It is 44" long and, after trawling the internet for pilot boat photos, looks to be an old Halmatic Nelson 40 . That would make it 1/11th scale. Strange they didn't make it 1/12th scale.

sounds real nice size for a pilot boat.
i did see a 6 footer at beale park once, now that looked like you could almost get inside it


44 inch is nice sensible size

Now that is realy nice.
its not the same as the one i remember, the one im talking about the wheelhouse was not as long, giving more room behind it. but this looks to be a great model..
what is the beam of this ? 
with that top off you have a ton of room to play around under there.
will make a fantastic boat when finished.


i do like that, looks to be well made.

It does indeed. I like the old black & white scheme pilot boats used to have. The fact that the hull has a black gel coat and the rest white gel coat is an added bonus if she gets any scratches.

Coo, a scale Jetfoil!  %%


But how does it work in model form? The real thing had a very complex wave sensing radar in the bow that trimmed the bow foil to enable the boat to ride the wave profile. Plus lateral accelerometers to drive the stern foils to enable it to lean into the turns. So how do you do all that in miniature?


I rode the P&O Jetfoil from Tower Pier in London to Ostend once, and it was MOST impressive.

Cor Blimey - that would be a technically advanced Jetfoil model if it had all that spec working on it  O0

Beat me to it, has a few of them now I think. He posted up. A new one a day or three ago.  Have been watching him for a while.

Looks like he built a Jetfoil and a Pegasus too, with a gyro doing some of the control work, but those posts are ten years old and there has to be better methods nowadays.

...He might use a gyro but did he not post up hs latest model just under 3 weeks ago?  I was under the impression unless it's a surface peircing type like the greek gentleman posts on there, it's difficult to have a passive foil system.

i picked that one specifically because it shows of a boeing jetfoil...  but as RST says, that guy has several hydrofoils, all of which follow the same setup, and  others on RCGroups have successfully copied his technique

The gyro became more trouble than they are worth, but I think two of Takahashi san's hydrofoil still use them.
On some of his latest, it is purely a mix on ailerons and rudder, with a little bit of elevator to
prevent the nose from diving as speed drops in a turn. So the models are literally flown.

I like that pic, that's the USN Tucumcari, one of the earliest hydrofoils.  :-))

Info here -
https://www.foils.org/wp-content/uploads/2017/09/Radio-Controlled-RC-Model-Hydrofoils-Power-Sail-1.pdf
Some of those posts were back in the day...  :-)
 We were experimenting and there were only nitro motors, and small brushed test beds.
My first pump was essentially a blender, no thrust. The second used a racing prop, syringes and a used nozzle.
And it was years till I realized, I was choking the jet pump because the intakes were built to scale, and
too small to provide a good intake volume, choking the performance.

I still have a Hydrafibre 1/64 Type 21 Frigate. Quite a big beast.

The Rudder/ailerons are mixed, so when the model turns, it leans in, but applying the
elevator and managing speed are still up to the operator. Takahashi-san has had a keen
interest in the old HydraFibre kit, but has been unable to find one available.
