figured I was a baffle god. After the temperatures stayed exactly the same

I had something wrong. All of a sudden, the EMS goes offline. Dynon keeps
running, but I get some big red X's across the screen where the engine disp

Each wire is solid and shows continuity all the way through. WTF! I am c
onfused at this point, and call it a day. I go out the next day, pull out t
he meter again, and by accident I touch green on one side and orange on the o
ther, continuity. I touch a motor wire, continuity. At this point I am sta
rting to see what is going on, there is a short in the line somewhere. I ha
ve wires touching in inappropriate ways. It was both a relief and rage at t
he same time, a difficult emotion to describe. For one, I was upset that so
mething so simple could cause so many problems, and the other, I knew how mu
ch of a pain in the ass this was going to be to try and figure out where the
wire was bad.

ad visible damage and exposed copper that was touching each other. It was s
o small, that if I hadn't been looking for this, I never would have even see

I'm delighted to hear that Vans is improving its composites quality. I sent my
intersection fairings back to Vans in disgust.
Warm regards

Hi team
I would like to know if the weights installed during the build on the elevators
and rudder need to be adjusted?
I ask this question on the basis of, do I go ahead and install the tip fairings
on this control surfaces using the pop rivets indicated, or do I for platenuts?
Your advice would be greatly appreciated please.
Warm regards

Interesting, Bill.
And shows we're doing it wrong, with our 100 degree-only tooling. No
wonder the nesting is never quite 100%. What practical difference does
this make? Apparently very little.
