I had a bunch of family drama that set me back years, but I'm back working on it. Right now I'm working through the trim system and finishing my skylight.
For the trim system I'm going to mount a ray allen servo in each elevator and have them directly drive the servo tabs. The reason is because I don't like the servo action on the trim. I know some people say that they like it, but everybody that flys the airplane heavy and with aft CG is united in saying that it's more of a handful than it should be.
By using a second ray allen servo I get some redundancy, electric trim, and it's just simpler and lighter weight. I have a servo controller board I'm working on that will sync the two, only allow one to be 20% out of alignment with the other in case one fails, has a return to neutral button, and a rotary encoder to allow the overhead trim wheel to still work.
This bit of engineering is certainly taking longer than I hoped, but I'll have an awesome trim system, and I'm nearly done.
As for skylight, things are cut and fitted, I just need to tack everything in place then finish weld.
I also have the boot cowl and panel sorted out.
So next will be running wires for ELT, antenna mount, and some tabs for various things. After that fuel lines.
So I'm not all that far, but farther than last year.
