What's a JR 9411SA servo?

[Troy Newman]

Mike,

they are the same specs as a 9411....they are a nylon conversion just like the 8411SA. The price difference is because the cost of the metal gear train as opposed to the nylon gears.

Basically many of us have been converting them ourselves using 911 gear sets and leaving the metal output gear in place. Now JR has made this a standard offering and the servos comes new this way.

The part number is JRPS9411SA. 

also this same conversion thing has been done with the 3421 to give a 3421SA.


Now some of us are making a conversion to the 8417 with the 8411SA gears. This one is not offered this way stock for a couple reasons. The gear change out changes the specs on the servo. It slows down and has a little more power. So its not a direct Metal to nylon conversion. In the case of the SA servos (8411SA, 9411SA, 3421SA) these servos all retain their same specs except the weight changes slightly as the nylon gears are lighter.

These 9411SA's are absolutely the best aileron servos I have ever used. This past weekend I flew Tony Frakowiak's Electric Partner and he used these same servos on ailerons and dual elevators and it was as good of setup as I have ever flown.

   I've been following the posts about voltage regulators and Troy mentioned using JR 9411SA's on his ailerons. I saw the specs on the 9411's but I didn't see a listing on the SA's. Are they cheaper than the 9411's just as the 8411SA's are $15 cheaper than the regular 8411's with metal gears? Right now I use 8231's on my ailerons but I need new servos for a second plane and thought these might work better. Any insite or thoughts on this are appreciated. Thanks, Mike
