Default Question about UCD3D and servos

I will be running 225's on my elevator halves, with 4/40 linkage. A 605 or a 625 on the rudder, mounted under the fuse with pull/pull. Using standard futabas on the ailerons for now, and will upgrade them to 605 or 625s down the road. As for the throttle, and micro or mini would work fine. A hitec hs81 would be great.

Below are the specs on the hitecs at 4.8 and 6 volts. I plan on running a 6 volt nimh pack, not sure if it will be a 1600 or a small 720. Most likely the 1600, just to be safe.

Hope this proves helpful. All the info was from www.servocity.com (who also provides FREE shipping and handling with their orders, no matter the size). They also sell the high priced digitals if you want to spend the extra $$$.
