My MMMv3 & 2200 Combo is TOPS! - RC-Monster Forums

littlejohn · **My MMMv3 & 2200 Combo is TOPS! -** 07.13.2009, 09:30 PM

With all these threads about MMM going up in smoke. I thought I'd try to shed a balanced perspective on things.
I have 2 MMMv3 2200 combos, one in my ERBE and one in me 8ight-E. Both have been running awesome, the ERBE has never even had the fan go on, and the 2200 has never been more than warm to touch.
The 8ight-E did have period where the fan was coming on for a bit and the 2200 was getting hot to touch. But that was when I was playing around with pinions. Now the MMMv3 in my 8ight hardly ever has the fan running. I often switch it off then on again at the end of a pack to make sure the fan still works.

My setups are as follows
ERBE
SMC CMAX 40C 4s & Tanic 6s 35c
18/54 pinion/spur
Losi 8ight-T wheel & XTT combo

8ight-E
SMC CMAX 40C 4s, Losi 25C 5s & Tanic 35C 5s
15/45 pinion/spur
Proline Bowties v3

Cheers,

Glad to see someone post up their good luck. I just sold my e-revo that had a v3 mmm in it with about 50 hours of use on 5s and never a hickup. I have a mmmv3.1 in my RC8T that has seen about 10 hours of track and an hour or two bashing before the race season started and no problems with that either

Just goes to show size does matter!! My unit failed with a 15+lbs truck!!

True, in my bog stock Savage Flux, the ESC fan does come on quite a bit, which is why I only use 4s on it.

littlejohn · 07.13.2009, 10:05 PM

Guys that are running heavier cars/trucks... what motors are you running?
I would imagine a really low Kv with 6s would be the ticket.
IMO, I think a savage / 15+lb truck with a 2200Kv motor is undersized.

Edit: unless geared appropriately.

fastbaja5b · 07.13.2009, 10:19 PM

The Savage Flux comes stock with a CC2200 geared 20/44

If anything the Truck is overpowered even on 4s.

Come on guys this was supposed to be a thread about success, not another one about Monsters failing in heavy trucks geared for high speeds.

the reason the fan comes on is because you dont gear your truck the right way any higher..

I love my 2200.. The motor could stand an upgrade though- i have the Pre production traxxas edition without the wire shrouds etc..

still running liek a champ in my converted revo

This doesn't mean that it's geared correctly.....

Edit: 20/44 is good for doing standing backflips..... I can get me ERBE to do that too... but I would consider that abuse ;-) just my 2c. Infact the rollout at 20/44 on the savage is way taller than my 8ight.. Not a surprise that Savages are smoking ESCs....

fastbaja5b · 07.14.2009, 12:06 AM

It's geared for 35-40mph, the motor has never been above 140f, the packs have never come off more than warm and the ESC has never temp'd over 100f after a run.

And that's not geared correctly?!?

Welll then.. I guess we can add you to the tally of another happy CC user??
:P

As I said, so far so good with mine, yes the Fan does come on, quite a bit actually, and no I won't be piling more than 4s lipo in it given the failure rate of the MMM above 4s lipo, but besides a noisy fan it's been fine.

Snipin_Willy · 07.14.2009, 01:02 AM

Besides the fan takinga dump on me, my MMM has been great (2nd one). Even with the fan not working it hasn't thermaled (knocks on wood).

PDM · 07.14.2009, 06:21 AM

I have a combo with 2650kv motor running on 4S.

My fan stoped, put some oil in the bearing and is working again.

12 hours of track, and beside that situation with the fan,

So far so good

shaunjohnson · 07.14.2009, 09:25 AM

my MMM has been buried in mud and environmentaly been treated rather roughly...
yet it's cranking out 45mph on 6s in my revo at the track and is coming 3rd consistently (although all the other cars i race against also run 6s and MMM's LOL)
great ESC and i really cant see why people are having so much trouble...i guess i'm a wimp when it comes to power hehe

castle, thanks for the creation of the mamba max, mamba 25 and the MMM, all of which revolutionised the RC industry, and thanks for having the best customer service EVER.
