Interchange Airtonics/JR servo arms

[ronlock at comcast.net]

Ive found it is a mixed bag.  Almost all will bolt on, and some 
Airtronics/JR servo and arm combinations fit properly.  Depending on 
particular model of servo and brand of arm, you may find a very slight 
bit of slop. It may show up as a slight trim change that that won't go away.
