Com-pac R/C modeling

[Salty19]

I'm toying around with making a scale model of a Com-pac (model undecided, but I'm considering mirroring my own boat) with radio controls to essentially turn it into an R/C controlled boat.  I would put a small diesel in it or perhaps a nitro powered motor (I have a 1.6hp nitro on hand already)

Has anyone done this?

This project won't get started anytime soon, really just looking for ideas and discussion around it.  Yep, I know about the R/'C forums and have done a little poking around but there is much more to learn and this group may have actually done one before.

This would be my first modeling experience building from scratch. I expect it would take me a year to build, chiseling away at it little by little in spare time (say a 2 or 3 hours a week).

My questions to you all are:

-Has anyone done this?
-Should this be made of wood or fiberglass? I'm leaning towards wood as I have zero experience with fiberglassing.
-Are there any molds available to use, should fiberglass be the best means?
-What scale ratio do you think would work well?  I'm thinking 7:1 but not sure.
-What kind of cost would I be looking at with a small diesel, assuming procuring the components at good rates and using some materials from around the house.
-Is anyone else interested in this that we can share ideas offline?

I used to have a Kyosho Fairwind RC sailboat.
IMHO, forget the nitro or diesel. If you just want insurace to get the boat back to shore if the wind dies, put an electric motor in it.
Most RC sailboats I've seen are setup 2 channel, 1 on the rudder and one on the main. You'll want to use one of the sailwinch servos on the main.
Dumas has a few sailboat kits, maybe you could start with on those kits and modify it to scale your 19

Mike. Capital Idea!
I have the scale drawings of my 19 that I did years ago. The line drawings for the keel/hull and the deck drawings.

What I'd do is Xerox the drawing, cut out the shapes and glue them onto card stock. Cut the card stock and make a set of templates.
Start with a block of foam made from layers of 1" pink insulating foam board glued to a flat chunk of wood. Your going to build the boat upside down. And sand the foam board to shape using the templates to find the line of the hull.
Go to Hobby Lobby and buy some 1/2 ounce glass fiberglass cloth. A qt of Hobby-Poxy resign with hardener and lay that impregnated cloth over the foam. One layer of cloth, two coats of epoxy. Sand the epoxy till smooth, and when your happy with the feel of the shape, dissolve the foam out of the mold. Epoxy in some bass wood, lay up a deck and finish the rig. Paint the boat, sow up a head and main sail, install the R/C rudder, winch, servos, tray, and battery componets...go sailing. Model would be about 14 inch long, x 5 inch wide. Mast is 25 foot waterline to top-o-mast. In scale.

Skip--thanks for the input, much appreciated.    I'm in no hurry on this project at all..probably will wait until winter anyway.  Planning now for the work to be done later I guess.

I see you're into R/C as well and this has peaked your interest.  Are you considering making a scale C&J as well??

I sold my beloved CP-19 a few years ago.  Now I'm hoping to convince my better half that a CP-23 would be a really good thing to have.

Meanwhile, I'm  just starting to plan a project I've thought about for years.  That is, carving a halfhull model of the CP-19.  I've done a lot of woodcarving over the last few years - and have gotten pretty good at it - but this will be my first attempt with a halfhull.

Any line drawings (or perhaps lines drawings?) you might have would really be helpful!

Billy:

Neat CP-16 halfhull!  Hmmm - at 1/4" per foot, the hull of this model is only 4" long.

I'm considering a halfhull of just the hull and keel of a CP-19.  I'm making it to 3/4" per foot scale, which will give a hull LOA of 14-1/4".  I can get a pretty close approximation of shape just from my recollection, my photo archives, and a drawing that I downloaded from the internet - but a set of real lines drawings would make things a lot easier - and produce a more precise model.

It will be carved out of mahogany, and have a tung oil finish.  This will be mounted on a display board that's probably going to be oak.
