I remember years ago using my Lunchbox with a mechanical speedo and the receiver wrapped in a bag. I used to drive through deep puddles without any problems. A couple of weeks ago I drove my runner Lunchbox through one little puddle and five minutes later it stopped working. Water got in the ESC. (It did work again the next day once it dried out)
That made me think of a way of waterproofing the electrics using a small lunchbox (Pun intended lol) and mini fans for air flow to keep the ESC cool.
Up date 19/07/11 it works perfectly!

Just fits under the bodyshell Twin fans. One sucks air in-the other blows it out Platforms for elecs and divider for air flow Wires run out through rubber grommet Quick access lid with seal.

Great idea! Well done as well, but doesn't it defeat the purpose of the box by having the 2 fan holes in the bottom? Why didn't you mount them up higher on the side, or even the lid? Would mean you could drive through DEEPER puddles. LOL!

Neat idea mate. But after seeing videos of your driving it spends most of its time on the back wheels, so it avoids getting the chassis to deep in puddles...lol

Skottoman- I did think about putting the fans at the back but decided to put them underneath as I want to blast through puddles rather than go deep in water. Having them on the sides may allow water to spray onto them easier. The other thing is if they went on the sides they would have to be low to allow room for the lids clips. The pictures don't show it but I have sealed the sides between the box and chassis- the main place the water will hit. Also, the box has a lip all around the base which should allow water to drip off before it gets to the fans. (lol, I hope)

djp780- lol good point mate! Maybe if the box fills with water it'll help keep the front down for a change lol! The 17double motor does keep the front up for most of the time, but at least the standard Tamiya ESC has held up well- I know the limit is 21turn (?) but it seems fine.
