Thanks!; that is what it looked like "reverse-engineering" it. Does the control arm then "float" up if the strut is compressed?

Yes.

You'll have to try different springs until you get the desired tension.

I started building the tail wheel assembly this weekend. I purchased 3/16 brass rod for the yoke, 1/4 in. brass rod for the strut and 9/32 brass tube for the bearing shaft. The spring is from Ace Hardware and will compress enough to absorb a significant landing (hope to never test it though).

Fortunately, I was able to get some help from our A&P mechanic and drilled a #11 hole in the 1/4 in. brass for the yoke. The yoke was formed around a piece of steel round they had sitting around.

After forming the yoke, It was inserted in the strut and then soldered in place. The assembly is very strong at this time and should have no issues. I will solder the spring retainers (washers) on this week and trim the strut and yoke arms.

Our mechanic also ordered a piece of 7/8 in. aluminum round to make the RDS couplers. He has a machinist who can turn them in no time.

I think he should send it to me, for approval.

LOL! I will certainly do that Tom! I soldered the washers on the assembly to retain the spring today. Just a note, don't use the brass strut to hold the washer to the bearing tube; use a wood dowel!

I will work some more tonight on the empennage (had to say it since it was beat into me during flight training) and build the support for the rudder servo. I picked up some 1" brass strips to secure the servos. Should have the RDS couplers turned this week and the remainder of the balsa to work on the fuse.

Blame the Wright Brothers, if they hadn't been so secretive and so aggressive in patent enforcement to the point of trying to stop anyone else from build aircraft in the USA the French would not have taken the lead in aircraft development and named everything. We're just lucky Congress stepped in when they did and forced them to sell the patents to the government.

I'm finally back; I have been all over the Midwest on business lately and could get back to my build room. I have completed the jigs and will post them shortly. Stick balsa and bass have arrived so I will try to get fuse inner frame together this weekend.

RDS should be done soon also so I can start working on completing rudder assembly.

That's funny!!! Unfortunately my biz can be sporadic with little warning as to when and where I need to go someone. Lately, I've had some place to go everyday so I'm ready for a break.

I just got "volunteered" for a training seminar to show how quads or "drones" as everyone else calls them can be used so I guess that is going to take a little of my time as well.

Here are some upside down images of my magnetic jig fixtures. I've tried to rotate them but the coding in the forum is not accepting the changes I made.

Jeff,

If you have to build on the ceiling, you need a bigger shop!
