REFLECTOR: Slip String (or Aileron Trim)

[Ron Brown]

While I have my plane apart, I took a look at my aileron trim (slip string):

I have 2 1/2 wraps on the spool, I sprayed it with belt dressing from the 
auto parts store back when I built the plane, and the springs are slightly 
stretched when in the center position (perhaps 1/4 to 1/2" from the relaxed 
position).

When I take the ailerons to full left or full right, the string might slip 
about a 1/4 inch, most of the time it doesn't move at all.  If I don't take 
it all the way to the stops, the string doesn't slip at all.  As far as I'm 
concerned, the factory stock set up works fine.  I do use it from time to 
time depending on if I have a copilot, or just a tweak to pick up a heavy 
wing.  It certainly works well enough that it is useful, cheap, and since it 
isn't needed often (not like the very important pitch trim), I'm happy.
