Thanks Troy for the feedback...extremely helpful. My current thinking is putting 8231 servos on the ailerons and doing the rest as I originally planned (8417 elevator and 9402 rudder). If I'm unhappy with the aileron speed (the torque is equivalent), I'll put in 9411 servos.

Out of curiosity, why the 8411SA for rudder vs. the original 8411? I presume it's because the plastic gear train will have less backlash and wear better, but I've normally used metal gears on my rudder servo (I fly off a grass field). I might give the 8411SA a try on a future plane and see how well it takes the grass field abuse.

I've never really worried about the throttle servo...I usually use what I have laying around, typically a standard BB servo. What advantage does a high end servo have for throttle (or is it primarily that you have some of these lying around)?

I hadn't heard that some many Futabas don't like 6V. I've run a number of them (and Hitecs) on 6V without any trouble. The 9402 packaging actually specs it out at 6V, so I would certainly hope that it is 6V capable...

Thanks again!
