Mamba max Vs 9920, Your vote.
 

Before I order my new esc for the emaxx, I just wanted to get some opinions on these two entry level speedys.

I'll probably be only running Nimh packs, 12 -14 cells and 7xl motor with UBEC.

Which would you buy? $180 Vs $140?

For anything over 12 cells, I'd go 9920 for reliability.

I've had both and I'd go with the mamba max for the cell count you listed..

Mamba max all the way, I have two running on 4s and 5s lipo's and they run good

Mamba Max by far.

The MM can stand up to 5S lipo (some have even run 6S!!), so it should handle 14 cells fine - plus, its rated for 12 cells already.

Castle themselves have said it will handle 14 cells, as long as you disable the internal BEC and use an external one. My vote also goes for the Mamba Max. Here's why:
-less expensive (I can get them for $100, normally $135-140)
-MUCH more adjustable
-smoother
-smaller
-better customer support (BK's has been terrible for me)

Amen on all counts.

BP Revo, the 6s is A123 cells which is equivilent to about 5.5 s lipo

Mamba Max for me. I can still see buying a 9920 if you need a cheap controller for high voltage though.

Who ran 6s? Mine fried on 5s. I dont buy it.



Just buy a 2 pole motor with either one of them. I know some will argue with me that it works great, but In my experience the MM doesnt run the Neu 4 pole motors well (at least not as well enough for me) and its common knowledge that the 9920 doesnt run 4 pole either.

9920 was intended for an emaxx size application. The MM was not. The MM performs well for what it is, but IMO the 9920 is the more appropriate choice for a monster truck. You can upgrade to the MMM when it comes out. Of course the support on the MM is FAR superior to the 9920. Its a tough one to call. They both have there ups and downs.

cart123 did 6s A123.

A123 is a different story. I still doubt it would run like that for long. 5s (lipo) seems to be the limit, (and pushing that limit.) The MM on 14 cells is more realistic for an everyday setup.


I just dont want to see people reading that and thinking it can run 6s. Some are obviously confused already.

And to think I almost ordered the 9920 ...:005:

That wasn't me, I think it was Cart123, I'm running 5s of maxamps 8000mah lipo's on both of mine

Woops. For some reason the letter c at the beginning of both of your names confuses me, and it seems I never know who is who. It's fixed.

ok, no problem, remember he has the bl truggy i don't....yet

yeah, the MMaxx controller is wicked. it's got tons of programming features, and it programms with the ease of breathing...

It's small footprint plus the awesome support from CC, make it an easy call on 14 cells..

Well slap me with a piece of cheese!

I was basing my post on what I'd heard about the MM dying on 5S. I suppose 14 cells isn't quite all the way to 5S. Count me in as learning something new today. I'm going to do some speed runs tomorrow...and hmmmmm, i have two 7 cell packs. :)

sleeb,

I dont disagree with yur post. I think that it will be more reliable on the 9920 for anything over 12 cells. But 14 cells has shown to be stable for many. 5s is hit or miss. some are sucessful, some are not.

I have heard the new update makes them alot smoother on the multi pole motors.
For the mm that is. It would depend on the future plans of esc.
MOre voltage 9920
Same I would go mm

Sleebus, don't tempt me, after all, i am in Holland, land of the cheese..

Have you heard when it is supposed to be out? I know they are supposed to be working on it, but no ETA as of yet that I have heard. Just that its ''In the works''.

That update would be a HUGE thing for the MM.

I read on the crawler forum it had a big improvement.

So its out now? WHen was it released? Sometime in the last few days?

It's not on the castle site yet, and with the mamba 25 they even posted the beta versions on their site..

I called to ask last week and they couldnt tell me an estimated time. Just that it was on the list of to do's for the MM. It didnt sound like it was going to be in the very near future. More like months rather than days or weeks. I could be wrong though. Just a cutomer service guy I was talking to.

Hehe, oddly enough I lived in holland in the late 70's. Went to school at the international school of Amsterdam, we had a townhome in Haarlem. The company I work for has an office in Haarlem, actually. Maybe one day I'll get a trip over there and you can personally whack me with some cheese. Gouda is one of my favorites. Smakelijk!

Mamba Maxx is my vote no need to explain why they already did it for me

Sleebus....LMAO....Slap me with a piece of cheese! Now there's a quote! :005:

Can I use that?????



I vote mamba Maxx Too!

WTF, there: http://www.castlecreations.com/products/mamba_max.html read can use ONLY 12 NiCad/NiMH cell, or 2-3s LiPo, is that true or not? Many guys in here use more than 12 NiCad/NiMH or 2-3s LiPos, what is point in this thing? Why there: http://www.castlecreations.com/products/mamba_max.html read can use only 12 NiCad/NiMH cells or 2-3s LiPos, if can use more??? I cant understand... Im gone crazy... Here in Finland anyone dont use more celss with MM... LOL !

You most certainly may! :027:

Sleebus

Yeah!

Thanks Sleebus! :005:

Can't wait to go out and use it somewhere! :005:

All in the set up my man, all in the set up!

But im suprised... I have think if use more celss than Castle Creations site read, controller get smoked. But if i can use 4-5s LiPo without smoked, i buy some other LiPo than Max Amps 11.1v 8000mAh:dft009:

It's mainly the bec in the esc. what the guys are doing is using an external bec called a ubec. This will allow more voltage to be run through the esc. You do need to watch temps and what not though, make sure your gea ing is right. There are limitations to everything of course. Also, I think if you are running more than 4s is voiding warranty. But yes, it can be done.

And when we are running 4s lipo we also are normally using a lower kv motor than you would on 2s or 3s. The end result is that the 4s setup is actually easier on the MM.

But as mentioned, you need to bypass the on-board bec to make it work.

Exactly, a 7xl has a lower kv rating than the mm motors.

That mean i can use 4s LiPo (16.8v in charged) with UBEC, 7xl motor and MM controller without smoked (smoked is possible still, i know it.) ?

Pretty much, yes. Sweet, huh? :)

I'm running 5s lipo's in mine(21volts full charge) in mine with no troubles, I haven't had a chance to run the 7XL for a long time and see how hot it gets, but its has wicked power

Excuse the minor thread highjack. Is there a "tame" motor you could pair with the MM to give comparable performance to the original Titans? Would something like a 9L with 3S work? Ideally would like to avoid having to use a UBEC. Looking for reliability and runtime vs. insane power.
