[@polyarthus4282]

Maybe you could design a simple RC rescue vessel to push your stranded experimental boats back to shore ? Something small enough to bring along with you without it being a hurdle. And simple and proven enough so it doesn't require a second rescue vessel to rescue your rescue vessel in case of an accident !

[@halfeld]

Heck, make it bigger, give it a solar panel and just leave it a few dozen meters off the shore in station keeping mode in between tests :p It would be a cool tangent on your episodes... Will it be there still? Not? Plus, whenever it fails, that's an extra search and rescue episode!

[@RandomBogey]

When I was a kid, my dad and his RC friends were into boats for a bit. My dad had an RC racing boat that would die in the middle of the water when it ran out of fuel. So he had a cheap Walmart RC wave boat with a length of rope tied to the back and a fishing bobbler on the end of the rope and he’d use the Walmart boat to loop around the racing boat, snag the rope on the rudder, and tow the racing boat back to shore. Some of the other guys had a fishing pole with tennis ball tied to the end of the line so they could cast out over the boat and hopefully snag the tennis ball on the boat as they reeled in and they could pull their boat to shore. Maybe bring some nylon rope with a tennis ball with you for these boat experiments so you don’t have to wait for it to float back to shore or get wet swimming out to it, assuming it’s in range... Or use a drone to drop the line over the boat then pull it to shore

[@eugenebebs7767]

Question: Why do you use airscrews for propulsion? Wouldn't it be better if you put the propeller underwater? (with chain drive or smth)

[@olliefoxx7165]

Perhaps the underwater foils cause propulsion issues for the prop? The design doesn't really have a place for traditional prop, hence your suggestion. So, I don't know, good question.

[@ezrarichardson279]

Because it’s easier to not get wrong. And he already has a bunch of those motors and stuff.

[@bob2161]

Ollie and Ezra, you're both correct. Getting the power from a motor that is in the boat, to a propeller on a foil that is suspended separately from the boat, is a considerable challenge, with a number of possible points of failure. Using an air drive is much less complex, lighter, and more reliable. Of course, it doesn't hurt that he probably has many suitable motor and prop combinations just sitting around his shop.

[@BJETNT]

Dude, use at least PET-G for your functional parts! PLA will soften in you car on a warm day. Since you've got an enclosed 3D printer, you can use ABS, or even Polycarbonate, though those will be more challenging to print correctly. Awesome work as always!

[@NithinJune]

I'm excited for part 2!

[@MrJdsenior]

To retrieve my RC boat from the shore I used to carry a large fishing pole with a good spinner reel and one of those nerf footballs attached to the end. If you hit behind the boat on a reasonably straight line to where you are standing you could walk the necessary direction on the shore to get the line over the boat and just reel the football to the boat and bring it all in gently. You would not believe how far you can make that nerf dart go with a very hard cast. It made a good standard line cast look like an absolute joke. I thought the fire was pretty cool. At least you got it on video. You might want to look at micro-balloons to add to the epoxy to make a very light and easily sandable filler. We used it regularly building a Long EZ. You mix it about the consistency of peanut butter, so it spreads easily and doesn't sag when filling. The downside is it requires another curing cycle, obviously. And wear a mask when sanding fiberglass. When it gets in your lungs it NEVER goes away, and it is so sharp it reeks havoc when the lung expands and contracts. It's chemically inert, but so is asbestos, I think, so that doesn't help much. Very tiny strands of sanding 'dust' are quite easily kept aloft for long enough to breathe them. Enjoyed the vid. Nice work. It looks to me like you have WAY more travel than you need on those foils, BTW. Remember that wings operate very differently in air than foils in water, as you pointed out. I think a little pitch change goes a long way. I'm also a bit concerned that the bandwidth might be a bit too low, but time will tell. Great project, can't wait to see it all up and working.

[@maxbennedbk7085]

just a little tip. use heavier hulls for more velocity speed, add a skip to the bottom of each hull, and a fine grill infront of the propeller to catch anny debris and to break up waterdroplets... alldo if you want controlling to be easier use rotary dials so you can lock the ailerons and elevator at certain angles so you dont have to wobble around 50 individual controlls! allso you could call up a friend to help stear it... its a lot easier with dual piloting

P.S. an autonomous sailboat would be super dope, they make RC sailboats already but I feel like making ardupilot depend on a wind sensor and figure out tacking and stuff would be real neat. Alternatively, just deploying sails on the Banana Slug for help on the downwinds would be cool too. Love your work!

[@DingDongDrift]

Just an idea, instead of gluing 3D prints together i melt them together with a soldering iron, it's a much stronger bond, way less messy, but sometimes can require some extra design steps to hide the seams if necessary.

[@TristanCunhasprofile]

A lot of smaller hydrofoil sailboats use a simple physical mechanism to control "flying" height. Like a float on a lever connected to the hydrofoil control. When the boat gets high enough out of the water, the lever drops and pulls the hydrofoil down, stopping the boat from rising anymore. It's a nice feedback mechanism that makes for easy control. You could also do something similar with a sensor connected to the lever, and/or a lever that physically overrides the height control at the upper limit?

[@stevenclark2188]

I suspect, if you were going to fiberglass everything sanding the 3d prints was probably not required. Was that step added to the design later?

[@robertescalante9858]

pro tip for 3d printed finishing -- instead of just sanding, try using a blow torch to lightly melt the exterior (works best on solid bits), and then sand any small bumps or edges! gets rid of any discolored plastics, gives it a great shine, and will make the piece slightly stronger as the filament marks are now welded together a bit better! that, or try using a plastidip or thick/durable paint to fill in gaps easily

[@josedelgado7805]

Do you think an EDC would give you more power/control to come on plane?

[@AntiVaganza]

Just from a quick glance and I could certainly be wrong, but it looks to me like you went for a laminar flow style profile? If so, I would speculate that a more traditional "turbulent flow" profile might do better in these conditions. I would think it would be hard to have laminar flow this close to the surface and with the disturbance from the strut itself? If I am not mistaken, a turbulent one would give you a tad more drag but way more stall tolerance and while the laminar one wil will be less draggy, it will stall earlier and more abrubtly and have more drag once it has lost laminar flow, no?

[@destroyer2012]

[@liamwhelan1687]

There is a sailing boat called the mach 2 or moth (depending on who you ask) this uses a ‘wand’ to control the lift. The way this works is it skips across the water in front of the boat and the smaller the angle of the wand to the boat the more lift the foil creates.

[@BOTmaster15]

Maybe wired question but why wont you change filament to be more temp. resistant? ABS or ASA would stand to around 96C and they are much easier to sand than regular PLA. Or maybe switch to PLA+ or some other different tougher blend (those might be also higher temp resistant - depends od the blend like Fiberlogy impact pla). If it comes to lack of chamber - try Asa or cardboard box.

[@ChilapaOfTheAmazons]

For 3D-printing the foil, it will be *much smoother* out of the box if you print it vertically (standing up), with a brim enabled in your slicer to keep it from falling during printing. 😄👍

[@WoLpH]

Do you need to sand away the ridges if you're going to cover it in fiberglass anyhow? I wouldn't expect them to come through

[@ttpechon2535]

Is that a Sheridan turret on the craft? 1:30

[@AerialWaviator]

Some very cool building techniques with CNC and 3d_print equipment. Daniel is really upping his project experimenting abilities. Do all 3 wings need to pivot? Like a flying wings elevons, think only the front two would be enough. Having the 3rd rear pivot is likely making pitch control much more complex and sensitive. The tip over roll effect is likely being caused by cross control condition of aileron and ruder action, where the boat ends up with sideslip motion relative to water vs forward.

If you were going to fiberglass the hydrofoils, was it really necessary to sand off the FDM ridges?

[@siggyincr7447]

I think you could get a little passive stabilization by putting fixed foils on the verticals about half way up on the verticals. Give them only minimal angle so that leaving/entering the water doesn't create too abrupt of a change in lift/drag. That way the lift automatically gets reduced as soon as the fixed foils leave the water. Might also increase the max speed as smaller controlled foils could still lift it with the fixed ones out of the water at higher speeds.
