Step 2: Start building!

This was my third attempt at making this boat. The first didn't work because all the circuitry was exposed and water splashed onto it. The second one was more elevated but only balanced on two 20 ounce coke bottles. It flipped in the bathtub. Whatever you do, make sure that your boat's "brain" is hidden from the water. I put all the circuitry into an old butter container. If my boat flips, water will probably leak in, but at least it's splash proof. The butter top is part of the boats hull, all the electric stuff is glued into the tub part, that way it can be easily removed.

The first thing i did was stick the main chip inside the butter tub. I then made a hole for the wires that lead to the engine and another for the antenna. I waterproofed them with a glue gun (I actually did all the pasting and waterproofing with my glue gun.)

I then punched a hole through the back with one of the steel push rods. The push rod is attached to the servo and will control the rudder. This is the only hole I didn't waterproof since the push rod needs to move back and forth through it. It's small enough to not be a problem though.

Next, I built a tail and rudder from some unused ziploc Tupperware. The hinge was a problem though. It needed to be strong enough to handle the push and pull of the push rod, but pliable, since the servo isn't that strong. I ended up using the hinge of a Tic-Tac box top. The hinge is a live hinge, because it has no moving parts, just a flexible polypropylene membrane. I aligned the hinge with the push rod since it would be absorbing the push rod's force. The top hinge is just some scotch tape. I pasted a little tab onto the rudder side of the hinge and attached the push rod to it. When the servo pulls, the rudder turns to starboard, when pushed, the rudder turns to port.

Next, I cut out the flat side of the tic tac box (to minimize air resistance) and used it as an engine mount. I hot glued the engine to the top. When used, the engine gets hot, but not hot enough to melt the glue or weaken it significantly. The engine and controls of the boat are now complete.
<p>is the motor waterproofed? </p>
Very nice and informative post thanks for sharing and realy flawless home made <br><a href="http://www.nitrotek.nl/rc-boten.html" rel="nofollow">rc boat</a>
Mind blowing job man how did you made this.? Now i'll must try to made this kind of <a href="http://www.nitrotek.fr/bateaux-rc.html" rel="nofollow">RC boat</a> with my old scrap rc toys thanks for sharing this nice infromation.
Thanks for taking time for sharing this article, <br> it was excellent and very informative, This building of <br><a href="http://www.nitrotek.nl/rc-boten.html" rel="nofollow">rc boat</a> is very enjoyable. <br>It is fairly easy to locate materials and plans on the internet,
Why not take what you have and make another airplane? Check out the free PDF plans at http://www.rcpowers.com/ <br>Just watch some of their videos. wow!
if you wanted a tri-maran, you could put the elecronics bottle in the water, have the rudder rod at the top, so its out of the water-no leaks!-and use like a kinder-egg tub thing with fishing weights or something to stop it flipping.... <br> <br>illl draw something up, it might help explain it.
good old MS paint
also, would you be able to mount like a pen-can inside the electronics thing, and you could get underwater footage
&nbsp;hey.....how is tht push rod makin a turn ....how did u make the contact link between...the tic tac hinge n the tail fin....please ...can u give a brief abt tht....
do you live in Bristol-uk? kuz i think i know u...im richard? recognise the name?
i had the same plane but it flew from 200 feet straight down into the pavement. it was completely smashed and the servos snapped off the pc board but the motor, battary, and motor control were still god
there were god? <br>wow...
Ouch. Should be salvageable.
wasnt... the pc board looked like it went through a blender. if i still had it i would post pictures
Yep. Ouch.
This illegal. Boats and planes have a different frequency.
get different crystals?
&nbsp;please tell me.
&nbsp;how doeas the rudder move?<br /> <br /> please post a video<br />
&nbsp;actually i dint understand what ur servos are doing!<br /> <br />
wat is the best amount of blades on the fan<br />
HA... lol I was just thinking if I could make an RC PLANE out of an old RC BOAT :D
i have a hobbyzone plane almost like that. I have the Firebird Outlaw- it has 2 engines. mine unfortunately got run over by a car (i got a second one haha). I was in an empty parking lot doing a rolling takeoff when a car decided to do a uturn thing thru the lot and happened to be out of my vision as i was about to take off and hit the fiberglass tail, sortof luckily. i was thinking about what i could do with the leftover electronics, thanks for the inspiration! :) btw great instructable,
you should make it into a hovercraft
Copycat! just kidding. i will/am doing this to one of my crappy planes that doesn't fly well and souping it up with bigger motors, more control, and a bigger plane. I took the servo, circuit board, motors and antenna out of my old plane. I put the motors in the middle of the wings, and set the tail rudder/elevator at zero. i'm also going to make it so it has landing gear and is able to take off/land in water! i'm a nerd, i know, but its what i do!!! P.S. For all you who think being a nerd is a bad thing, let me remind you who the multimillionaires/billionaires are. ;D
Initial design with butter tub looks like the Proteus Catamaran, neat design.
Why dont you just throw the plane in the water with the other parts covered with tape? It should work.
Stability. Also, then you would have a submarine, without a way to get up. Do we know what it looked like when crashed?
duh that was a dumb one
Then say so. I like answering dumb questions.
who doesn't
Wow, that's awesome! Looks great, easy to make, smart idea! I can tell you are going to be making great things for the rest of your life.
I second that. Great idea. I like the bit about 'make your boat unique'. That was a good idea.
Cool! I did this (sort of) a while ago with my cousin, using styrofoam and a motor from a PC. Those motors are brushless, so we decided that it'd be alright to submerge them in water. It actually worked for quite a while... until it was stepped on.... Nice job, though!
So brushless motors can work under water? I.e. brushless CPU fans etc? Don't they corrode or short circuit?
Yep, one of those brushless PC fans. I'd assume that they will corrode after a while, but it seemed to work for quite a long time. Nope, they don't short underwater.
really, I have to try that. I have like 10 laying around.
the circuit will corrode but corrode but the motor in pc fans are pretty well sealed. I actually have been working on plans for a submersible using pc fans.
I tried to make a boat. Styrofoam bowl, motor and battery. It was terrible. The battery got wet and the motor was not very powerful. A stronger motor I had got messed up by cheap solder, it didn't stick so the plastic melted from my soldering iron. You last boat design looked a little strange, but cool. After read this instructable, I will try to make something better. Nice instructable!
does any body know how to make a simple circuit that, if I push a button on a remote an led or something else turns on that is a couple of meters away (wireless)
if you hook up a radio receiver to a amplifier you will get a current that you can use to power other things. I imagine you could cannibalize parts from a set of walky-talkies and a cheap kids megaphone to do this. just hook up the speaker in one of the walky-talkies to the microphone wires in the megaphone and the speaker in the mega phone to the object you want to power. I've never done this but it may work if the mic wire doesn't burn out.
Yea, I done that! Works grate! Thanks!
1:can I ask what your using it for? 2:if you make an instructable could you credit me for at least part?
1: Just messing around, making LED light up by a push of a button on a remote. Im just having fun... 2: I am not making an Instructables about this...
why not?
Why should I? I need materials, but I dont have money to spend right now
logical reason not to (money) but if it works and others could use it is it not in the spirit of the site to share?
