yaw stability

I rode a friends LP foil today and after getting the stabilizer to 3 degrees it is riding well but it felt crazy wiggly on the nose, just a weird uncomfortable feeling...one of those weird feelings that draws you into it and you try to investigate so I just wiggled the nose back and forth, which is ...

Foiled behind a boat today!

We have little wind lately so we foiled today behind a boat. Holy shit was it tough in my opinion to get up. Once up it wasn't too too bad, but you end up almost perpedicular to the motor which still doesn't make sense to me b/c how are you getting pulled if you are perpendicular to the motor...weir...

Mast angle ahead of fuselage

I've seen this on some hydrofoils and wondering what the thought is. Is this to overcome the issue with the angle of the rocker on the tail end? I'm thinking if the rocker is basically a 2 degree angle towards the back the mast needs to be angled similar to adjust for this. https://image.ibb.co/cHtS...

Re: how do you sand your wings...?

I'm crazy confused on sanding...if you keep sanding month after month you are going to eat into the epoxy too much. Are you sanders spraying the entire mast, fuselage, and wings with some type of spray paint then sanding?

Hand drags getting yanked

Here's were I'm at on hand drags...2 months ago I was nailing them on a 14m in flat water in 18 knots going either way. Landed dozens of them. Felt like I had that trick in the bag so I tried them the last couple sessions on this cold front. This time I'm perfectly powered up, but in some chop but n...

Re: 3D printing of kite plastic parts: low friction sliding ring

Man, I was reading this thread and was surprised at all the emotions. Chill out people, if some dude post stupid shit, just don't reply. Jaystore, If you want me to print some things out and test them I will for a new dynabar :) I've been printing for 5 yrs. My opinion is any typical material will ...

Re: hydrofoil at max speed limit

Obvious beginner question: What happens when you push a foil beyond its maximum speed? Slowboat, The wind speed and breaking strength of the foil will determine the max speed. I'd recon the foil, board, or human bones break at the max speed. I think what you are asking is what gives out first after...

Re: Dihedral stabilizers

Speaking of sideslip, lol...so I'm wondering a couple more things...A plane sideslips, BUT it doesn't have a massive fucking kite pulling it downwind. So is it possible a hydrofoil is sideslipping in the opposite direction a plane does? Furthermore, attack angle is based on apparent wind and chord.....

Re: Dihedral stabilizers

Not sure if this answers your question, but what I did here was make a dirty model with an angle of attack on the front wings and negative on the back. Both wings have dihedral and anhedral so you can see the theory. I'm still learning so this is new to me. Anyway, from what I've read in planes if t...

yaw stability is the duty of the mast
teg,

Thanks...that brings me to another question I always had..with such a large force created by the mast is the small vertical stabilizer on some older designs below the fuselage necessary from your experience or are they just additional drag?
