Over the past few years I've been using:

9206 Flaps/Steering (MG, standard case, classic hi torque analog, seems to work great here and wont suck down the juice as fast as the digi's)
3102 Valves (MG mini)
9155's ail, rudder (MG, standard case, I think around 200 oz of torque @ 6v)

Just recently I have added the 9156 for use on the ele and rudder. This one is like 340 oz of toruqe @ 6v in a standard case, MG.

The 9155 is an updated version of the 9351 made for aircraft use...

The BLS351 is a brushless version of the 9351. I have friends who use the BLS451's in heli's and rave about the feel compared to the original digital s9451.

Futaba's own alu horns fit wonderfully without slop.
