Our Servo Reversing Wye with Pot is designed to make the installation and setup of dual servos typically used on flaps and large elevators surfaces a breeze.  It will allow you to use a single receiver channel to control a pair of servos that need to rotate in opposite directions, eliminating the need to use two channels, and eliminating the need for the sometimes difficult mixing required to make them operate correctly.  Installation is simple and straightforward, and this device will work with any brand or type of servo, including standard analog and digital servos, and works with any receiver brand or type.  Since the circuit affects only the signal coming from your receiver, and does not interrupt the servo’s motor wires, it will not reduce or limit the current going to your servos, and will not affect their performance in any way.  It is regulated for use with receivers operating at any voltage, including high-voltage (HV) receivers, and is compatible with radio systems operating at 4.8 to 8.4 volts DC.


The small trim pot near the top of the board is used to make very fine adjustments to the center position of the servo that is reversed, allowing you to precisely sync the two servos so that they are both centered at exactly the same point.  Works on any kind or type of servo. 


The servo's current and voltage are not affected in any way by this circuit, both go straight through with no reduction, only the signal is affected.  Made with heavy-duty 22AWG wire, these reversers are suitable for use with larger, digital and coreless servos that have high current draws.


IMPORTANT NOTE:  New for 2021!  To reduce its size and cost, this device is now produced using SMD parts (Surface Mounted Device).  As a result, we no longer offer it in  an unregulated version.  The price has been reduced from $20 (standard) and $25 (regulated)  to just $16.99, so if you've ordered the unregulated "standard" version in the past, just order this one. This model replaces both of the previous units we sold.  The programming and circuit are exactly the same, only the type of parts used in production has changed.

Servo Reversing "Y" with Trim Pot

  • Pluged directly into your receiver, this device allows two servos to rotate in opposite directions, but still be plugged into and controlled from a single channel in your receiver.  Eliminates the need for more expensive servos that rotate in the opposite direction, and simplifies the often difficult and confusing task of installing flaps.


    This device will eliminate the need to mix 2 channels on your radio just to control your flaps, freeing up that extra channel for other uses. Simply plug both servos into this device, and adjust the trim pot near the top of the circuit board to make the arm on the reversed servo match the position of the other servo precisely.  The pot can only be used to move the reversed servo's position a few degrees, so it may be necessary to reposition the servo arm on the next spline to acheive the best results.  The trim pot allows you to make very small movements to the reversed servo's position independently of the opposite servo, which will make it much easier to eliminate the binding or "buzzing" that can drain your battery quickly and may damage your servo permanetly.


    Note:  This device is intended for use with regular, proportional servos ONLY.  It will not work correctly with a retract-type servo, as they do not recognize small adjustments to their positions.  If you need to reverse a retract servo, use our Simple Servo Reverser available here.
