REFLECTOR: Sparrow Strainer

Just did a test flight after reversing the strainer and I want to say

THANK YOU STEVE KORNEY!  What a difference.   Before, I ran out of trim

at 155 KIAS.  Today I got up to 172 and still had trim left.  Also,

understandibly, there is less trimming needed when transitioning from TO

to cruise and vice versa for landing.  Also landings are easier, I guess

because the strainer is continually lowering the elevator a bit as I

slow down.  I did not notice any difference in pitch stability.  This is

definitely the way to have the strainer installed.

I'm wondering if I'm the only one that is a bit 'troubled' by this.  I mean
"Which is it?"  We're not talking about adjusting things a little, or
changing the angle of incidence - we're talking about completely opposite.
The factory is saying put the airfoil on inverted so it works against the
trim, and you guys are finding that it works best for the airfoil to be
right side up and working to assist the trim.  It seems to me this should be
more than a matter of personal preference.  It seems somebody has it
backwards; it seems an issue that needs some resolution.

 

I guess I'll just try it both ways and see which I like better.  Now that's
science (or is that sarcasm).
