CC 2028 with MMM on 6s?

Was wondering, will a CC 2028 work on 6s with a MMM, or will the amp draw be too great? Was thinking of putting it in a Monster Truck.

amp draw too great

+1, I think the 17xx series is the limit for the MMM...

But I also LOVE my Mamba XL and if it was smaller I'd use it in all my RC's. It will spin up a 20xx series very nicely :-)

I was holding out on the Mamba XL cause I heard there are some bugs that still need to be ironed out by Castle. Is this not true?

Well, if your XL blows up some time in the next year, you send it in under warranty and get it replaced. If it doesn't, then all the better. Bash on.

The initial version of the XL had BEC issues that have been fixed, I.e. Version 2.
Anyone with an original XL can trade it in for the version 2, and all the current XL's in the stores are V2.


@whats_nitro, who's bashing?

mmm + 2028 = burned esc

the limit for the mmm is the 1717 ........ more is search kill the esc :(

I meant bashing, as in driving your RC in an somewhat erratic manner.

Ahh, sometimes I really overlook the obvious

I say, why not ? The amp draw doesn't depend of the motor but depends of the setup.
The motor weights 1,3kg, if its put in a monster truck of 4kg, it will do 5,3kg total weight. Geared for less than 50mph, the MMM should be totally fine, the MMM is enough to push a 5kg vehicle to more than 60mph with 6S lipo, so why not ?
More over the 2028 has a small Kv so high inductance, then the current spikes should be very low compared to other setup with smaller motors...
Just my opinion...

It has the potential to pull more amperage than the MMM can handle. It is just not a wise setup.

You could run it on a sidewinder but I wouldn't do that.

It takes amps just to spin up a larger motor. Bigger can be more efficient to a point, then it heads the other way.

I've actually been going smaller in my setups. The better motors (Neu specifically) make so much power in high voltage low KV systems that I can get insane power with tiny lipo's and light motors while retaining good run times and having the suspension run something less than the hardest springs and heaviest shock oils :-)

Just my $0.02

[nuz69]

Yeah, IMO it will be completly stupid to put this big motor in a 1/8 Monster in which a simple 1520 or 1717 will be enough... But wy not ? Ok, to turn a larger heavier rotor, it takes a little more amp than to turn a 1515 rotor, but we are not talking about 50A more, aren't we ?

Castle rates the 2028 as 10hp, or 7460 watts.

At 6s (22.2v) that takes 336 amps.

At 8s (29.6v) it takes 252 amps.

It is just not smart to mismatch components. A rock in a wheel could cause unforeseen load and the esc goes poof, or any other of a million anomalies that could happen.

Plus, as the Doc said, why have all the weight if you aren't going to use the power?


Why not put a jet engine in a honda accord?

How about a CRX?
