Adjustable Retract and Door sequencer w/Display -- End point Adjustment?
Against my better judgment I got one of these:
Servo delay for Flaps or Landing gear.
The main function of this controller is to slow-down the movement of the servo.
It can be used for landing gear or flap of aircraft model, or other applications.
Starting position and movement speed can be adjusted.
Dimensions: 35 x 12 mm
Working voltage: 5 V
Time adjust: 1 - 14 s
Weight: 3 g
It’s of absolutely no value to me!
If there was a zero point on speed adjustment it might have worked since in can adjust one end point.
But it does not work around the center position – it drives a servo to either end ONLY.
And, is of no value with a retract servo for mechanical retracts (i.e. my Mustang) or w/“servoless” retracts (my B-17).
I still haven’t found what I really like to have ; does anybody have the instructions for one of these?
Adjustable Retract and Door sequencer w/Display:
This Retract/Under-carriage door control unit offers adjustable delay sequencing between your retracts and servo powered gear doors for both the up and down positions and also end point adjustment for up to 3 servos. Simply plug into the gear channel of your RX, plug your retracts and doors into the unit and set up via 4 buttons on the reverse of the sequencer which also features a large, easy to read LED display.
Input: 1 servo Channel.
Output: 3 Channels (retracts and 2 x doors)
What I really want to do is have something that will allow me to adjust end points of a servo when used with a dumb TX?

First of all, those servo speed slowdown units will not work with a retract servo. Some of them can delay the actuation of the servo if you want to sequence. But a retract servo is non-proportional, its only available positions are full left, full right. You will have to use a regular proportional servo on your retracts to get the speed control function.
Exactly which transmitter are you using? Some of the non-computer radios have their reversing and possibly also end point adjustments under a cover.
