Re: Wing profile info for backyard hydrofoil builders

Hi Eric, Here are results for the new bigger size. It's got some size to it at 2260 cm^2 and still getting surprisingly low drag values. NACA2405 gets the best overall result, but NACA3505 also puts in a noteworthy result (With less drag at the start but more at the high end than NACA2405). Capture...

Re: Wing profile info for backyard hydrofoil builders

Hi Eric, If you are increasing wingspan or chord by a lot, then let us know the final wingspan and chord size you settle on and I'll rerun the profile selection to check best option for that size.

Re: Wing profile info for backyard hydrofoil builders

The new trend seems to be for the front wing to be more arched and the wing tips turned upwards. This apparently allows the wing to breach without loosing control. tks windmaker in which brand did you see what you are saying for me to analyze? best regards Eric F-One, Chubanga, Mike's lab etc BTW w...
