Since the left fuel tank has been deemed leak free, I re-attached it to the wing today. The Z brackets don’t line up exactly, but a small dowel and a little prying and it all bolted together ok.
All the wiring and other parts came in, so everything is now in the left wing and its basically ready to have the lower skin installed and be marked as done. There’s no rush to close this out, so I’ll get to it eventually when I run out of other things to do.
I pulled the right wing tank off and completed the pressure check. We saw some concerning bubbles at first, but couldn’t be sure if they were from the soap bubbles collecting together as the water ran down the tank or if it really as air escaping the tank. The longer we looked at it the more convinced we became that it was the former and that the right tank is also leak free.

While the tank was off I deburred the right wing main spar before reinstalling the tank. I also final installed the right wing wire conduit and hooked up the auto-pilot servo connector and safety wired it on. The bolts I bought for the conduit mount were regular steel because they didn’t have M3 machine screws in stainless steel at the local ACE hardware. The end conduit mount on the right wing though will have to be replaced with a SS bolt though so it doesn’t interfere with the magnetometer that’s going in the right wingtip. I’ve seen people forget to make that swap in the past and spend ages trying to de-bug why their magnetometer doesn’t give sensical readings.

Some steel 3/32 pop rivets I ordered a while ago arrived today. Since the QB tailwheel mount goes in a little differently than the standard build, it’s impossible to reach the lowest 8 rivets on the forward side of the 712 bulkhead. The tech advisor told me to put any rivets in there I wanted, so I ordered some Cherry max CCR-264SS-3-2. They’re steel 3/32″ flush head rivets and should be better than anything else I can put in there and they look pretty good too, for pop-rivets. I also installed the 2 “keeper rivets” in the tail wheel mount, and installed the longer AN4-10A bolts. These were needed since I installed 0.100” spaces on the forward side of the mount to make the faces flush.
