Mamba Max 10th Scale Power System

The ONLY Brushless System To Own!

Are you SERIOUS about power or just into having SERIOUS FUN? We 've got you covered either way:

so a few months ago I ordered one.... runs great in my FLM rustler... so I was thinking of putting one in my other truck... I do have heat issues which kinda suck... after a 10 min run (or 5-7 min run full out) I have to let it sit for a bit to cool off...

then I read at the bottom of the page...

NOTE: The Mamba Max Power System is NOT for use in 1/10th scale monster trucks.

it is great for 1/10th trucks, buggies and cars.
but its not for the e-maxx, revo conversion, etc.

According to CC its not intended for Monster truck size applications. Many here have proven it capable, but they are trying to cover thier butts with conservative specs on it. They want to be able to claim that as long as you follow the specs it is pretty much bullet proof. I personally dont think you could smoke one if you followed the CC specs to the letter.

You could easily smoke one following thier rules.

12 cells, any of their motors, on a heavy e-maxx = smoke. Gearing will be a mojor factor in how long it takes to smoke. Trust me. Out of at least 15 esc's I have smoked, only 1 of them was out of spec. But ya, Castle is by far the best...but wrong application will end its life early. If you are gunna try it, try it with a castle....its the most likely to survive.

You've burned 15 ESCs?! :eek: You ought to change your name from Bomb-Proof to "sparky" or something. :dft012:

yea, no kidding. The best one was at the last RCCA race in CT, I smoked out the nitro guys in the pits.....massive amounts of smoke. The least fun is when a lipo is involved.

The manual says not for 1/10 scale monster trucks. Emaxx is a 1/10 scale monster truck. Hence, not within their specs.

I can smoke it in anything, trust me.

Serum · 02.17.2007, 07:45 PM

schulze succeeded in compressing the biggest amount of smoke..

They make better smoke machines than controllers..

BrianG · 02.17.2007, 07:50 PM

Has anyone figured out why Schulze ESCs burn so easily?

glassdoctor · 02.17.2007, 07:56 PM

So all those 80's rock concerts really just had a few schulze escs planted near the stage... :D

BrianG · 02.17.2007, 07:57 PM

Expensive effects!

Serum · 02.17.2007, 08:01 PM

Yeah, schulze did.. Loose contact!!!!!!!!!!

i personally think it's because of the motor braking, which can causes higher spikes. a fet is allergic for that, as you know.. :) there are some kind of diodes, you can buy at a set voltage (lets say 24V, and anything above that 24V is killed (regulated till 24V). can't recall their name.. but they can handle an awfull lot of power.. and you can put them paralel over the source. (motorwires in this case) so three of them.. never tried them, but i am pretty sure you will keep the fetts in their safe range..

BrianG · 02.17.2007, 08:11 PM

Hmm. Most FETs have the diode you are talking about integrated into the FET package. As to the name of the diode: Are you thinking "avalanche diode" or "zener diode"?

monel_funkawitz · 02.28.2007, 12:59 AM

I may be a fairly new member, but I have alot of electrical knowledge that I can share.

Zener diodes are what Serum is referring to. They act like a normal diode until their specified or higher voltage, then they conduct. Unfortunately, they have a slow "response" time to conduct. That time delay still creates spikes.

Schottky diodes conduct ultra fast, but conduct like a normal diode. They conduct one direction, but not the other. Not good for speed controls that have reverse, cause you will have a short on reverse.

The best thing I've found to use on most little motors is something really simple and cheap. It can usually be found for free, conducts at around 80 volts, and is bi-directional..... a neon bulb. You solder it across the motor terminals. Simple, but it works.
