[NSRCA-discussion] Metal Servo Arms

[rcmaster199 at aol.com]

I would be very careful about an arm (any material type) that doesn't seat fully onto the servo output spline. Although a metal output spline on the servo may not have the problem, I experienced a problem a while back with the arm not seated fully on a plastic output spline. The spline twisted apart. The retaining screw simply didn't go far enough and servo torque twisted the unsupported plastic.

It’s not unusual at all for those H9 arms to be really tight.  Usually you can work the arm off with a pair of channel locks by rocking it gently as you pull it away.  Just brace the case top close to where the bearing underneath is seated and you won’t hurt anything.

I bought some Hanger 9 alum servo arms and when I put them on they are VERY hard to get to pull down on to the servo. Is this normal? They don’t go down as far as the plastic arms do. They are stamped with a J on the bottom so I assume they’re made for JR servo’s.
