I use the RadicalRC .625" offset arm and typically use the second hole from the bottom. This gives me proper aileron differential (zero).
Thanks for your help.
That's just it you get right angles from center of spline to push-rod line by using the last hole on the S3114's longest arm.That will do away with any differential.
Here's a picture it descibes it beter than words.I'm gettig the same geometery by using the last hole on the S3114's.
