This device will reduce the speed of any regular, proportional servo. Connect it between your receiver and the servo (or servos) you wish to control for a more scale-like movement of flaps or retracts. Adjustable, it can be set to reduce the speed of your servo from super-slow motion to no speed reduction at all, with an almost infinite number of positions in between. Maximum reduction time for a servo to travel 90 degrees is about 14 seconds, minimum time (no reduction) is simply the normal speed of the servo. Great for reducing or eliminating the tendency of a plane to "balloon up" when flaps are deployed. It can be used to control more than one servo by use of a regular servo Y.
This is the new regulated version that can be used on radio systems powered by any size or type of battery, including 4.8-6.0 volt 4-5 cell Ni-Cad/Ni-MH batteries, and HV (high voltage) receivers that operate on 2-cell 6.6-8.4 volt Li-Po/Li-Ion/LiFE batteries. This unit will NOT reduce the voltage going to your servos.
The video (last image from the list above) shows how one customer used this device to slow the movement of his pilot's head!

Servo Speed Reducer
Plug the Speed Reducer into the desired channel of your receiver, and plug the lead from your servo (or servo wye) into the male servo lead coming from the circuit board. The set screw on the blue trim pot, located near the top of the main circuit board, is used to control the speed of the servo. Turn the set screw fully clockwise (CW) for normal servo speed with no speed reduction, fully counter-clockwise (CCW) for maximum speed reduction, or anywhere in between for partial speed reduction. The red LED indicates three possible conditions: Slow Blinking = No Signal; Solid On = No Speed Reduction; Fast Blinking = Reduced Speed Setting
Please note that if you make any change to the speed setting while the receiver is on, you must cycle power to the receiver (turn if off and back on) for the new speed setting to take effect. This circuit can also be used in conjunction with our Servo Reverser to cause flap or retract servos to turn in opposite directions for correct function. Instructions are included for easy installation and use.
IMPORTANT NOTE: This device will only work on a regular, proportional servo. It will NOT work on a retract-type servo, as they do not recognize any servo positions other than clockwise (CW) and counter-clockwise (CCW). Retract servos cannot be slowed down, even by a transmitter that includes this function, as their design and electronics do not allow it. Check the FAQ page for more information.
