Q: Servo Slow Down Module - I purchased two NF-SD2 servo slow down module 4 to 7 V.  I installed one as directed on a standard servo and it works fine.  However when I insalled the other on a micro retract servo(waypoint w-150MRS) operating mini robart retracts the module did not slow the running time up or down it only delayed deployment.  All connection were correct.  Can you advise.  I have tried this on two retract servos with no success in slowing the run time.
The slowdown unit only works on fully proportional servos. Retract servos are two position, not proportional. If you replace the retract servo it will work.
