Realistically, how much water can an MMM handle?
 

Hey guys, the title is pretty self-explanitory. I am trying to figure out a way to keep the snow off the speedy in my savage flux. So far I have tried afro-engineering some tape around it which worked alright, but there was still some water on it. I want to keep it water-resistant but still be able to breath. Kind of contradicting if you ask me :lol:

So back to my original question though, how much water can the speedy take before it goes to smoke land?

I dont know how much actually amount but heres my experience..

NAy snow that gets close to it melts away. You should be fine

Can't you open the case and blob silicon over everything but the heatsink?
I don't get snow, so this is more out of curiosity for myself.

Hard to Say, I have seen some get soaked and last fine, and another fry from a couple of drops in the wrong place.

my mm has been soaked while bashing up north it costed me $50 bucks too lol but it can handle quite a bit keep a eye on it tho.. put it in a balloon??

You could encase the whole ESC (up to the heatsink and connectors) in epoxy. THat would definitely void the warranty, but no water troubles .... at least not on the ESC...

But then my worry is heat. If I were to coat it in anything, I'd wrap it up and plasti-dip it, however I think it would overheat due to no airflow and the fan wouldn't be able to even do it's job. I will see what I come up with and maybe post some pics. Here's to hoping I don't kill the speedy!


Edit:
Ahhh I just re-read your post. You mean coat everything except basically the fan? The fan looks like a perfect spot for water to get in to me....

I'm assuming thermal epoxy would be the best option? Then fit it to an ali casing while the epoxy is still going off.

I think he means take it out of the casing first and then coat it, then put it back in the casing.

I bashed with a MMM in my E-revo all last winter in the snow with no problems. Biggest recomendation is to cover all holes in the body ( any holes drilled for air flow) since if there's snow on yhe ground it should be pretty cold out and lots of airflow isn't needed. Other idea I have is a box just big enough for the esc and a lid that will go over it, put some spacers in so that the top doesn't seal it off. This will allow room for the wires to go out and some air to get in but snow should have a hard time getting in. If interested in more details I will make a drawing and take a picture to post up

Or a box with a big lip on the lid and "spacers". Hmm, good idea's guys!

my experience

Actually, coat everything up to the heatsink. As long as there is a seal between the heatsink and the coating, it's waterproof and there is no thermal penalty. Although, I personally would want to heatsink the BEC. It's switching but it does produce some heat.

shower cap, elastic and plastic worked well for my emaxx. good luck snow is my favorite surface

I am so surprised no one else caught the wording above.........

:lol: I caught it, haven't heard that one before.

I would try putting it in a tupperware container and checking often to make sure it doesn't overheat. If heat is an issue then drilling holes in the bottom should let enough air flow through it to keep from getting too hot.

Well, in my experience it's a nicer version of a derogatory term. Maybe others see it differently.

It happens to the best of us. no harm done:wink:

8 mins?? oh lawd.. i watched it tho.. wonder if works for my MM?.. i never knew you could submerge a brushless motor.. interesting..

Hmmm I may go to town with the plasti-dip on it and also figure a way to stuff a heat sensor off the dx3s in there to keep an eye on things? It should thermal first though...

:intello:

PARK IT FOR THE WINTER.:lol:

Plasti-dip is easier to find but, isn't a conformal epoxy coating the correct stuff to use?

No way in hell im gonna chance getting my $1000 Flux wet.

Live a little! The waterproofed esc worked dandy, however the lipo's didn't like the cold so much! Live and learn.

What happened to your lipos? I run in the cold all the time and have never had a battery problem. My fingers freezing up is the biggest problem :lol:

Would plastic sandwich baggies and zipties be sufficient for lipo protection? Once they reach their "operating" temperature they shouldn't mind being out in the cold.:oops:

I will also need this:

If you're worried about getting them wet, I'd use a balloon and zip tie the opening. I leave my lipos indoors around 70 degrees so they're fairly warm when I start the run and usually only 80-90 degrees at the shrinkwrap by the end.
