I always wonder if the front wings are at 0° AoA (in line with the fuselage) and the lift will be greated by the Naco profil itself. Or is it usefull to give the frontwing already an 2-4° AoA ? I am more interesstet in an foil for pumping . Would be also great if someone has experiance what kind of Naca will work out. Hearing a lot of diferent things at the moment. Naca 63 210 or 6412

If the hydrofoil is used on a windsurfer, is there any difference in how much angle of attack is needed?

Hi! I am working on a electric hydrofoil board and I would love to hear your thoughts on the AOA of the rear wing when the forward force is coming from a propeller placed just above the rear wing. One would think that the angle would be the opposite from when a kite is used to "propel" the foil. What do you think? You can se the build on Instagram @wildtech.eu. Thank you.
