100% Waterproofing?

[BL_RV0]

So, I found a really good deal on a new E-maxx 3905. My friend has a pool, ramp, and a video camera. I have the money for this E-maxx. Here's the things I'd be worried about:
Antenna Wire: If water touches the bare tip of it, bad stuff might happen.
Possible solution: doubling over the antenna and re-stuffing it through the antenna tube, use an antenna cap and shrinkwrap it to the antenna tube.
Motors: I hear that titan motors don't like being completely submerged in water.
Possible solution: get a pair of different motors (which would be good?)
Most importantly, batteries. To keep this thing afloat, I will probably pick up a pair of 2s LiPos. How can I make these waterproof? Maybe make a cover out of lexan or something and put some rubber around it?
Connectors: I will use deans obviously. Are these waterproof enough as-is? (Assuming they are shrinkwrapped properly.) Or is there a way to waterproof these?
I will probably pick up a set of stainless steel screws also so the stock ones don't rust.

Antenna wire: Most antennas are more sensitive when being used to transmit, but sealing the bare wire is a good idea. Folding it over, putting a cap on it, and heatshrinking is a good idea.

Motors: No matter what, you're gonna get water in them. Don't know what would make Titans more sensitive than any other motor, except maybe the quality/composition of the brushes.

Batteries: Tough call on that. Best bet would be to encase them in a rubber balloon or something like that and seal the end. However, this would impede cooling, so watch temps. A lexan case could work too, but probably tougher to completely seal up.

Connectors: Don't worry about them. They're gonna get wet, and any waterproofing solution will make connecting/disconnecting them a PITA. Yeah, you may get corrosion on the non-gold plated parts after a while, but they are cheap to replace.

I take it the ESC is waterproof? BTW: there is a difference between water-proof and water-resistant. One means it's ok to submerge, the other means it's ok to splash water occasionally. If you seal up the ESC to be safe, watch cooling...

Motors: Don't people run motors underwater to break them in? (keep in mind this a brushed truck) I don't really see the problem with running them underwater some.
Batteries: Cooling will not matter as the batteries will be underwater, the balloon idea is great because it is removable, so I can take them off when I am not jumping my truck into the pool.

EDIT: The ESC is waterproof, IIRC.

I dunno. Who runs brushed motors?

[BL_RV0]

YOU!

[BrianG]

No way, the only brushed motors I have are the ones in my electric toothbrush/shaver/etc.

You'll be thrilled Brian - I believe the issue is because the motors have built-in fans. Running under water trying to push water with the fan is a bit too much for it.

Also - I've read on those "other sites" that the motor tend to corrode rather quickly if completely submerged.

[BrianG]

lol, see?! Fans are bad. Period.

What is a brushed motor? Is it stainless with a brushed finish? Is it hairy?

I need pics, as it sounds powerful. I may want to trade my neu for one.

Brushed is one step up from nitro. It's electric, so it's got that working for it at least, but that's it.
