Hitec HS-815BB Servo 3D model

Tonight I modeled the Hitec HS-815BB Sail Control Servo for use in both the Rip Tide and the Sun Wind II RC sailboats.

I'm going with a sail arm servo instead of a drum winch like I used on my Star 45 and Salish 475. I really want the deck to look clean, without any sort of shock cording like I have on the drum winch boats. Yes, I can use an internal self-tensioner, but a swing arm is also much easier to use.

It may not be as competitive, but on the other hand, a lot of guys swear by them and say that they are just as fast as the drums. Since I'm not into racing, I don't care and will go for simplicity. Besides, this servo is $50 compared to $300 for the RMG SmartWinch. RMG winches, by the way, are amazing! I suggest you use them on certain boats. But for the VM Rip Tide and Sun Wind II, I'm going with simple and clean.

Here's how the 3D servo looks. I wanted to make sure that it would fit, and that the arm had plenty of room to swing. Looks good so far!



Tomorrow I'll start on the regular sized servo (Hitec HS322HD) for the rudder, and then work on placing them on the board. I'll also have to work on how best to support the two different-sized servos, plus find places for the battery, receiver, and wires. Hmm... big challenge! But, the gentleman who makes the most amazing pond boats, has a picture posted that will give me some guidance.


Aloha!

Riptide RC Sailboat

Well I just hit the R/C Sailboat jackpot! Rod Carr, of Carr Sails in Redmond, WA, and the second ever member of the AMYA, just gifted me a Marblehead "Riptide" hull and many of the parts and templates to finish it! Thank you Rod!

I'm not sure when I'll be able to work on this, but hopefully it will turn into a fantastic vintage Marblehead. The gentleman who started it did a fantastic job. He was a true artist and I will do my best to get as close as I can to his workmanship but it will be a challenge.

Here are some pictures...


He even cast his own bulb and the mold came with the hull! I could probably start making my own fleet of Riptides as he also gave me many of the templates and such. I will only need to pin and epoxy the bulb to the fin and fair it smooth. It will be easy to do.


The frames look and feel like he hand cut them on a scroll saw, but they are very close to perfect. He used thicker plywood than I may have but they are very sturdy. The bow is very squ…

R/C Sailboat Builds

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!

Sun Wind RC Sailboat 3D Model

One of my current projects is to 3D model Gus Lassel's 1949 "Sun Wind" Vintage Marblehead (VM) sailboat. Apparently it was originally called the "Sun Daze", as in fun sailing on Sundays, according to Adrian Olson whose father had a connection to the original designer. (By the way, check out Adrian's other model yachts too. He does beautiful work!)

Boats back then were free-sailing or vane-sailing. I think this was a free-sailing boat but am not sure. My version will be modified for RC. All I have to go by is an old set of lines, but hopefully I can get a decent model out of it. Eventually I would like to make laser-cut frames from my 3D model and actually recreate the boat in RC.

Adrian Olson offers a modern fiberglass kit for the Sun Wind. The pictures look beautiful! My intention is to create frames so that a builder can make their own wood & fiberglass version. I really doubt that many people will want to go through the effort it can take to make a …

Vintage Marblehead Riptide electronic files

UPDATE: As of 12/8/2017, I was sent a much better TIFF file of the original plans by Ted Houk. See my updated post

When Rod Carr gifted to me an unfinished wooden Riptide hull, it came with a CD of files from the gentleman (a man named Roger, I believe) who made it. I finally got a chance to look at the files and what a great discovery!

Roger created not only several very helpful PDF files, but .dxf files too. With some work I could make files for laser cut frames, fin and rudder!



NOTE: I am not the creator of these files and cannot vouch for the accuracy of them. The creator of the electronic files is unknown but the original plans for the Riptide go back to 1949 and are most likely in the public domain. One version of the Riptide lines is being freely distributed. These files are the only ones I've seen other than the original 1949 hand-drawn lines. I put them here under an assumed Creative Commons license for NON-commercial work. You are free to make your own Riptide but only…
