Armstrong TTF (Titanium Trim Fairings)
Armstrong's state of the art rear wing configuration incorporates easy to change, honeycomb Titanium Trim Fairings that allow riders to fine tune the UNI Tail Wing to their personal feeling.
Armstrong supply two Shims (TTFs) with each Foil package. One Zero degree and one +1 degree
To personalise your ride additional angles are available.
The Titanium trim fairings set the angle of attack of the tail wing. We use -2 degree, Zero degree and +1 degree trim options. These adjustments work in conjunction with changing the front wings, the fuselage length and the required use.
-2 Degree: For learning, larger boards/people and windsurf freeride. Tail has more downforce giving front wing more lift at lower speeds and better Yaw (directional) stability.
Zero Degree: is best with the CF800 wing at higher speeds kiting or tow surfing and good all around with the CF1200 and CF1600 wings.
+1 Degree: For more top end speed control on all wings and better pump for advanced riders looking to maximise glide and to Down Wind Foil. During a drop or speed spike the +1 helps keep the wing in the water and adds control during turns.
