    Help Please CGR9183 Gear Servo

    I have a DX5E Transmitter and a AR500 rcvr. It has a switch on/off for the landing gear control. What do you recommend for a gear servo?

    That depends on how much thrust and how strong of gears you need on the servo.
    Alos some retracts need a 180 deg throw and some only need a 90 degree throw.
    It really depends on what you need for the retracts.

    Here is one retract specific servo:

    44x23x25mm, 1.23 oz. weight. 92 oz./in. torque.

    I believe you can adust the throw to what you need.
    Looks like that servo from HiTec will be good.
