Yep...more Trim Wiring
Today I continued working on the trim system. I had previously decided to use the ray allen LED trim indicators that come with the kit. This is because the Dynon did not support trim indicators at the time I cut the panel. If I had it to do TODAY, I would use the Dynon to display trim. You can see how the traim is displayed on the EMS screen in the lower right.
Oh yeah...one of the neat things about using a two-screen setup is you can display the engine monitor screen on the EFIS and then as you adjust the settings on the engine monitor you see the engine monitor page change in real time.

Here are the trim indicators. I wired the aileron indicator to the servo. You can see that in the middle position it illuminates the two middle lights. Interesting. You may remember way back when that I complained about the indicator having an odd number of LED's. Well, they light the two middle as an indication that you're centered. Pretty cool.
Next I worked on the passenger stick wiring a bit. First I had to fix a problem with the wiring for that stick. When I soldered the leads on to the terminals a while back I blindly followed the instructions for the PTT button. They have you solder one terminal of the PTT button to ground, but my intercom basically has you do it a little differently where you're closing a separate circuit and that does the trick. Sending the PTT to ground would theoretically work with my intercom but I think it would be it more susceptible to noise.
Here you can see that the connectors fits perfectly into the stick 'socket'. It's an .062 9-pin Molex, in case you're wondering.
