I hope this is a simple question but, how do you get the increased control throws for 3D? On my first two planes I used a 1 1/4 inch piece of plastic as an extension on the ailerons. However, I have noticed that a lot of folks use the half inch servo arms. How do I get the required throws using these? I have a Futaba 6EXA and have already set the EPA to the max of 120%. The control rod is connected to the outermost hole on the servo and is connected to the inner most hole in the control horn. Thanks.
