RE: servo help
I've used the little Cirrus (4.9 I believe) with great success. They are a standard servo design. Stay away from the Micro Joule (Micro Junk). It is a novel idea to be made in a Swiss watch lab, but not in Taiwan mass production. Went through 5 to get 1, I guess, good one, and gave up, as I was about to get shut off on the returns by my LHS. For the difference of less than 2 grams, it is worth sticking with a standard servo design.
