This weekend I was able to get several small, but necessary, steps done on the full build of the Sun Wind II RC sailboat. The three double-frames are all laminated, and the remaining frames are clear-coated with epoxy. The fin was entirely laminated, shaped and fiberglassed. The rudder was laminated but still needs to be shaped. The aft rudder tube keel assembly was laminated. The three aft pieces are held in perfect alignment by two alignment holes that you stick 1/8" stock through and epoxy in place. I'll later sand them flush. The idea is that the keel piece that is just forward of this assembly will align to the forward three alignment holes and leave a 5/32" gap for the future rudder tube to go through. It's upside down on the table so that the flat top edges can be used to help keep it in alignment while it cures. Next, I still need to finish the aft keel glue-up, as well as gluing frame 0 to the forward keel piece. But then ...

Last night was spent avoiding the State of the Union address by instead working on the latest, and hopefully final, version of the Sun Wind II laser cut frames. Unless something obvious comes up, this is the file that I will shortly use to make the complete Sun Wind II boat from. It's nine sheets. I know that someone out there could have puzzled this together better to make it fewer sheets, but whatever... Six sheets are 1/8" plywood, and three are 1/16" plywood. There is a tenth sheet that can optionally be cut from 1/32" ply. The only part on it is a spacer for the rudder, but alternatively you could also just grind the edges off of the 1/8" rudder post to get it down to the 7/64" thickness of the actual rudder inner piece. Either way you run the risk of being slightly off-center with the post, but the amount should be so little as to be inconsequential. More later when the laser cutting starts... hopefully next week! Peace!

The planking was finished this morning, and by this afternoon I was able to sand it and add some 1.4 oz. fiberglass. This is a mock-up, half-built hull to check for fit and fairness. I purposely didn't fiberglass the entire half hull so that it could serve as a demonstration for my school. Should be fun to look at! Will trim the excess glass this evening, and then tomorrow will cut it off of the base and take it to school. Tomorrow I will attempt to turn some wood that I glued up on a lathe. Hoping to make a male mold for the lead bulb. Not sure how that will go as I'm crappy at turning. Fingers crossed! Peace! Thanks for visiting RC Model Yachts. This site focuses on the art of building radio control wooden sailboats. See the links to my other wood radio controlled sailboat pages for more resources, model yacht groups, rules, suppliers, and more.

At this point, I feel that I have now pretty much finalized the new Sun Wind II RC Sailboat lines. And I like it! Today I finished the servo tray (see previous post) and cleaned up a number of extraneous lines and such. I think she's done. The original 1949 lines : Profile view of my updated Sun Wind II lines : Note that my transom appears to be flat, not rounded like the original. When built however, this boat will also have a nicely rounded transom when a wood finishing piece is added. Likewise, the bow will match the original bow lines when you add the shaped bow piece. These lines are for the purpose of making laser cut frames. Front view of my updated Sun Wind II : Aft view : Would love to hear what people think! Aloha!

Hopefully this is my final rework of the Sun Wind II servo tray. I've repositioned the rudder servo, and sunk it into the board. There are fewer walls and pieces. It's more compact. The battery case will be held in place by Velcro and a small retaining wall. This should be sufficient and will allow for a tiny bit of battery repositioning to better distribute its weight. Almost done planking the test mockup half-hull. Will sand afterwards and then partially cover with fiberglass. Peace!

While waiting for epoxy to cure on my Sun Wind II mock-up hull, I've finally been working on making a 3D model of the 1949 Rip Tide. I started with some curves that were drawn in AutoCAD by a gentleman named Roger. For now, I'm simply calling it the Rip Tide II. After a false-start a few months ago, I now have a nice 3D model that is almost ready to create some laser cut frames. Here's an update... First, these are the lines that Roger made based on the original lines. I've seen the original lines that are going around the internet, and they are pretty crude. So Roger did a great job! Then, from Roger's 2D CAD drawing, I have made a 3D model so that I could test the fit of all the parts and frames. I've also made changes to the design to make the Rip Tide a "High Flyer" RC sailboat. So I dropped the draft to 16" and added a spade rudder. Here is what it now looks like... I also built a building base for the frames to help with a...

Here are the other boats I've built in the past few years: 1. A Tippecanoe T37 . These are kits available from Tippecanoe Boats in Washington State. 2. A classic, wooden, Star 45 . It has been officially measured and is class legal. The Star 45 is a pretty, classy, builders boat that has withstood the test of time.   3. A Salish 475 . It's my own variation on the Star 45. It was built from the same laser cut frames as the Star with a number of modifications aft of frame 6. It is an update of the classic look and was an attempt to mimic a modern ocean racing yacht. I've also built four Pygmy kayaks and many other projects. It's all fun... right?! Aloha! Radio controlled sailboats
