Default RE: Super Skybolt ARF

What is my magic rigging scheme? It ain't magic for one thing. Lots of people can't even see what it should be doing in flight compared to the OEM rigging scheme. But if you understand and believe the value of a rule the RC world has preached forever, you will understand the problem with this ARF's rigging and see the value in doing it differently. And possibly consider that you're doing it "correctly". The old rule is right. No argument there. But apply it to the ARF and people seem to think it doesn't matter. Anyway, in a nutshell............

The rigging scheme in the ARF Skybolt gives you 4 ailerons that don't move the same with whatever command you've input to your TX stick. You actually wind up with the bottom two tracking the same but each driven aileron moves different amounts. And one top moves different than the other as well. And there is actually more. Give a left-aileron command and you get a different mix of movements than you get with a right-aileron command. How is this possible? Remember the rules you've seen everywhere.......... Servo arm to pushrod should make a right angle. Pushrod to horn should make a right angle and the 90degree line from the connection point should go through the hinge line. Do you believe there is a basis of truth to those rules? Well, the concepts apply even when the pushrod connects two ailerons.

Here is a discussion on the issue. It was started when I ran into the rigging on a World Models 40size Ultimate biplane. The airplane has staggered wings (don't they all) just like the Skybolt. Both airplanes use the same hardware layout and rigging scheme. Pictures provided........
