Hello,
I recently finished building my Tamiya M05 chassis, but I have one question:
How can I make it water resistant?
I'd like it to be able to go through puddles of about 1cm deep and go on wet surfaces without killing the electrics. Does anybody know a good way that is fairly simple? I was thinking of spraying WD40 on it.
Thanks,
arvt

will you use brushed or brushless motor?

brushless motor do not like water.

brushed do not care

plastidip is a great way to insulate electronics against water.

use the traxxas 2075 waterproof servo and waterproof receiver box. Plastidip for speedy & brushed motors dont mind water. Look up waterproofing electronics on youtube, heaps of vids there

I don't really know the difference between brushed and brushless and I don't really want to buy new electronics, so thanks for the Plastidip recommendation and I will look at the YouTube videos. Thanks

The biggest difference between brushed and brushless from an outside view is by looking at the can of the motor. Brushed motors usually have lots of venting holes on the can. I have 4 different brushed motors sitting in front of me, Epic 27t (stock motor) has 2 sets of 3 holes on the can, Epic 19t (super stock motor) has 2 sets of 2 holes on the can, a Kyosho XSpeed 11t (modified) it has a it's venting holes on the end of the can by the pinion shaft, and my Reedy Radon 17t (SC10 stock motor) has only 4 holes on the can by the pinion.

Every brushed motor I've seen has a sealed can design. That's how you can tell brushed and brushless apart. That and brushed cans are usually smooth while brushless are heatsink grooved.

Another way to tell, all brushed motors have 2 wires, all brushless motors have 3 wires.

2 vs 3 wires (+extra sensor wire in case of sensored motor) is the easiest way

Thanks to AudioStylz and wallot I now think my motor is brushless, meaning I'm screwed if it gets in water without Plastidip. I've seen the website and there are loads of products. Which one is best to protect my battery (if necessary), servo, receiver and motor?

put your electrics in a ballon and you should be fine.

arvt

Yeah but don't they get very hot? Couldn't the balloon melt, or even burn?

The depending on how your car is geared. My M-05Pro doesn't get all that hot outside of the motor. The esc gets to about 90* at most from all the corner exit acceleration, batteries if there LiPo do not get hot at all. Maybe room temp at most. If your using NiMH batteries they can get up to 140* but still shouldn't melt the latex/rubber combination of a balloon.

Forgot about the sensor wire plug. That's a huge difference between the two.

If you're running in water or snow the ambient temperatures (if it's winter) and the water splashing around everywhere will cool them off.

arvt

Thanks but I'd rather not have to put it on and take it off.

arvt

Thanks for the feedback. My M-05 (standard) I don't really know yet but it has the motor that came with it. However I heard the battery can get up to 100 degrees Celcius

Well you can plastidip everything but you'll still run into heat issues if it's hot out.

Best solution would be to buy Traxxas waterproof servos and the VXL ESC and motor, but if you don't want to buy new stuff, then I'm not sure what to do.
