My concern is that if for some reason I need new wires for another project, I can just solder some up, or plug them in as what I could do with the unit that has the plugs.

Thats pretty much it. I think its great you guys are getting on these issues.


Now, just need a ROAR legal brushless system from you and I am set! :)

Got it. :) The only reason we released the MMM with wires was because we didn't have the SMT bullets ready yet...

About ROAR -- well, we'll see. There are VERY serious issues with the ROAR rules.

Yeah, 3X6 would be big, but not really in relation to whatever would require that kind of power. It would be large in an 8-10th scale, but not so bad in a 5th scale or larger.

When are you gonna start making car ESCs... meaning real 1:1 cars?

Patrick, I will try to be constructive, all this brains-transfer business start when you had first generation of MM, with great software but "Ok" layout. Latest version with new layout and new fets doesn't need anything besides couple components, improved heatsinking and software to perform on MMM level. And I mentioned alot that with that layout you did the best for 4-6S setups. And just software upgrade to support 5-6S will do the job. While MMM with just extra 6 fets and all on top, with pathetic cooling just make me believe that all the input from RC forums for small foot print and no fans was ignored. Thank you for switching BEC, though, I understand sometimes you need to iron out some bugs.

I would rather use your product, other than making it to work close to MGM level. You have the best price, software and service but MGM has nice hardware...

And I am not biased on Castle products, I do like what works the best and easy to use.

So, for now I do not see any challenge to make ESC in MM or Tekin R1Pro size with 6S support (30V Fet's protected and adequately heatsinked) and ~100A current capacity.
While 3x6 sounds interesting but at 20S and 250A I will go with different controller...

What's constructive about being intentionally insulting, and calling people stupid? Until that last post, I thought it might be a cultural thing. Thank you for clearing it up for me.

I'm looking forward to seeing your designs on the hobby store shelves.

I can put my sticker on modded MambaMax controllers? :)

Sure. We could even change the caps and add the TVS for you.

you might as well except for Brian and a few others nobody has a clue as to what you and Patrick are talking about......:-)

MOnSterFET.....

Ever thought about a sensored esc? Stick a hall sensor do-da like the novaks use on the end of your Castle-Neu motors (it really is that simple, honest ) and hey presto, the holy grail of BL escs and motors = sensored smoothness, zero cogging, locked rotor detection etc etc and a truelly awesome motor to match.

If you build it, we will come!

[lutach]

Kind of what Aveox did back in the days.

And lower efficiency, lower reliability, inferior locked rotor detection, no automatic timing...

Who's hype have you been listening to?

What about a hybrid system like the Speed Passion GT ESC? That takes advantage of the sensored starts, but can still do the automatic timing. I never heard of a sensored motor having lower efficiency; if anything, I've noticed that they run cooler for the revs they have to spin (I know they don't put out THAT much power, but they're no slouches- especially once you get into the lower turns).

If someone could put out a sensored system that can deal out the amount of power your guys' system puts out, I think it'd be a hit (screw ROAR... I could care less if it's ROAR legal). I'm pretty happy with my Mamba Max and Medusa setup though.

Methinks I need a CC BEC so I can run 3s happily all day.

Yeah, sensorless systems are significantly more efficient. The reason is that the controller can vary timing based on RPM, load, etc. and uses the OPTIMUM timing at all loads and RPMs.

With the sensorless startup algorithm we have, there is no need for sensors unless you are doing something like rock crawling -- so why have the reliability issues of the additional wiring harness and PCB, AND the additional cost?

Don't fall for the BS Hype -- sensored is worse in almost every way.

Now for rock crawling, where the motor needs to have torque when not rotating, sensored has a slight advantage.

You missed my point about the Speed Passion GT ESC though. It combines both worlds. Apparently, if you run something like a Novak on this ESC, it runs far better due to the variations in timing that the ESC can select, like you say.

I don't understand how having sensors creates reliability issues? I have an original SS5800 motor that's still going strong. It's been run on anything from 6 cell Nimh to 2s lipo to 12 cell Nimh. No problems yet and the motor has to be a few years old. I've read of the odd problem with a Novak motor here and there, but in comparison to some other motor issues, it's not NEAR as prevalent. Sure, more parts means a higher chance of failure, but for the sheer amount of motors they have out, I've only heard of a few reports where the motor was messed up due to sensors.

Yeah, its sad they left the RC game- before my time really, otherwise I might have bought one of their systems to use instead of the hvmaxx. Concidering I paid a barmy £269/ $510 for the system (yes, that much!), I think I could have done alot better, if only I had found RCMonster earlier in my RC career....

[TexasSP]

Sensored motor setups or great for CNC servo motors (and others that need high precision) but I see no need for RC applications were that kind of precision is pointless. As smooth as the MMM is I see no reason to toss a sensor in their, it is every bit as smooth as the novak ESC's and way more powerful.
