Can one convert the 8411 to 8411SA by replacing the metal gears with a
plastic gear set?

  Yep, the 8611or better yet, the 8611A is another good way to go, though I
am using up available inventory of 8411's.  BTW, 8411's can often be had at
a bargain price, since they have fallen out of favor which much of the big
gas crowd.  They're a very good servo for Pattern use once converted to SA.
A major complaint in big gas use was that the metal gears wore very quickly,
which often contributed the the other big complaint that they would
oscillate.  There used to be lots of fun discussions about how to set things
up to make that stop happening.

    Just put an 8611 in there and no worries.

    I got one these and am going to try it on the rudder of my new ship.
Can you say OVERKILL??

      It does help in high stress applications. I use them on the collective
servo  and elev. servo in 60 size heli's. The 8400 series JR servo has the
bearings spaced farther apart than the older 4000 series which helps reduce
the side loads.

      The ball links on the JR set are a little tight and need to be free'd
up a little to reduce drag. I haven't bought any in several years.

      The 8411 should hold up well on a 2M pattern plane without it ,
however it is piece of mind when hooked to a big rudder...........John G.

        Do we really need this output arm when using JR 8411 in the rudder
(pull-pull system)? As far as I know, the main output gear is supported by
two ball bearings.

          I don't think JR makes them anymore but here is one that is the
same thing by K+S for Helis:

            Does anyone know if these are still available?  These were a
rectangular metal bracket that went around the servo, over the mounting
flanges.  This bracket held a post with a ball end, which connected to a
ball ended bolt for the servo arm, via an arm with swivel joints at each
end.

            Thanks
