REFLECTOR: Aerodynamic trim

[steve korney]

Hi John...

Not only that, but you get a lot better feel with less trim spring pressure 
force on the stick...

Best... Steve

Dave,

I had the same problem with my SERG.  I reversed the strainer and now I can 
descend at
200 kn/1000 fpm and still have more trim available.  Reversing the strainer 
is a lot
easier than changing the trim spring.
