Nah, You could leave those production cost adding flames off. They are pretty adolescent anyways...

Yeah, black can with green flames would mean anodize black, laser etch, anodize green -- expensive!

I say just leave them bare aluminum. Cheaper.:lol:

J57ltr 08.25.2009 05:54 PM

You really don't want bare aluminum, trust me on this.

My vote goes to black chrome. (think rustler vxl wheels)

We are releasing our own line of ROAR legal (stock type -- 10.5/13.5/17.5/21.5) motors (which MUST be two-pole, sensored, salient wound, NOVAK clones by ROAR rules...)

We are also releasing a Neu/Castle 36mm 4 pole sensorless motor which will be ROAR legal for modified. This is a Steve Neu design, similar to our MMM motors, but at Kvs more suited for 1/10th scale, and in a ROAR legal can size.


Availability -- probably Oct/Nov time frame.


nice, are the roar legal ones going to have replaceable stators like the new novak line (ballistic series) ?

Probably not replaceable stators. Bearings, rotors, sensor assembly, yes. We are not using the "screw through the can" design that Novak is using, so stator replacement is pretty much out of the question.

BrianG 08.27.2009 10:51 PM

What use would a replaceable stator be anyway? I mean, if you remove the stator (and already remove the ends and rotor), you are left with just a cyclindrical shell. I can't imagine the replacement cost of the stator/shell is much more that just a stator...

BrianG if you look at novaks new series it will all make sense. Basically if you were doing a spec class you buy one motor and then just buy a wound stator for the other turns you want. That way you spend about $30 for each different turn instead of $90 a pop for each turn you might need.

Thats.... actually quite cool how you can do that- for racing it makes sense.

Shame it wouldnt be so simple if you fried the stator, as most times the rotor has become demagnetized at the same time due excessive temps- new rotor and stator wouldnt be much cheaper than a whole new motor I think is the point. But for racing, a $30 stator assembly is alot cheaper than a whole new motor in order to change your motor class for racing.

I happen to be in the market for a speedo to go in my B44, and I am running sensored in it because of the smoothness of the novak systems.


What i want to know is, is the Mamba Pro as smooth as the novak systems, and will it play nicely with the novak motors?

I am currently running a 5.5 on a mamba max( I know ), because my old novak wont handle a 5.5.

One if the things that I have noticed is the castle systems seem to have a really low current limitation, the mamba monster is 120, the mamba max is 100, but my XBR is 120 and a GTB is 540, does anyone know if there is a reason behind this or can the novaks just handle more.

Not Bashing Castle I just want a good racing speedo and those are some of the things to consider.

Novak over specs on the AMP rating trying to get people to buy it just because they see a big number on it. Castle rates their ESC n real rating of the MOSFETs. Going by some pictures of the GTB's MOSFET, the ESC is only rated for around 60-90A depending on the MOSFET used. Don't fall for over rated ESC.

snellemin 08.31.2009 12:22 PM

Castle list true power numbers, compared to Novak.

dunno about novak motors, but the mamba max runs my sensored based motors nicely with the latest firmware. BTW, I run a 2.5T on the mamba max.

J57ltr 08.31.2009 12:31 PM

Basically it boils down to the ratings that they use. MOSFETS have several ratings some are continuous and others are pulsed. The pulsed rating is the higher of the 2. Temp plays a part in it as well that's why there is a derating curve for the Fets. The hotter they get the less efficient and power they can handle. If you look at that I think that Novak rates theirs based on Burst current. If you look at the MMM it's rated at 120A but the burst current was somewhere near 1000A.

I seriously doubt any of the speed controls will handle what they are rated anyway. If you draw 100A at 12V on a MM I doubt it would last more than a few minutes. Same with the MMM If you were to load it at 22V and 120A even with the fan in an A/C room set at 72F it wouldn't last more than half an hour. Granted these things run off of batteries, but to me a continuous rating it just that...

Yeah i didnt think that the GTB can really handle 540 amps cont.

My 5.5 runs decently on a mamba max, but not nearly as smooth as it was with a borrowed GTB, obviously because of the sensored, but will the mamba pro be the as smooth though?

Also the mamba gets REALLY hot on a 5.5
