What angles are you running? A real quick video looking at what the angles of the of the Armstrong foils and what the shim will change it to. If the video is a bit confusing read below and take it in at your own time and then go and try it for your self.

Hawaiian Sky Rama quizzes Armie Armstrong on the subtleties of shim use with our new A+ system and the Red/blue Polycarbonate shims.
.
Use of shims & relativity.
.
.
No shim equates to -1 deg relative to the fuselage, 1x red shim = 0 deg relative to the fuselage, 1x blue shim = neg 1/2 deg relative to fuselage.
.
.
Armstrong foils front wings have approx. -1 deg angle relative to the fuselage.
.
.
Therefore the offset between front and rear wing is the actual relationship of ride quality.
.
.
Armie summerises that the greater the offset between front wing and tail wing provides more drag and more pitch stability for the foil ride quality. Using no shim would give an offset of 2, (tail -1 to fuselage and front wing +1 to fuselage) the most stable setting. 1 blue shim (+ 0.5deg) reduces offset to 1.5, using 1 red shim reduces offset to 1, 1 red and 1 blue reduces offset to 0.5 deg and 2 red shims reduces the offset to 0 degrees between front and rear wings giving the fastest and most unstable foil quality. Enjoy experimenting with your + system polycarbonate shims!.
