Waterproofing a brushless a motor
 

I'm going to be running my b4 outdoors over the winter.

Does anyone have any suggestions on waterproofing brushless motors?

Many thanks :)

Get some rclazy goo over the sensor lead and connections, great stuff!

lazy goo waterproof
 

+1 lazy goo :thumbsup: that stuff is brilliant! warning....it smells like a cyanide factory on fire in an oil field thats next to a military grade glue factory:p!! so crack the windows when you do the job...amazing stuff

Cheers guys, I'll give the goo a try :)

Or you could try plastidip.
Its what a lot of the touring cars guys are building there wet cars with now.

You get a small paint tin pot sized and just grab whatever you want to seal and submerge it in the stuff.
When it dries it shrinks and grips to the item. Its also great to remove with no damage to the item and zero mess left.

i just stuck a big lump of blue-tack all over them

Don't forget about condensation
 

To do the job properly you need to take the motor apart to get to the sensor board PCB. This needs to be lazy goo'd or plastidip'd, myself I use plastidip

Something that is cold and wet, then gets really hot will produce condensation both externally and internally. This is why you see cars run for 5 minutes in the first heat then stop working. Then the same gear is fine a week later after its dried out.

If you want to see more about this have a look at the round 2, Cotswolds video on http://www.rcracing.tv/ its at the bottom of the page.

I've got some rc lazy goo on order :thumbsup:

is it safe to use directly on pcb's?

Yes it is Arran. I have opened up my speedo and receiver and put the lazy goo all over the circuit boards and everything is ok.

Might see you with some off roading this year mate during the winter :thumbsup:

Cheers Jordan, will give my electrics a once over with the goo when it arrives :thumbsup:

What car you running off road ? :)

I'm running a B4 as well first time doing off road so is going to be interesting lol

Do you guys use "normal" plasti dip or the "liquid tape" version?

Normal
