  For those of us unfamiliar with pulling servos apart this would be an excellent topic to have a step by step how-to (with pictures) on either a web page or an article in the K-Factor. 

  I'd like to covert my 9411's because they already have play in them after about 140 flights. I've not pursued it yet because I don't know which gears to replace or if there are any "gotchas" I should be aware of when making the change.

    Nat,

    The conversion is to leave the metal output gear in place. So the gear that the servo wheel attaches too is still metal all other gears are nylon. And the standard servo comes with a Nylon gear off the motor already and this gear is left in place.

    I have been running these servos converted for 2+ years now and I have tons of flights on them...We are talking over 2000 flights on these servos converts....Lots of snaps and lots of abuse.

    I have never had a gear strip in the setup....Servo pots wear but not a gear go bad...I don't think you can convert the output gear easily to nylon because of the way it is attached to the pot and the bearing. I'm sure you can get the bearing off the shaft on the output gear and then it might work out..I also will add a little white grease like the servos use...Also in a  pinch I have used petroleum jelly too....Probably not the best choice but it worked.


    My question is what gear(s) stripped?

    I am very curious as I have had nothing but superb luck with this setup. My opinion this is the absolute best aileron servo setup I have ever used. They are fast strong and light just over 1.25oz each.

    Let me know if I can help you out.

      I had two DS9411's coverted to SA . A gear , or gears, stripped in both with relatively no torque by hand. They could have easily crashed an airplane. Does  the stock SA have all plastic gears, or only one or two ? These were converted to all plastic.
