REFLECTOR: servo speed control

[Andrew Ellzey]

Lou,

Have you checked the voltage that you are getting out of the SPD-1? I designed my own speed controller and found that it took an output of around 4VDC to see a change in speed of the standard Velocity elevator trim actuator. I'm not flying yet so this is in an unloaded condition.

I recently installed a SPD-1 Servo Speed Control which I purchased from ACS. The unit has three wires . One for power from 1 amp fuse, one to feed power from control to the DPDT switch on my control stick, and one to ground. I am very sure that I connected it correctly but it made no difference in the speed of my liner actuator speed. After adjusting I found that in the lowest setting, my liner actuator would not move. In all other settings the speed was the same. Has anyone else installed this or something similar?
