Original Adjustable Wing Twin Fin
You can see it here http://www.wavefin.com/
The side fins are adjustable straight ahead, up and down and that will give you trim, lift and dive.
1. Trim is obtained by having the wing adjusted parallel with the base of the fin.
2. Lift is obtained by adjusting the front of the wing up by one spline from parallel.
3. Dive is obtained by adjusting the front of the wing down by one spline from parallel.
The fin plugs mounts are a high quality FCS fit.
