Re: How to turn a hydrofoil - and what is YAW ?

I don't see any misuse of terms.

If many with knowledge says I do, that I am wrong and misleading, I would of course reconsider.

Re: How to turn a hydrofoil - and what is YAW ?

I still say you are wrong Mossy, and can in fact show that planes can turn fully around with wings perfectly level because of horisontal COE coming from the fuselage can be well in front of the rudder so the resulting sideways force acts just like banking and pulling the elevator, but no reason to w...

Yaw is not what turns a hydrofoil, rolling in the direction of turn redirects the upwards lift vector towards the inside of the turn and induces the change of direction. Just like stepping on a rudder pedal in a plane doesn't change direction, only points the nose in a new direction. In a plane whe...

Re: How to turn a hydrofoil - and what is YAW ?

Thank you :D - and I am sure you are right Peert, it origins from sailing of course, even if used most often in aviation now, my mistake. My background in flying and aerodynamics/design, and the fact that when you google it today (just checked) yaw is mostly used in aviation, made me erroneously thi...

How to turn a hydrofoil - and what is YAW ?

Hi, during the years this question has been put many times, very understandable as it DOES NOT turn like you are used to.

Re: Balance question - before I get my drill out....

Unless I'm mistaken I see two mast mounts already drilled and you put your mast in the wrong mast holes they need to be in the other set near the front. looks like there are 6 mast holes drilled so you can move the mast back where you have it or took the front holes where it should be Agree fully, ...
