[NSRCA-discussion] ] servo question again

If they have standard 8411's, you could just get the nylon replacement gears 
and roll your own SA.  I did that with all the 8411's I used to use on the 
IMAC stuff I had.  Another option might be to pick up the 8311, which is an 
8411 with a different motor. It has slightly less torque, and is plenty 
quick. It was a re-tooling to work on heli tail rotors, which were burning 
up the 8411's sometimes with all the incessant dithering that goes on in 
that application.
