Finally had my class for the electrical and avionics workshop I signed up for six months ago. Great class with lots of good hands on. It was hosted by EAA Chapter 59 in McGregor, TX. They had their own large hangar with lots of space, tools, and a dedicated training room. They even have two Redbird simulators. What a facility. They are very lucky to have such a place.
First day talked about general components and wire sizing. Got to practice some crimping and then built a mock audio panel wiring harness. Plugged it in and it worked! The biggest surprise was how difficult it is to remove the outer insulation from shielded wire. They don't show that in Garmin's YouTube videos.
Second day we covered a lot on antennas which was one of the specific things I was hoping for. I got all of the information I needed. Crimped a BNC connector on a piece of coax and it is just beautiful.
We talked a little about system architecture and the the final project was to build a small panel with light controls. It doesn't look too special, but I'm proud of it.
Overall great class. Highly recommend. I feel very comfortable moving forward with my wiring, although it is going to be a lot of work.
