I have a question for the group. I am finishing up section 12 and am to the point of adjusting the elevator trim tab servo. The instructions say to move the servo are through the necessary range of motion (don't have my plans available right now to get the exact wording). My question is what kind of power sources have been used to motor the servo, or what other method has been used? I would appreciate any assistance and suggestions on this matter as I wasn't able to track down much through the archives. Thank you.

Using the white wires, you can run the motor off any ~12v source.

I used my 14.4 volt battery off my cordless drill for this motor and the

flap motor. Just flip the wires around to run the motor the other way.

I used a model train transformer.  Don't be surprised when the cable

movement is asymmetrical.  One of the cables moves out and back if I

remember right.

9 volt rectangular battery works just fine.



Use the two unmarked leads of the servo.  



Swap the leads to change direction.



The servo will stop on it's own when travel limits are reached.



Note: The left and right trim tabs move different amounts.

In addition to the answers you already received, I believe several

people in the past simply used a 9 volt battery.  I think I used a auto

battery charger.

I think you may be able to use a 9V battery.  I'm not sure if that's

what I used or not, but it may have been.  If that doesn't work,

then any old 12V source should do.

Eric,



I picked up a 12 volt 1000 Mah DC power supply from Radio Shack. It was like $20. I have used it to operate and test all the electrical items I have installed to date to include lights, strobes, flap motor, trim servos, trim relays and it even kicks over the main battery relays. Pick up a set of aligator clips and install them on the leads. Very easy and cheap way to ops check things as you go.
