okay - this is thread creep, but while you are wiring those things, another question is how to get 12v power to them without involving a cheesy 24/12 power converter in the path?

 

Colyn,

 

I used “standard” electronic 12v converters, available at Radio Shack or any electronic parts store. They typically take any 12-40 volt DC input and output 12 volts DC. They are very inexpensive and about the size of a dime. Although they are available in higher power ratings, those typically available at Radio Shack are rated at 1-3 amps. I tested these and found no problems all the way to stall current with the Ray Allen servos. While one would theoretically be sufficient to power all servos and associated indicator lights, I used a separate one for each application under the theory that at most I’d lose one trim system, but not all of them. Ditto for the indicators. I also fused these at 1 Amp on the input side and this seems adequate.

 

BTW, these are the same units MAC/Ray Allen use in their “voltage converter” boxes…
