JR NES 4000 servo

[davel322 at comcast.net]

JR made several "super servos" - the ones suitable for pattern were the 4000, 7000, and 7100.

The 4000 is not a low profile servo - it is a "standard" case - same as 4031/4131 - slightly different from the 8101/8231/8417/8411 which have the wider spacing on bearings of the ouptut shaft.  The 4000 came with nylon gears.  Very good servo - in my opinion, performance is equal to an 8231 - but it is more power hungry than an 8231 as others have noted.

The 7000 "super servo" is low profile servo (with nylon gears, same case and gears as 7005).

The 7100 is another low profile "super servo" which is basically the same as the 7000 but with metal gears (7005 gears could also be retrofit).

Regards,

Dave Lockhart (Team JR)
