She leaped off the ground so fast, it was as if she was waiting for this day as much a s me. I left DFW Class B as quickly as possible and scooted south, climbing to around 6,000. Of course breaking in the engine, I was full open. The w hole time during the climb, I was watching EGT and CHT like a hawk. Every E GT report 325, every CHT reported 450, Oil Temp about 180. At this point, I figured I was a baffle god. After the temperatures stayed exactly the same once I hit cruise, my baffle achievement theory started to fade. I figured 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 lay is.

I start running through everything I have direct contr ol over that is feeding the EMS. Volts, Flaps, Rudder Trim, Aileron Trim, E levator Trim....

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. > > I decided to just replace the whole wire, and not try to chase down where t he actual short was. > > I got the wire out, and there was no visible damage anywhere.

Doing this until I got to about a foot of bad wi re left. Then proceeded to strip that bad foot of wire. I must have pinche d this section of wire at some point, because the internal individual wires h 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 n it as a problem. > > I got the new EMS in, check the sensors, everything looks good, and decide to go for a flight this weekend.

The canopy, compared to the one I received years ago is much improved quality wise. Does that mean that all the VAN's f/g quality has improved. I was so disappointed with my gear leg intersection fairings that I got a set from RVBits.

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.

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?
