If you want to make standoffs...

Let's just say you're building a foamy and you are using the ubiquitous HS-55. You'll use the arm with the larger holes, and cut the unused side off. Use the side you just cut off as a standoff. Just drill the outermost hole to accomodate the diameter of the pushrod. Glue the other end of the servo arm to the fuselage. You'll simply cut it to length and VOILA! instant standoff. Weighs about nothing. Looks very pro.

Did I explain that well?
