RC Sailboat Servo Hookup and Tray (Board? Mount?)

The electronics for my upcoming RC sailboat build have all arrived, and I've also finished 3D modeling the electronics & servo tray/board/thingy that everything is mounted upon. My servo tray is designed to contain the two servos, and the other electronics, on a removable tray/board/thing. What exactly is it called, anyway?!

The hookups for RC sailboat servos and electronics are about as simple as anything can get in the RC world.

Everything plugs into the RC receiver. I'm using the Spektrum AR400 4-channel aircraft receiver.

The sail arm servo is plugged into the throttle receptacle on the receiver. I'm using the Hitec HS815BB Sail Arm servo. It's huge, and not particularly fast, but it should be plenty strong enough. I'm not racing so I don't care about the speed of it.

The rudder servo is plugged into the aileron receptacle on receiver, and NOT the "rudder" receptacle. I'm using a Hitec HS-322HD.

Plug your battery switch into either the "rudder" or "elevator" receptacle, not the "Bind/Data" receptacle. You can actually use any unused receptacle except "Bind". I'm using the Hitec Heavy Duty High Channel Switch Harness (HRC#54407S).

Plug the battery case into the switch. The servos I'm using are only rated up to 6 volts, so I'm just going with a battery case that holds four AA batteries. If you use servos that have higher voltage needs, then you might go with a Lipo battery instead.

And that's it! Of course, you'll have to bind your receiver to your transmitter too. See picture of the servo hookups below:

Here are some updates on how the 3D modeling looks. Here is the servo & electronics board. You can see that I've built a box to contain the servos and the battery case. Most of the wires will be routed through the box too, except for the battery case wire so that you don't have to remove the entire board to change the batteries. You should just be able to pull out the case.

Next is the board inside the frames. You can see the hatch cutout too. The board should easily slip out when needed... fingers crossed!

Finally, I added two half-circles to illustrate the sail arm sweep. By doing this you can easily see if anything is in the way of the arm, and that the arm can sweep through its entire range inside the frames.

That's it for now!

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?!

IOM Rig Box (IOM Sail Box) plans

So all the cool IOM kids seem to have nice wooden boxes to store their rigs in. This might be my next quick project then, so that I can pretend to be cool too. :-P

The rig box images that I've seen online are mostly similar, and would work well, but David Jensen from Bellevue, WA, USA (The same guy who designed a fantastic IOM boat stand I posted about earlier) has a really nice design that he shared on RC Groups. Or if that link doesn't work, the go here and search for "IOM sail box" or "IOM rig box".

It holds three sets of rigs for the A, B, and C rigs.


He also has a nifty way to attach his IOM boat stand, with a boat on it, to the rig box. His rig box has wheels attached, so once everything is loaded up he just wheels it to the launch spot. Very nice!



There are other sources online. They show different variations of the same type of sail box.

Here's a nice looking one.

Here's a YouTube video of a really nice one.

Will post more if I actually end…

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 …
