Default Waterproofing Electrics

Hi All

Looking to build up a wet car for the coming outdoor season and just wondering what peoples opinions are on how to do this. After doing a bit of research i have narrowed it down to two options;

1. Pastidip for receiver and esc (then some silicone or bluetak around the sensor board on the motor)

2. A receiver box (and same option as above for the motor)

I will be running a futaba servo and understand this is reasonably well protected anyway, so will probably do nothing on this.

At the moment i am leaning towards the Palstidip option, as i feel more confident i will be able to do this well (worried about water getting into a receiver box.

Has anyone any experience of using the plastidip, does this really work or should i just go with the receiver box idea.

Any thoughts/comments/suggestions greatly appreciated

I always used to use baloons and then zip tie the end of it. Though depending on your esc plastidip may be a better option (allowing a heatsink to breath if esc temps are a problem).

Mark,
Plastidip all the way !

One thing I would suggest is taking the sensor board out of the motor and doing that as well before re-fitting. Don't forget to do the sensor cable housing as well, otherwise you might find you get some water running down into the sensor port on either the speedo or the motor itself. If your motor has cooling holes, a little electrical tape over those holes can help too, but it's not going to stop everything.

After your run, GENTLY spin the wheels up to flush out any sitting water in the bearings etc. Do not go to full throttle, we saw a lot of wet tyres explode like this last year !

I've found the connectors at the receiver to be a weak spot, with a sealed transmitter board (similar to plastidip). I used a factory waterproofed ESC from MRT back then. Current receivers and escs might feature buttons that may make things a bit harder to coard properly.
