RE: Ultimate .46 a/c aileron differentials
Good work, but you left out the pictures of the RaidenTech .46 and of course the little jewel from World Models.
As long as you're focused on the little ones, we ought to mention AGAIN the big ones.
You might find the same aileron connections on bigger biplanes. The probability lessens because the bigger they are the more servo strength the ailerons are going to need. So from the BIG ones back down, you'll most often encounter multiple servos with the BIG ones usually having one servo per aileron.
But no matter what size biplane you're working with, if it's got linked ailerons, it would be worthwhile for you to look at the linkage and decide if it's what you really want to fly.
And something to consider, keeping the size in mind.....
With the little biplanes you often see very narrow ailerons. My cute little WM Ultimate has ailerons with 1" chord. That's pretty narrow. And the chord plays a very important part in this connection layout and whether or not the layout will cause differential deflections. Whenever the connection points are close in to the aileron hinge line, the necessity to have a right angle connection increases. And the closer the connection comes to the hinge line, the more displacement caused by using rudder/elevator/aileron horns that have the connector holes "far" out from their base.
If you look at the pictures forestroke gathered, and look at the Pitts (the last picture), you'll see that it has ailerons with probably better than twice the chord as the others. They're probably what? .3C surfaces? Using rudder horns in that linkage won't give even half the differential you'll see on the other airplanes with their ~ .12C ailerons. Now, while the Pitts is the subject, it's actually true that with those wider ailerons you probably WANT TO HAVE the lower horn stand the connection off more. You want the connection point to be above the CL of the aileron the same angle that the wings stagger. Now the deal to consider with the Pitts (and bigger biplanes) is that the connection for the UPPER ailerons should be above their CL. So keep that in mind as well. But all of them can usually be "fixed" easily with the included hardware.
It's humorous to note that the BIG biplanes could actually need the style connectors that are less than appropriate for their smaller brothers.
