[NSRCA-discussion] 8611 on rudder

[brian young]

I  also noticed when switching from the 9Z to the 14MZ all the servos buzzed less, rudder oscillation with the 8411sa was not an issue on the 14MZ.

So spend the extra money to get a 14MZ     ;-)          ........if ya dont already have one........

I agree with Dave. Also, the 8411 works fine with the 14MZ whereas the 8611 is prone to oscillation (suspect a mismatch with the 14MZ refresh rate). 
 
 OTOH, the 9155, BLS351, & 9156 (in order of power) Futaba servos all work well on the rudder @ 6v. I've  also noted a different "feel" with the brushless servos that, I suspect, is a result of motor rotor mass. While the total transit time of a brushless & coreless servo may be the same, the brushless seems to start slower which seems to result in a bit smoother feel. I also don't see any benefit to torque above 200 oz - in, but this may vary with airplane design.

I prefer the lighter weight, tighter geartrain, and more aggressive center of the 8411sa.  I’ve not found the added torque of the 8611 necessary.
 
If oscillation is a problem with the 8411sa, the 8611 may fix this – but the center will not be as aggressive (but it may not be a big enough difference to notice depending on the specific plane and specific linkage system).
 
Regards,
 
Dave

I'm interested in feedback from those who are using the 8611 or 8611A on a 2M rudder.  Is that extra torque as compared to an 8411 class servo really buying you anything? I'm always reluctant to go to a metal gear servo, although the 8611 is pretty low on slop as MG servos go.
 
Thanks
Ed
