Dave,
I am currently flying the Sig Cap. It is of course very similar in size and weight to the H9. I just thought I'd share an opinion on something else to consider in servo selection.
Torque is obviously very important, however, a lot of people (me included) sometimes overlook the other equally important characteristics of servos. I used Futaba 9402's all around in my Sig, and the results are fantastic. They center very well, matching surfaces (i.e. ele. halves, ails.) travel at pretty much the same rate, and the speed is great too. When I want surface movement, it happens
RIGHT NOW. These things add up to more precise flying, and thus for me, more enjoyment.
Budget can be a concern. You could outfit a whole .40 size plane for the extra amount that good servos will cost over 3003's, but I know very few people who have just one plane, and IMHO it would be better to have one outstanding plane than 2 average ones.
Choose wisely, the aggravation you save could be your own.
