Framed up the center section. Good news is that the one guy in the country that makes the fiberglass parts got back to me and the rear wing, turbine tray and front canard are on the way. Also have ordered the motor, mount, drive line and prop. So lots of good stuff going with even a little renewed momentum.

Nice work Ayles, really cool.

But my question is who scalled on of these up and built a full size boat?

herr_oberst 10-26-2021 05:07 AM

It's too bad that the spars and ribs are always hidden on wooden boats and airplanes.

drcoastline 10-26-2021 06:15 AM

Ain't that the truth?

Got a load of parts this week and started assembling the drive train. Basically a thick tightly wound spring inside of a brass tube with a prop shaft on the flexdrive. Interesting stuff that I had never seen in person before.

Ayles, I'm going to be pissed if you don't put a scale model of Alissa White-Gluz at the controls of that bisch! :D

Id give her a ride in my hydroplane any time!!

Been a bit since Ive done anything so headed down to my workshop last night and started cutting! Been avoiding this because its scary to cut into the hull, but seems to have turned out all right. The pic shows the strut installed through the hull. This holds the driveline/stuffing tube and prop. There are a ton of measurements and theory on how it should be placed. I spoke with a few local guys and took their advice. 5/8” in from the transom and a 1/4” left of center.

The hard part now is installing the motor so it lines up with the strut…

Well Jeff, you've inspired me. Well, both you and Rusty Heap. I've been busy - all of my running hardware is now installed, short of the speed control, which is on its way from Horizon Hobby. Motor, strut, stuffing box, rudder, skid fin, steering servo - all mounted up. It will be in the water this spring.

I have to say, though, I'm a bit worried. You see, I'm using the Pro Boat UL-19 running gear all the way around. I gave up on making it "competition legal", understanding that my 1960's Dumas Miss Unlimited hull is vastly outdated. Too heavy, poor design by today's standards, all of that. So, being just a "fun boat", I went with the convenience of a proven package. I figure if it all works in unison on the UL-19, it should work well on mine.

Then I started watching You Tube videos of that UL-19. Holy crap - one guy gets it up over 90 mph with a custom prop, but all stock electronics and propulsion. Granted, he's running 6S battery packs, but still - my poor old lite ply Miss Unlimited would literally come unglued at those speeds. So, I guess maybe 3S packs for me, at least to start. More of a "scale" speed. Good thing I've got plenty of them for my R/C airplane flying.

Thats awesome Jeff, post a couole pics! Would love to see it since the last few photos you shared.

Ayles 12-18-2021 06:12 PM

Had some more parts show up and was able to do a bit of work on the framing that mates with the fiberglass cowling.

Finally started a little work on the rear wings. These come as rough fiberglass parts that need a bit of sanding to get everything lined up. I epoxied them together with G-Flex + west systems 405 filler and a chunk of closed cell foam for flotation. They are still going to take a bit more sanding and a little filler to get the edges and seems perfect.

I have enough epoxy and filler to work on a real boat at this point...

what's going to be the color scheme of your hydro? Miss Bardall yellow/black checkerboard
was always a fav of mine.

Ayles 01-28-2022 09:14 AM

I'm not sure yet, I might do something like Rainier Beer. But that never actually existed so is problematic for scale racing.

If you really do want to race it gets complicated with which hull you have and the paint scheme to go along with it. At that, most of the popular/famous hulls and paint schemes are already in use or claimed by club members.

Funny thing about Bardahl, If my neighbor cut down his trees I could probably see the factory's giant neon sign. Just a mile or two away as the crow flies.

Yeah, it looks like the only game in town around here if one wants to race is Classic Thunder, the only local club that seems to have a race schedule. And, yes, their "hull registry" shows most of the desirable boats have already been taken. The good thing is, though, their rules do not allow them to camp on a boat without actually racing it. It sounds like they are pretty strict about it - don't race it with them for a year (it might be two), and you forfeit that boat, and it gets put back in the pool for someone else to use.

They have weird motor rules in the lower classes as well. The motor they spec is no longer available, and has not been manufactured for over ten years. I've asked them about that. It appears there are enough out there that they don't think it's a problem. Besides, they all have theirs... not very welcoming for anyone interested in joining... Their modern era class is "any motor" and speed control, so the sky's the limit there. Not sure that's where you want to start, though.

So, I finally got the speed control and other items necessary to finish my boat. In short, I bought the wrong boat. My Dumas Miss Unlimited hails from the 1960's. I built one as a kid and ran it on a tether in the Sammamish Slough, at Marymoor Park, powering it with a Fox .35 control line engine. Just free running on a tether, like a control line airplane. Well, with the motor and speed control in hand, but with no batteries just yet, it's obvious this thing is going to be crammed full (if everything will even fit) and a good deal heavier than it was ever meant to be. I'm getting kinda discouraged...

I might finish this one up as a "display model" and buy a more modern kit. Maybe ML Boatworks, but I really like the idea of a fiberglass or carbon fiber hull. We'll see.

Jeff, I'd also reach out to Bill Brandt at Rattlesnake RC (Tri Cities). He will hop on the phone and get you sorted.

You can start a chat with him here (lower left corner of the screen) and then take it to the phone: https://www.allrc1.com/

Lots more wing work. The seam around the edge was pretty rough so I mixed up some more epoxy with some filler and ran it around the edge. Sanded it down this morning and its looking like they might be done!

Also worked on the mounts. They are made out of a scrap of carbon fiber I bought on ebay. Put a little radius on the corners to make them look a little better and drilled some holes to help with the epoxy.

That CF in the last pic is a trick little piece.

Ayles 01-31-2022 08:28 AM

Thanks!

Cutting it/shaping was far easier than I thought it would be. Used a small air powered cutoff wheel then a dremel tool with a sanding barrel to get the curve.

The exciting part is that once I epoxy in those carbon fiber mounts I can skin the left and right sponsons which is a huge jump forward.
