Cool shit, like U idea, although why not fill it in where it's not needed. Are those tuttle boxes on the wings?
Hi NorCalNomad!
Yes- I filled empty spaces with foam and carbon.
The boxes on the wings are built to connect wing with fuselage...holes drilled for the wing -1/4 and for the stab-3/16 in.
You can move both-wing and the stab back and forth.
And using washers you will be able to change the angles of attack on the wing and the stab as well.
By the way, rotating all system with the housing plate and the hydrofoil 180 degrees, will give chance to try canard -for sure you will need to play with angles and etc.
Cheers! :bye:

Nice! Good job.

I like the U Channel fuselage ... low tech and looks effective. Is that stainless steel?
Thank you juandesooka!

It's tempered Aluminum 6061
And it's 2 channels- please look at my sketch...

Nice rookie build Lev! What materials did you use for the board, wings, fuselage? More importantly, how does she ride?

Interesting.

I have a couple of thoughts.

Mast seems real short whats its length?

I worry the channel and bolt heads/nuts will provide turbulence and reduce performance. Perhaps consider filling in the channel.
I also wonder if the rear vertical stab is too far forward to be effective? You could mount it directly above the rear stab.

Is the board also used without the foil? if not why install fins?
Hello plummet !

1.I've built 3 masts- 550, 750 and 950 mm long;
2. All empty spaces in both channels I filled with foam;
3.For the front bolts and nuts, I'm planning to make a cover...;
4. Made the board with fins in purpose - I could use it as a regular board...
5. The vertical stab can be moved back- no problem :jump:
Fins can be removed.
Thanks for the feedback!
Sounds like you are onto it then.

Whats you aoa of the rear wing compared to the front?
Can you put the rear wing on the top of the fuse? Why? When the rear wing is on the top of the fuse the water forces pushes the wing down onto the fuse. With the rear wing on the bottom the water force is trying to tear the rear wing off the fuse. Its a lot easier on the bolts and less likely chance of having the rear wing fall off if on top of the fuse.
