When for monster maxx?

[crazyjr]

I liked to keep things up to date in case they changed something an update or two that would render the esc obsolete, due to too much change in the link to update. Honestly its been almost a year and i still haven't found setting i like, I know its in the combination, I just haven't found one i'm comfortable with

[Mr.lst]

I called castle and had a guy help me update my mamba max software and have not had any problems

[Serum]

There can't go much wrong with updating, but for some reasone more people seem to loose controllers from time to time..

[crazyjr]

As I said before, I don't know if its the program or not, but my experience tells me a certian amount of esc's will be considered a failure using the 2.23 link. One could have been a possible failure not related to the link software (ran perfectly once then lost neutral, but could still hook up to the computer), the other was a direct result of the program (while hooked up it went from one second where the software recognized but couldn't update , to not even recognizing the esc altogether) it was never unhooked or anything, it was like something wiped the processor

Like i said I don't want people to think i'm cutting down or flamming the Mamba Max, I still believe it is the best esc/combo on the market, I just think the current is not right and possibly causing some esc's to fail. Funny thing is it doesn't seem to matter the age, the ones that quit were the oldest and newest (ironicly also the only ones i didn't get from Mike)

Then, why don't you contact them( Joe)? they might help you out.

My esc fried and took the motor with it or vice versa.. i called castle and they handled it perfectly. i installed my new mamba in the truck and went off about 10minutes into my first run it thermaled.. motor temps were 139 battery at 120 and esc at 195 by the time i had body off and temp gun ready. this is stampede. its the 7700 motor but i dont understand the issues. i even have a window cut out like a nitro car. wether the gearing is 13/90 or 17/90 the esc temps are the same. all the gearing does is seem to change motor temp. im at low start power lowest timing and no drag brake with 40% punch control. im using 7 cell ib4200wc's.

With no body on it the temps are normal

The ESC is mounted on the rear shock tower.

You might get by with a fan on the esc... but it would be good to see if a setup change could help too.

wether the gearing is 13/90 or 17/90 the esc temps are the same

How much does the speed and power change? If the speeds seem similar then I would say gear down even more and see what happens.

Are you running in grass at all?

The big issue is that the 7700 motor was not designed for use in a truck like the Stampede. The ESC temp being that much higher than the motor means you are severely overgeared. You probably won't be able to get it geared properly for that vehicle unless you drop the tire size way down. I'd really suggest looking into a different motor to get the temps down. Also, just because you go with a lower kv motor, doesn't mean you can't go fast. There are at least 2 of us on the forum with 10th scale trucks running motors under 5000kv that are doing 45+ mph on 2S lipos.

Yeah, the 7700 really doesn't like to be geared. It is much more sensitive to gearing than the lower kv motors. Try a smaller pinion. If the 13T is still giving you high temps, then go to a 10T and try that. You might also want to see if you can get a bigger spur, although a 90T spur sounds pretty big already. Then go to tires, smaller diameter that is. If you can't come to a happy medium, then you'll have no choice but to go to a lower kv motor. Personally, I like the 4600. You can really "tune" performance with the battery choice on that motor. Everything from very mild on 6 nimh cells to uber wild and crazy fast on 4S lipo.

May even need to go to the 94 tooth spur

Well, I just came back from RCX, and it was a ton of fun. There was a big track inside, with jumping, racing, etc. While I was there I caught up with one of the Castle Creations Employes, and asked him about the Mamba Monster Max.

He said that the ESC is finished and now they just have to finish the motor, and then test everything. He said the esc will about about the same size as the Mamba Max esc, and will be rated for 5s lipo. However, he didn't mention anything about an HV model to allow more voltage, although it may still happen. He also said that it should be out in 3 - 4 months now or late Summer instead of early Summer, like they said before. :019:

Unfortunately, stupid me forgot to ask about how much it will cost. I am pretty sure MetalMan also went, so he may be able to give a little more info.

[crazyjr]

Thanks for the info. Despite my rants earlier, I'll probably get in line for this one as well. If 2.23 takes it out i can always send it in

[BrianG]

Oh, for crying out loud! We have enough ESC's capable of 5s already. Even the MM can do it (sort of). We need 8s+ with the current handling to go along with it.

I agree, but if they say 5s it should handle 7 or 8s lipo's for sure, Who knows, we might finally get a bec that can handle 5s without a ubec. 5s is enough for me, I'd rather have a bec in the esc that can handle the load. I also want a Mamba that can handle 4+pole motors over 6+s

[BP-Revo]

I talked to Joe and the other Castle engineer/developer at RCX today and they said the MMM should be out in ~3 months. They said the ESC is just about done, but they are working on the motor (but I think this has already been said).

However, what I do not beleive has been said is that it will have an integrated switching BEC, like the one seen here, that can handle 7 amps continuous and 10 amps peak (like anyone really needs that) and will have an adjustable voltage output. Downside is that he said it will be rated only for 5S (would have liked to see 6S if you ask me), but that they will do an HV one later on that will handle more (probably 12S).
