[Keith Black]

Thanks for the info. Dave and Wayne, that's good to know.

As it relates to the 9411, what nylon gear set can be used with these? When I look at the Horizon site I find much the same for the 9411SA as for the 3421SA, gear replacements are about $20 and rarely available.

Thanks,
Keith

    Keith,

    Metal gears are expensive.

    The 3421 comes with all metal gears while the 3121, 3021, and 321 all come with nylon gears (save the pinion on the servo motor) - all the gears are interchangeable.

    The 3421sa has the metal pinion and a metal output shaft - the 3 gears in the middle are nylon (from the 3121, 3021, 321 servo).

    If you buy -
    - 3421 gears - they are all metal (and expensive).
    - 3421sa gears - you will get the metal output shaft (expensive) and 3 nylon gears.  
    - 3121/3021/321 gears - you get all nylon gears (cheap) and you will have to move the ball-bearings on the ouput shaft from the old metal output to the new nylon output - or just re-use the old metal output which is I believe what Troy is suggesting.

      Troy, if that is the case, then why does the entry on Horizon's site marked gear set for 3421SA (JRPSG3421SA) show "Not Available". Also, it is marked with a price of $18.95, not $3.95.

      Go to the following link and look at the fourth entry down and you'll see what I'm referring to. A while back I had some 3421SA's in for service and they kept them for several weeks because the gears weren't available.

      If you're correct on the gear set then that's awesome, not only are they available but much cheaper. Perhaps they're so new that it's just not general knowledge in the service department, but that's hard to believe. BTW, the guys I talked to at Horizon couldn't explain why the replacement nylon gears were so expensive compared to the 8411SA, maybe you're onto something.

      Thanks,
      Keith Black

        Brian,

        Part# JRPSG321

        Shows as In Stock on the Horizon Hobby Website

        http://www.horizonhobby.com/Shop/ByCategory/Product/Default.aspx?ProdID=JRPSG321

        These are the gears to use. I leave the metal output shaft and replace all the others below it to nylons. This is the way a standard 3421SA comes out of the package.

        Hope this helps

        Troy

          Anyone know where I can get some gears to convert my 3421's to 3421sa, they seem to be unavailable everywhere I call.
