Dual flight control build

I got the roll damper installed today, hopefully I will have time to do the pitch tomorrow.

Managed to get a bunch of fiddle bits finished today and cut the plate I'll use for the rear support. Quality control is taking a hard look at things in this photo, I'll be sure to have issues I need to fix...

So last night I noticed that during rapid roll movements the spherical rod end were moving on the bolt I used to hold them. There was .050 difference in the bolt diameter and the hole in the rod end. Tightening them helped a bit but wasn't the solution. I went to town to look for some cheap ball joints with a stud but all the cheap ones had the same runout. So I decided to give something a try and it worked like a charm. I turned down a steel rod to .080 oversized and pressed it into the hole of the rod end. The force of the pin expanded the steel ball insert to a snug fit with the brass sleeve, no measurable slack. Only took me three tries :D .010 oversized bent the pin before I could force it in and .050 was a nice fit but didn't effect the total runout. Saved me a few buck and was a good exercise in turning to a precise diameter.

Love the counter-balance idea! When I saw it, a little light bulb when on over my head and I said, "Ah ha!" I happen to have an old el-cheapo telescope that I bought at a yard sale years ago which has a similar, if somewhat less refined, counter balance!

Thanx!

My pleasure Fighterfan, not sure where I first saw the idea but like you it made a light go on. :D

Started work on the panels for my generic simpit.

This was something I saw (probably on this site?) and kept in the back of my mind for later. It's a fake fuse panel that will give me access to a few key strokes I normally use in the cockpit but aren't exactly aircraft related. The fuse holders are modified to fit a small push button switch.

That's clever. :) g.

Thanks Geneb, not my idea but I do thank whomever had the idea and posted it previous to me. ;)

I did do a bit more work on the controls today, the main axle will be connected to this linear slide via springs, the slide will be attached to a linear actuator giving me a basic electric trim. Once again not my idea but I liked it when I saw something similar on a dual yoke setup.
