Traxxas E-Maxx 3905 bashing with EZrun 80A + 2350KV Combo

Just a quick vid I threw together of a few bashing sessions.

Truck was using stock gearing, 19 / 68, but with the 5mm bore pinion included in the EZrun combos.
Batteries are 2 GE Power 4000mah 2S, wired in series, so it's really 4S.

Runtime was about 20 minutes, and everything stays cool. The motor gets no warmer than 104F, and ESC stays completely cool.

This system could be geared quite a bit higher before any heating up will affect it to get a lot more top speed.

Also im worndering if you have any problems with bearing breaking off from you diff? because since i put the MM on the truck the bearings started bearking and sending thr little ball to the diffs gear so they also beaking? and im tired of that and want to buy some steel bearing and do you think the torque is beaking them. off or the rpm?

@MrOswaldo15

Your mamba monster/2200kv is already brushless. If you are breaking things in the diff, there is already too much torque. You could get a lower kv motor if you want more torque. Just use the mamba monster ESC on a lower kv motor. Don't waste your money buying an Ezrun. Plastidip (youtube it) your mamba monster ESC and make it waterproof. The motors are waterproof already. They can run happily underwater without problems. Keep the bearings clean and oiled.

do you think this combo will work if i put the esc in a waterproof case and trying it in the water or mud? because im looking for something that has a lot of torque and that is fast in the mud or water?plx help

@MrOswaldo15 There's no reason why it shouldn't work. Just leave airflow around it. The fan needs to move air so it doesn't overheat. I don't have this ESC now, it died. Get a Mamba Monster ESC, it's way better, and they are are waterproofed all the time and they keep working.

Hello

Have you tried using the pinion 19 / 62?

And if so, the brushless is fine?

Good Video.

@mnunezve

Yeah I tried it and it was OK.  Nothing gets too hot and it was a bit faster. However, that EZrun 80A is dead now. I have since switched to a MMM using the same 2350kv motor.

[MrOswaldo15]

I already have the mamba monster v3 1/8 2200kv combo and im loving it but i want something that is brushless its waterproof cheap and good torque for the e maxx?

[MrOswaldo15]

@andytheandr0id are you waiting for the mamba monster 1/8 esc or the mamba monster max for 1/10 scale cars?

[Poulpc]

no bashing at all :(

E-maxx rips!

Cool vid. I've used the 80A combo for occasional club racing my 1/8th truggy, but run 12 Nimh cells. I don't keep the fan or heatsink on the motor, and all is good for for 15 months so far. ;-)
