggery pokery but I managed it in the end. I've also laid down the Magnetometer and pitot/static lines - but I have a question:
This has probably been discussed before but has anyone experienced EME effects from running the shielded 22 swg wires for the magnetometer close by the shielded wires from a wig/wag and landing light system ?. I'm not planning on putting any joins in any of the wires. As I'm about to fabric cover the LH wing, which is where all this stuff is, just want to make sure I'm not missing anything.
On the fuselage, I've fitted up the firewall and cowl which took way more work than I thought - I've sealed most of the joints with an exhaust system putty which hopefully will act as a seal against any CO ingress to the cockpit. At least that's the theory ....
Next up will be a temporary install of the engine to get some measurements for an Airmaster CSP prop system which I'll be installing and then onto the windshield and Turtledeck, which I plan on modifying into a two piece ala the John Evens or even the REvens mod by Ross !. It's all starting to look like something that might actually get to fly this year !!. Says he hopefully ...

Nice update Dave - I appreciate the resilience you have shown in continuing through the hot months! We hope to make another trip out your way soon so will give you a call and hope we can co-ordinate and catch up.
I think flying this year is a great target!!
cheers

Why did you run the wires on the outside of the spars and not through the spars?
You should not have any EME problems if you run full lengths of shielded cable from the cockpit to the wingtips. Out at the wingtip you will want to have the greatest distance possible between he magnetometer and other electrical stuff.
I ran my wing wiring through the rear spars without any wing root connector. If I ever need to remove a wing I will just need to disconnect the magnetometer, nav and landing lights and then I can pull the cable out of the spar.

Yep for your lights, full shielded wire and grounded at the firewall, not the tip

After I stood back and looked at the whole picture again (ie second thoughts), I think I will run the mag. wires through the rear spar. My original thought was to try and separate them as far as possible from the wig/wag/landing lights, but it sounds like it should be ok. Thanks for the input guys.

Looks great David. I enjoyed covering the wing. It's neat to see it going from being a bunch of wood and aluminum to an honest-to-god wing.
