    Found a few pics in the build cd showing the aileron end with tube, the wing tip with tube, inboard wing with tube, and one of the composite hinges out of wing, and the hole where it goes into the aileron.

    Short moment shouldn’t be an issue. As long as the servo has leverage to move the aileron, then the slave rod should effectively translate this movement to the other aileron. Look how short the moment is on the full scale. Photo is from a Pitts Model 12, but very similar to the S1.

    My biggest concern is the arms and slave rods being capable of handling the load. In my test yesterday the 1/8" 5 ply plywood was actually twisting. I am looking at using .080 bi directional carbon fiber laminate for the arms and carbon tube with a rod in the middle. I do believe it will be strong enough but you never know until it's done.

    The Proxxon chop saw showed up today, woo hoo! This is one sweet little piece of equipment, it sliced through a 1" square poplar and 1" pine dowel like it was nothing. I can't wait to see how the fine tooth blade slices through balsa but I am sure it will be with ease. Definitely need a dedicated table with a vac set up as it does dispense the cuttings freely, in other words, everywhere. Should be no problem as I'll get another table like the table saw sets on and make a small box on the back side of the unit to suck everything away. The table moves smoothly when setting to degrees, the end stop is a nice feature and will aid it multiple cut at the same length. The blade guard works very well, as does the lock release and start button. The guard does reduce visibility a little but looks like it could be trimmed up a bit easily, time will tell if I do that. The clamp for the work piece works well and can be used efficiently without locking down but does make holding the bigger pieces firmly a breeze.
    I have only cut a few boards but I do believe it is going to be worth every cent it cost.

    It is always nice when you buy something and turns out good and does what you needed it for. You can never have enough tools.

    FYI, the hold up is I am waiting on the carbon laminate and some ply. The next step in construction is the wings trailing edge, kit call's for balsa but it bows with the tension of the fabric so it gets lightply in the aileron area. I also want to make the ribs to finish checking how the slave rod will fit and function. So until then I am social distancing around the house. Replaced the well station slab the last three days, that was a pain, as I hate pouring concrete. And today I am starting the replacement of another 650' section of fencing. Always plenty to mend being a home/property owner.
