R/C ship with two propellers

I designed this because the other ship models I found are more complicated or need special mechanical parts. This one does not need a rudder as it is controlled by changing only the speed of the propellers.
It is not so easy to go straight, as seen in this video: https://youtu.be/IxbOy4HJPTo

You need these parts:
- M3 screws and nuts
- Glue
- 2 motors with 2mm mounting holes 12mm apart. I used DYS 1306. If needed I can design different motor mounts.
- 2 5" propellers

Printing:
It is important that the hull is water proof. On my printer I used PLA and bumped up flow to 140% and temperature to 210°C.

Updates:
- 2017-10-31: Modified Ship_Deck_Rear.stl so that the propellers point straight forward.
