Keep asking eventually you get the answer you want.
If you are going to use a battery backer, why not get one that regulates the voltage too 5volts as well then you can use the 9202's, I think I used to use those in my Helio's in the dim distant past, when assesing play have the servo's attached to the Rx and switched on, its supprising how much play disapears when the power is going through. If you do decied to go with something else, have a look at the Hitec 5625 & 5645 MG's or the equivilant in Hitec, they keep updating them, they are fully programmable from a cheap little unit that plugs into a PC, even a fail safe position can be memorized into the individual servo's.
