Servo arm balls.
When using the "longer stand-off" ball on the Align servo arm can you still get the nut on the back?????
Mine do not clear the arm to accept a nut.Is the usual?
I am using the longer ball to get the linkage more upright.
I am also using 16mm hole BUT will avoid hitting servo by using less pitch,newbie.I think 10+/- as been mentioned when completed correctly with 16mm hole.

Pro Anti,

If you are not comfortable with thread only in the arm a option is to get a bag of balls with the 2mm hole in them. I got a bag from Heliproz. You can use a 2mm bolt as long as you want with a stack of 2mm flat washers for standoff. I had thought about using aluminum arms and threading them for the ball stud but the fellow at Heliproz recommended against doing that as their experience is the studs get loose in the aluminum even with loc tite and they stay tight in the non-metalic ones. I have the studs screwed into my arms with no backing nut with about 10 flights and so far they are staying tight.
