REFLECTOR:ROLL TRIM

[Scott Derrick]

Tom,

Mine is setup with a heavy duty string, a lot like good kite string.

You wrap the string 2 or 3 times around the motor shaft, spray the 
string with automotive "Belt Dressing" every annual.

The tricky part is setting up your springs, you want enough tension to 
hold the string tight on the pulleys and motor shaft but not so much 
that when you do full left or right aileron it slips on the shaft.

My advice is to start out with a couple long springs and slowly shorten 
them(both equally) in small increments until it works.
