SO i just bought a comm lathe and a diamond bit and lathe motor and a couple expensive brushed motors just so I can take my wraith in the water. Really wanted brushless but everyone said no. But now the Yeti has a waterproof brushless! WTF ! my brushed stuff has not even come in the mail yet and I already regret it! Someone make me feel better?

This may may you feel worse, but you can get brushless motors from Ebay that are waterproof for 20-25 dollars. Do they run hot? Yes. Are they the best money can buy? No. Are they better and cheaper than an old fashioned brushed motor? Absolutely.

I have completely submerged my Castle 3800 KV motor several times and it runs perfectly.

Why does this never come up when it is being directly asked?
O well I got a some super torquey HH motors now. Soon to be a pro comm cutter.

my Castle 3800kv has also gone for a swim in Lake Tahoe accidentally in my slash. Ran in to get it and kept tearing up the beach

Let me assure you that if you submerge a brushless motor of any type it will screw it up over time. Even the velineon motor gets it's bearing screwed up and that needs replacement (I hate that motor btw) but seriously you'll end up ruining this motor if you keep it up..these are meant for racing not freaking trailing or water runs! It's your motor go ahead and screw it up but I certainly would NOT run that in the water anymore!

Thanks for the great review,looks like a well thought out and built truck.Was wondering if it will be available in kit form any time soon.

closed diffs are diffs with oil inside them. open diffs basically means both wheels can and will spin at different speeds to help with cornering. locked diffs mean both wheels spin at the same speed, no matter what. this is used in most crawlers to help with traction and grip. if you wanna know more details, Google's your best friend.

Thanks for this thread badger, lovin' it!

Both brushless and brushed motors have bearings. That damage to bearings affects both motor types.

I am not advocating that these motors should be used in a pool. I am saying that they can survive. I can service a motor with the best of them, so I am not too worried about anything going wrong.

Brushless motors will continue to improve and brushed motors will eventually go the way of the dodo bird and buggy whip.

I also hate the Velineon motor. It's expensive, and there are far better options available.

ah thanks !

funny thing though, a diff, is a gear box, so wouldn't all gearboxes have to be closed ? or encased in plastic or metal ? otherwise the gears would be showing and die in minutes if running through dirt and sand.

You need to watch this video. This shows how a differntial (meaning an open differntial) works. A closed, or "locked" differential just means both tires always spin together.

It's okay to look back in the thread to see if someone has already answered your question.
