Record of MMM V2 success so far

[macr0w]

My first v2 Dropped dead after about 4-5 hours of total track time. Maybe a bit more.

It just stopped. No smoke, no flames, no lights, no nothing. Just dead.

Config: Mugen MBX-5 Prospec, 1512/1.5/D/F, 11t pinion - 46t spur on 4s 25c 5000mah Polyquest.

Mods: Holes drilled in case at the caps, Fan wire shrink wrapped and rerouted.

Runtime: About 4-5 hours.

Driving Style: Drunken Barbarian with Terets and dirty contacts.

Other: Temps were fairly consistent around 145 degrees.

Number 2 v2 is still holding up. I moved it from my truggy over to the buggy so I could race it this past weekend. I put my old modded up MM back in the truggy. It ran pretty good too.

Just got mine up and running(finally). Had to wait on a pinion that was big enough for my shaft...

1) What configuration ?
E-Revo, Hobbycity 8XL(1700kv), 4S TRC 15C/8000mAh lipo

2) Any mods ?
24/58 gearing, 50wt shock oil, blue/silver springs, TRX anti-roll bars, alternate steering block for better steering, Spektrum DX 2.0

3) How long the run time so far ?
5 minutes so far

4) Driving style
So far, "sissying" it to make sure all is working well and then I'll be getting barbaric on it, for sure.

5) Any other relevant info.
During calibration, the MMM wouldn't register the brakes until I puched from the back of the trigger for another half mm of travel...then it registered. After running for a few minutes, I went through my EPA settings and noticed that the brake EPA has to be set individually from the throttle.
I'll be messing around with the hardware installation as it's kinda just thrown together to get it going and make sure everything works.
I'll post again once I've been able to finalize the setup and recalibrate the ESC, dial in the settings etc.

Nice idea to have a positive thread like this considering all of the negativity due to failures and the typically silent happy customer phenomenon. :)
Hopefully I won't be posting in the MMM = fail threads. (crosses fingers)

Update: the MMMv1 is still running strong. The MMMv2 died while racing last night. It didn't go up in flames or anything, but there was a distinct burned electronics smell to it.

Please forgive me, I couldn't help myself. I'm on a weeks annual leave and suffered a momentary relapse of no MMM rage.

[SunnyHouTX]

1) What configuration ? vehicle = Hot Bodies LSP-R, motor = KD 36-74 9XL (gone bad due to running on 8S previously), battery = 5S Hyperion LCX 5350
2) Any mods ? None
3) How long the run time so far ? 10 minutes or so on Truggy. Soon to be on the good ol' Rustler on 6S and Medusa 36-50-3300V2-5
4) Driving style = pretty brutal on electronic components
5) Any other relevant info = Originally intended for the Truggy and will go back into it after the ROSSA speed challenge and when the Medusa 36-70-1600V2-5 comes out

So far, I have no complaints on the MMM.

Edit: Now in Rustler on 6S running the Medusa Motor. Works like a charm! Going for speed runs this weekend.

[MTBikerTim]

Well I'm on a roll. I really hope that the early failures are just manufacturing defects.

1) Configuration: FLM Forward tranny Savage, Neu 6s 20c 4900mah battery, Feigao 11xl 1516kv, Hitec 5955tg steering servo, Hitec digital high speed brake servo (can't remember number), Max size wheels, geared for 30mph in first and 40mph in second.

2) Mods: No mods on the MMMs

3) Run times: A few minutes

4) Driving style: So far sissy haven't had a chance to flog them, they don't last that long.

5) Story:

So I killed an MMMv1 had it repaired and killed it again. I have now killed two v2s as well. I can't complain because castle is sending me another one.

MMMv2 number 1
Died on the bench with the car propped up with out the wheels on. I was checking steering end points (all ready setup but I was checking), calibrating the esc and just checking the car over and it switched off. Gone.

I was running an eagle tree on it while it was on the bench and the highest amp spike I got was 10 amps or so. It was only that high because I think I applied a little bit of brake by hand once.

MMMv2 number 2
Installed and ran it with out the brake servo connected as the brake servo is the only thing running off the internal bec that hasn't been run in another car. Ran it round in front of the house for a few minutes and it worked fine.
Next night I put in a better brake servo and took it out for a bit of a test in front of the house, all was good. I then took it to a school parking lot where I would have a bit more space to wind it out. The car was insanely fast and having second gear kick in really late seemed to be working well. Was driving it around for a few minutes checking the temps every now and then. I stopped it (esc still on) and did a thorough check of all the temps servos, battery, wires, connectors, motor, MMM fan was off and everything was dead cold. Went to take off and the car switched off. Gone.

On this esc I didn't use the eagle tree as I wasn't sure if that was causing the problem and from my other runs it didn't seem to be pulling too many amps at least in first anyway.

Small Update: Castle has the best customer service ever. They are sending me a replacement and I am buying another 2 MMMs for spares. When the replacement gets here I will run it with an external bec.

[joeling]

Keep it coming guys. Those who posted earlier, please wait a week or two & report back on the status of your esc thanks.

As for me, not long now. Hopefully by this weekend I'll have something to report...

Joe Ling
