fit the plastic output gear just fine. I was trying to get them on 8411sa’s
with the metal splines. I finally did but they won’t go down as far as a
nylon arm. Using a magnifying glass I could see where the alum arm is fully
seated internally. Just looks different than with the plastic arm, as the arm
doesn’t cover the entire part of the splines at the bottom like the standard
arm does. I’m using this on elev with the MK bearing fitting. I’m
going to replace the rudder arm with a H9 as well.<o:p></o:p></span></font></p>

nylon wheel in similar loads and conditions. Using MK
link (which are very close to the plane of the wheel) with round
nylon wheels has been working very well for me. The reason why the nylon
wheel is strong is because the structure is closed. Of course
aluminum wheel would be stronger than nylon wheel.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face=Arial><span style='font-size:12.0pt;
font-family:Arial'>The nylon servo arms are quite adequate when used with a
clevis that applies the force in line with the plane of the arm (typical pin
clevis). Pushrod ends that bolt to one side of the arm move the force off the
plane of the arm and thereby impart a twisting force to the arm. (DuBro type
ball links are the extreme.) Add a bunch of vibration to the normal loads and
the nylon arm may eventually fail - a wheel is a much better choice if one uses
the nylon accessories. In addition to better withstanding the twisting forces
of offset linkage, the aluminum arm is more substantial for screw mounting the
ball / ball bearing end.</span></font><o:p></o:p></p>

seems to be more variation in the spline of the output than the spline of the arm.
(An arm tight on one servo may fit nicely on another.) OTOH, I've found the H9
arms to fit Futaba servos consistently well.</span></font><o:p></o:p></p>

servos. I am not sure why you need the metal servo arms. Usually I
use the round one for aileron and elevator. For rudder I use the heavy
duty arm that JR offers (comes in the 8611 servo). I never have problems
with the nylon servo arms in pattern application.<o:p></o:p></span></font></p>
