Tips from the Flying Field: Aileron Differential

Tips from the Flying Field: Aileron Differential

What is aileron differential and how your model can benefit from using it? Senior technical editor Gerry Yarrish explains this important mix in this online video. Programming this feature into your transmitter will make your plane fly smoother and more precise while eliminating the need to coordinate aileron and rudder input to counter adverse yaw. It’s an especially useful mix for biplane fliers.

  1. Very interesting and useful ! Thank you !
    I suggest it could be also interesting to show, in flight with your model, what’s the diference between “without” and “with” the differential.
    Anyway, congratulations for your tips !
    And Merry Christmas !

  2. Very helpful. Thank you. If you ever want to take this presentation to the next level, some footage of flying with and without differential would be really terrific.

    Merry Christmas and Happy New Year!

  3. Flat bottom airfoils benefit more from differential than symmetrical airfoils. A classic Sig Kadet Sr with ailerons for example does very well with almost no downward aileron movement and plenty of upward throw.
