I must be an electrical idiot. So I want to activate the actuator using a wall wart and a prop controller. When I connect the wall wart power supply to the actuator it acuates but it is humming and it is easier to push down with my thumb than when I have it hooked to the battery pack. It is a 110v in 12v 500 mah out put. What am I doing wrong?

The mah rating is low, and the hum is due to a constant power being applied. Applying constant power at the low mah you have, then factor in pushing the actuator in as its trying to move against you is giving you the hum sound. The higher amped battery isn't making the hum cause well, more power.

Yep, ditto. 500mah ain't enough.

Ok I was thinking that might be the problem. I'll hunt thru my stash. Thanks
