Really Old Flaperon System
 

I posted this in kit building but I was given an old Corsair kit built plane that was built way back when. It has the strangest aileron/flaperon system I have ever seen. I have it all set up and working now but just figuring it out was A lot of fun, I have never seen anything like it, go take A look at what it took someone to come up with before computer radios.;)

Is yours a two-servo sliding tray or a two-servo tipping yoke? ;-)

As you say, ccomputer radios only add ease, not additional features. God Bless digital trims, however.

I went over and looked: tipping yoke. The other way to do it is to make the aileron servo in a sliding tray and a second servo pulls or pushes it for flaps or spoilers as needed.

You should have seen some of the mechanical solutions for V-tail mixing. :)

I had to study the picture for a minute or so but it finally figured out how it works. Pretty cool actually.

Charlie, I really didn't have A clue as to what it is called until you asked the question and gave me the name.
Chuck, it didn't have any servos in it when I got it, I had to stare at it and move things around for A while before I figured out what that second servo did. I'm sure if anyone else was around at that moment they would have seen the light bulb come on in my head.
A sliding tray, good lord, I would have just rather come in on A longer approach and hot!!
V-Tail before computers, not me!!:D

Grey Beard, there is always a few ways to get from point A to point B. Today it is electronic. Yesterday, it was mechanical. Mechanical servo mixing was state of the art some years back. Just like things we consider to be bare minimum requirements today. Expo, end point adjsutment. Difrientual, Mixing. you name it. All of these had a mechanical heartige, but they had to be designed around an individual air frame. Todays electronics allows us to custom fit a Tx to our plane. Vs the old days when you had to custom fit the plane to the TX.

Not unusual at all. It is a DuBro product and still an excellent way to do Flapperons or a V-Tail:

Dang if that isn't something. I have been building sense 1958 and into RC for about 12 years now and I have never seen anything like this. How cool is that, it's something still being made and sold.

I still have one bought in the mid 70's. I didn't like it much as the geometry is not right- the aileron throws are uneven at full elevator or flap deflection.
For elevons I prefered to use two servos - one sevo on one aileron in the aileron channel one servo on other aileron and elevator channel. Turn and hold TX at 45deg.
Full forward/back /side stick moved both sevos to max travel. A bit difficult to describe but an easy solution to a difficult problem at that time.
