I guess all sensored escs are the same "smoothness" (did I spell that right?) :p

foremi11 08.31.2009 02:21 PM

I'm probably just overthinking it

Plus i think from the racing side pc programming is a plus, and it is sensored so it should be smooth enough.


What was it someone said about a feature were it raises the kv of the motor?

Not necessarily true. Firmware and processing speed will still have an effect on the outcome.

The thing about sensors is that they are only useful at 0-low rpm's, once higher emf feedback works better. Castle takes so much type tweaking their firmware I would believe that they will be far superior with the sensored MM Pro as well. Not too mention that it is programmable to a degree not seen on any novak ESC's.

Is the MM pro going to be running cooler than the original MM say in the same setup?

Do we have any new updates on release date?

most likely. newer components are usually more efficient...

I agree, but the temps i see on the mamba max after a 5 minute race are extremely hot. I don't know what it is but it just does not like my 5.5. The motor never gets above 150 in 5 minutes, and I have the timing just below average and the start power on high, but it will easily reach 180 or 190 in a race without a fan.

Hopefully the mamba pro is A LOT better with the heat, I plan on buying one, just waiting to see what the initial response is towards them.

Sounds more like a setup problem than the ESC is bad with heat - I've been running them in all kinds of cars from my lightening 2 buggy, revo conversion, erevo, rustler, and never had heat problems... what's the rest of your setup like? voltage? how many kv is a 5.5?

Novak specs their 5.5 at 7,400 RPM/volt:

Sorry if I wasn't clear, but a Novak 5.5 ( around 7400 I think), I am running it on a Reedy 4800mah 2s lipo, and the gearing is 18/84. The gearing does not seem to be the problem because i have tried raising and lowering the pinion size and it does not help. I have run this car off of two mamba max's and they both ran hot. This motor ran fine on the GTB and My XBR and 8.5 never ran hot.

The only thing I can think of is something is binding, but i have checked and rechecked the bearings and my diff shimming and gear mesh's and they are all fine.

I REALLY do think it is the mamba's, because they are both fine, just run hot on that particular motor.

novak 5.5 has to be less then that if I'm not mistaken.. My 36mm quark 4t motor is supposed to be 6000kv.

Edit- whoops, that was a very n00b thing of me to say. Guess it all depends on more factors then turns...

The novak 5.5t ballistic motor is 7400kv, as stated in the previous post.

BlackedOutREVO 09.01.2009 10:11 PM

That sounds right on the KV. a 3.5 is right around 10,000 KV

I ran a 5.5 in my wheeler for months. And it never got hot, esc or motor (orion motor, and a LRP sphere, then a KO esc after) im not sure how your ESC is getting so hot

foremi11 09.01.2009 10:18 PM

Yeah, I dont either. I HOPE there not something wrong with my speedo.

My mamba max (was using yeah racing 60A brushless esc) dropped the temp on my yeahracing 5.5 T 6000kv motor from over 60C to 48C with higher power output (higher speed and acceleration), better response (nothing to do with settings. Max setting/reducing timing on the YR esc doesn't even compare to the MM) and the thing that amazed me is how smooth the throttle is!!! My buggy can crawl at like 2 mph with no cogging using the slotted motor. I wonder how much smoother can a sensored system get. The down side is that it seems to be running a little hot even on 2S lipo. It is supposed to be rated at 100A continuous right? I don't see how the MM can do 100A cont without any advance cooling.

Hmm.. where do you stay? What's the ambient temp like?
