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 !

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.

[neweuser]

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.) ?

[glassdoctor]

Pretty much, yes. Sweet, huh? :)

[crazyjr]

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.

I ran 3S on my 7XL, and that's good fun. Light, nimble and about the same power than the titans.

Thanks, exactly the kind of info I was looking for.

With the stock Titans it will flip on it's lid from a standstill...plenty of power for my purposes.

Do you think a 9L or 8L would be sufficient in torque and not have a heat issue if I gear it down...not for top end speed. Speaking of that, what gearing should I go for....12/72?...and what is a good source for 5mm pinions?

By the way, my E-Maxx is pretty close to bone stock...except for wider offset wheels which really cut down on rollovers. The biggest bummer for me and the kids is swapping out batteries every 10 minutes...if they last that long. Would love it if I could see 20-30 minute runtimes. Which 3S batteries have you had the most success with? Have you ran a pair in parallel for extended runtimes?

I would go for a 7Xl, not a 9L

Thanks. Looks like the 7XL is capable of generating about 20% more torque than the 9L at the same efficiency....should run cooler. It also has way more headroom...if I do decide to push it harder down the road.

Running 5s is pretty hard on the MM. I've ran mine w/ 5s since Oct., but I did let my wife drive it for a minute and she managed to smoke it. ;)

It is insanely fast tho. When I was driving it I didn't have any problems, but I didn't drive in thick grass or any really challenging terrain either. (Late fall I did run it on the dead, brown grass w/o probs, summer heat and thick grass is a no-no.)

4s is a great amount of power, and 5s is really nice, but is def on the edge of what the little 1/10 esc can handle. Best bet is to go 4S or wait for a bigger controller for 5S+.
