C3PO Posted April 19, 2009 Share Posted April 19, 2009 What would I need to do to make my brushless motor waterproof for rain events? Quote Link to comment Share on other sites More sharing options...
hide Posted April 19, 2009 Share Posted April 19, 2009 AFAIK you can't waterproof brushless motors. Quote Link to comment Share on other sites More sharing options...
C3PO Posted April 19, 2009 Author Share Posted April 19, 2009 So they cannot be raced in the rain then? Quote Link to comment Share on other sites More sharing options...
joe of loath Posted April 20, 2009 Share Posted April 20, 2009 They can, but I would imagine only sensorless ones. The sensors in sensorless ones will probably pop, unless there is a way to seal the backplate with the sensor inside. Quote Link to comment Share on other sites More sharing options...
Garry Posted April 20, 2009 Share Posted April 20, 2009 Blu-tac around every plug, hole and connection, its the only way that is non-permenant. The other option is Shoe-Goo, epoxy or some type of sealant. But 99% of brushless ESC's aren't waterproof either. Quote Link to comment Share on other sites More sharing options...
mad-wolfie Posted April 20, 2009 Share Posted April 20, 2009 But 99% of brushless ESC's aren't waterproof either. Agreed.. those that say they are "waterproof" are merely splash-proof. which means a couple of drops of water coming off the tyres once in a while won't do any harm if it lands on the ESC , but if you drive through a puddle or park the car in deep melting snow & leave it switched on, then it will fry in an instant. the way they get round it of course is they don't say "100% waterproof" so chances are they will not be properly waterproof ESC's... that is what they will say at least if you try to argue the case.

I'm sure I saw a video of an ESC running a motor with the ESC completely submerged in a tank of water a few years ago... Quote Link to comment Share on other sites More sharing options...
Garry Posted April 22, 2009 Share Posted April 22, 2009 LRP proving the waterproofability of their Quantum 2 ESC: (FLV file, 5MB) http://www.lrp.cc/de/media/download/videos...action/?file=75 But from my experience, very few ESC's are truely waterproof (only MRT, and Mtroniks). And no sensored brushless ones at all. In wet racing, most people use wet boxes (a pot or component box that has all the electrics sealed in), but isn't cheap as it means needing a second set of ESC and motor thats sealed up with resin/shoe goo. My ESC isn't waterproof, so I'll sit out wet meetings. Quote Link to comment Share on other sites More sharing options...
Matt B Posted April 22, 2009 Share Posted April 22, 2009 I think the one that was shown as watrproof was the Mamba 25 (for 1:18th scale vehicles). Not sure about the Mamba Max though. Quote Link to comment Share on other sites More sharing options...

My ESC isn't waterproof, so I'll sit out wet meetings. true.. i've seen all sorts of waterproofing methods, including even tupperware like boxes that are intended to put dentures in being used to house the electrics & even condoms obtained from the machine in the nearest public toilet or people asking for directions to the nearest Woolworths (OK it was a while ago) or the Early Learning centre to get some plastercine! What i'm going to do though is keep a pre-soldered & programmed Mtroniks ESC & a brushed motor in my bits box.. then if it was to rain & i'm using brushless, do a quick switch... couple of screws, a couple of connectors & a sticky-pad (although Velcro may be an idea), then it's job done Quote Link to comment Share on other sites More sharing options...
