Servos

[Nat Penton]

I still dont know if the 9411SA comes with a plastic output shaft. I do know that the metal output shaft has a plastic "bushing" that is inserted (pushed with some difficulty) into the bottom of the metal output gear and the bearing is installed on this bushing.

  I remember that the reason you left the metal output shaft in place is that you can't get the bearing out of the bottom of the gear. Does the 9411 SA version come with a plastic output shaft?  It is not shown on the Horizon site.

  Also, is Troy back on the list. I only see his posts if someone lese replies to one and includes his notes.

  Regards,

  Eric.

  On one servo I replaced all but the motor gear with the returned metal gears and ,like Troy says, it was somewhat difficult replacing the servo arm gear and, Jerry, everything "feels" ok. The two smaller intermediate gears had missing outer teeth. The other servo I replaced all but the motor and servo arm gears with the returned metal gears and , Jerry, it feels super . The inner gear on one of the intermediate gears was missing a tooth or two. It seems to me this is the logical way to go on future conversions and I believe this is what Troy said.

    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.
