Settings are a very personal thing with gliders but as a start point.

For the new Willow 2 model my suggested settings are-

CG: 108mm. This is a ballance neutal point. 

Elevator- 5-6mm each way (measured at the root)
                    I do not use a large amont of snap flap for my flying style, no more than 2mm of flap with the ailerons mirroring the movement.

Aileron- Measured at the wing tip, 9mm up andf 6mm down.  I have the flaps mirroring at around 25% of the movement.  I have also started to mix in a little aileron/rudder mix to help keep the noce down.

CROW  Elevator 40% down
             The flaps can me set up to come 90degrees down very easily
              Ailerons 40% up

For the Willow 1 here are my suggested settings.
Cg- 100 to 105mm- Feel free to experiment with this but this is a good starting point.
Elevator-  8mm each way (measured at the root),
                                Snap flap 3-4mm (measured at the flap root and constant along the wing).
Aileron-  12mm up 8mm down (measured at the tip)- I've lately been using 9 up and 6 dow for a smoother style.
                                Flap mix 4mm up 3mm down
CROW- Elevator 3mm down,
 Aileron 4mm up (measured at the tip),
Flaps anything 60degrees or more is very effective.
Launch/thermal mode- trailing edge 4-5mm down measured at the root and flat across the wing
Speed mode, 1-1.5mm up measured at the root flat across the wing (you may like to reduce the differential as this point as well

At the recent Champion of Champions race Adam Richardson had me increase the snap flap to over 6mm at the flap.  Worked great in theh turn and delivered 6th place.
If any Willow Pilots would like to send me their settings I’d love to hear from you and get an idea of the range of setting are out there.  The Willow’s characteristics make it great to experiment with different settings.
