RC Boat 3DBenchy

Everysince i saw and printed my first 3Dbenchy i knew i wanted a RC-controlled one. After i printed one i realized that it doesnt float, so i decided to make one that floats and can be controlled by RC-controller.
I hope you enjoy this small project of mine.

How i 3D-model the benchy-boat:

I printed the parts with ABS 25% infill, the good part with ABS is that you can smooth it and make it watertight with Acetone,you can also glue the parts together with ABS-juice (Acetone and ABS mixed in a jar). The bad part is that you might experience some warping and cracking, i printed mine in an enclosed chamber but still had some problems with cracks. So it may be easier to just print it with PLA and watertight it with a coating and glue the parts with epoxy instead.

As i told you i used ABS-juice to glue them together, and some tape till it was fixed. I also used ABS-juice all over the body to make it watertight, 2-3 coats.

DO NOT use a gluegun, thats what i did, it do not work it doesnt get watertight, you sholud use epoxyglue and the screws for the jet motor and the rudder

Wrap a silliconetube around the motor and glue it to the motor and the hull to make sure the motor gets cool enought,

Glue the "pupil" to the boat and solder the leds to a 330 ohm resistor or one that fits your LED voltage, google it if you are unsure. Anode to + and catode to -

Mount the servo to the servo-support and insert the rudder-sleeve in the hole near the rudder. I have integrated the Servo-support now in the hull so you don´t have to print it separately .

Wire it as the diagram shows.

I had to solder a converting cable for my battery as it doesnt fit the ESC directly

Insert the steel shaft for servo throug the ruddersleeve and tight it to the rudder with an allen key.

Glue the cabin to the hull.

I fixed the ESC in the cabin and the transmitter in the roof of the cabin. I glued the antennas in the pipe. If you have the same RC-controller as me you can use channel 1 and 3 and you should be good to go. Just connect the battery and Enjoy :) you might have to put some weights in the back of the hull to make it work great. But its a really awesome boat.

You have your own Benchy RC if you have reached this step. I hope you had as much fun as i had making and playing with this awesome RC-boat.

If you haven´t built one you can just enjoy some sweet RC-driving on my youtube instead:
