Sure, Hi,

On elevators they were JR 32 something. Used them on my Bandit ARF too becasue they were the only ones that would fit, and on a Tamjets F-16. I now have HS-5625MGs, they provide a little bit more torque if you use 6V.
Ailerons I use 5245MG, so easy to install. I know people who have used Hitec thin wing servos succesfully on ailerons, they are barely 60 in-oz. I'd only use those if you are 100% sure you will never use ailerons as flaps.

Then for rudder I use JR Thin Wing digital DS-398. You could go HiTec, thin wing but I'd rather have the extra 20 in-oz since I do use rudder a lot, and at high speed.

This is a proven combination, that doesnt require a lot of power. I probably use between 250-400 Mah per flight, including a power thirsty EV5A valve.

Keep em light, fly em right. ;-)
