[NSRCA-discussion] ] servo question again

[DaveL322 at comcast.net]

JR stuff is all rated at 4.8v, and often there is a 2nd rating which is at 6v.

The 8417 is indeed 82 oz/in and .10 sec on 4.8v.  Changing the gears to an 8411sa changes the ratio a bit, yielding about 100 oz/in and .12 sec.  Running at 6v it is about 120 oz/in and .10 sec.  I've been running all pattern stuff on unregulated 5 cell (average voltage is around 6.5 w/ "bump" charging between flights) and 6.5v regulators for many years.

Regards,

Dave Lockhart
