REFLECTOR: Pitch Trim Spring

[steve korney]

Hi John...

My sparrow strainer arms were wide enough at the leading edge of the airfoil 
to put a vertical slot in the front of the arms and make the front of the 
airfoil move up and down about 5 degrees in either direction...The rear of 
the airfoil
is a pivot point and the front will move up and down... The airfoil is held 
on the arms by a 10/32 screws front and back on both sides... that makes it 
adjustable without having to move the arms...

Best... Steve

Steve,
Thanks.  I am considering a weaker spring and trying to figure out how to 
get there.
By adjusting the strainer angle are you saying to repositioning the airfoil 
to the
arms?  How do I determine what is the right angle?  Could I add a second 
strainer on
the other side?
