watterproof BL esc for a maxx on 4s???
 

I was thinking of makeing my maxx into a winter basher, I reallly want to keep it BL....

it needs to run a tekin 2250 truggy motor on a 4s lipo
needs to be watter proof
needs proportional brakes
doesn't need reverse
needs to be <$150

any sugestions??:neutral:

You can take a MMM and encase it in epoxy...

and when it fails....

buy a new one.


You could get a nice tupperware and mount one in there. Seal up holes for the wires to exit.

MMM has a coating on the electronics that should keep it "water resistant". Just blow er, spray er with WD40, the blow her again and she should be good.

Yes, but I wouldn't suggest submerging it in water this way...

Or add some corrosion x to the board, pack the case with dielectric grease and say a prayer before you go out.

I was wondering if taking one of those flexible freezable cold wraps and putting it around the motor would do any good? Kinda off topic, but that could be handy for someone doing a shorter run or race. Takes a while for my head to get the wrap warm, not sure on a motor though...

If you can find one, the old Mtroniks truck ESC speed controls were completely waterproof. Not sure how it would run that motor though, but a 7XL smoked mine and they are supposed to be good for an L motor. They were only rated 80A, but with the motor that came with the setup, it was enough to move an emaxx pretty descent.

Get MGM .. I've had luck with mine in the winter months... i

I saw one of those a few months ago, the guy wanted somthing like $80 for it though...

They are good controllers, just a bit outdated. Only downfall is 5V on the servos instead of the new controllers that are higher. They are also a bit funny and you have to watch out as when you turn them on they look to calibrate the radio every time. I've had a couple of issues not paying attention pressing slightly on the trigger during calibration and then having the vehicle go WOT on me.
I think they pared them up with an 8L motor from the factory. Still cant figure out why a 7XL would smoke it so I would be a bit worried running it on a large motor.

Something to do with the fact a 7xl can pull 100amps easy...

Why are you dead set on a T8 2250 motor?

What about the Mamba Maxx w/ a bec? I run it with a the Neu 1515 1y on 4s all year around in my G3R. Unless there is something about the motor you are wanting to run that doesn't work on the MM controller.

yes, I'm not buying another motor...

Those L motors can pull some serious amps when they are not geared properly. I figured an XL would pull the same or better as an L if it was geared for the same mph. I had the 7XL with 20/68 gearing on my emaxx which is what everyone was running the MM with on 4S. So ya the controller is not going to be as beefy as an MM and may not run the bigger motors, but waterproof it is.

The MMM isn't nearly as water resistant as the MM, I lost two MMM's last winter from a tiny little bit of snow getting in the esc... I was only running on the road, not baja'n the deep snow, when all of a suddin, magic smoke! Then the very next day the same thing happened (with another new MMM), magic smoke...

Meanwhile I can practally submerge any of my MM's... Got one MM thats been running strong, year round since 2006!

We need REAL WATERPROOF 120-200A (CONT) BL ESC's and Rx's!!!!

/rant.

:diablo:

The easiest way to waterproof them is to encase them in thermal epoxy. They will still dissipate heat as well as provide water protection.
