That could've been the punch control which cuts the voltage. I've said about this brake issue for a long time. The timing causes this delay from high speed. Theres not much you can do about it, if you use high timing. I drive a lot with the brakes and had to change my style with this esc and thats not good on a very tight track.

I think this esc is potentially great outdoors, but i've had enough of 'potential'. I'm waiting for updates for the drivability and Castle are not responding. It would be nice if they kept in touch on rctech more. Even Hobbywing reply to customers on rctech super quick without them being asked for help directly.

I don't want to dig the knife in too deep, as this esc is very cheap and performs well for the price, but as Hobbywing have proven, their frequent updates have turned a 'cheap esc' into a rocket.

Nothing keeps people more faithful than regular responses from the factory or factory drivers. Tekin is the proof of this. They had a large and loyal following long before their famous V203 was released. All because every day Randy kept people up to date.

The thing I have never understood is why the other manufactures can't see what is so blatantly obvious and choose to do the same?

Pablo Diablo, Castle is not sleeping I believe. And I hope. They should be by now moving to bigger instalations.

"racers" asked a smaller ESC, as far as I know they are working on that.

Here, so far, we did not felt that lack of drivability of the MMP, in carpet or outdoors. Not so many races so far, is true.

I believe one of the "problems" of MMP is that we have to many options to choose from. So there is a lot of possibilities of doing mistakes.

The blue is better guys just choose between 8 or 10 factory preset programs and are happy.

Ok, I am a Castle fan, is true. When I can I use their products is true, they are top products with a fare price. But happened to me before I had to leave castle to race nacional championship because MM at that time was not good with sensored motors allowed. Not a problem of MM, a problem of rules. but happened.

I understand you are a very interested person, doing a lot for a car I like a lot, the Type-R, so I understand you want the best things every time.

Let us wait a bit longer. And I am glad a person like you is interested in makeing the Castle products better.

I agree I think we will see some improvements here pretty soon. As for the smaller footprint, the mamba is no bigger than the SP or GM controller. Just the case extends over the solder connections on the board. Really the only thing that they should change to the current version is include the option to get it with solder posts. I would pay the difference if it just came with them. And if they do make other changes, then the sensor connector should face up, being on the bottom like the KO BMC makes the plug really hard to get to. Other than that I have no complaints about size.

As for drive-ability, if the power is too intense, just adjust between gearing and timing. This really doesn't seem so different from the brushed motor days where I would purposely over gear a little in the 19T class to make the car smoother. If things got too hot we added fans. So if you want the speed down the straight but a softer bottom then just lower your FDR and reduce the timing to keep the heat down. The mamba is fast and there is no reason to be giving your motor 50* advance timing unless you are out doors and totally wound out before the end of the straight.

Unlike Tekin which I would say 75% of their business is racers but Castle isn't like that and compared to Tekin makes hundreds more products so trying to get to all the sites to post on everything they make is next to impossible.

Racing is just a very tiny part of what Castle does and what they make esc's for. Are local shop also sells hundreds of airplane speedos from them so can't speak for all companies but Castle is way more than just racing unlike some brands that their reputation is mainly for racing only.

With the giant Castle product line it is impossible to be on every website all the time posting. I'm sure they would love to have that many more employees that would have the time to sit and post on every forum that has a Castle thread. Just isn't realistic.

I understand your point, however there have been lots of Castle representatives responding to posts about a month ago and before, yet it seems they've all dissapeared. I'd be surprised that all of them have no time to have a look on here.

Well never thought it'd happen but my MMP is now in my spares box replaced by the cheap Chinese rubbish XeRun.

I'd have happily sacrificed some speed for smooth power delivery, but the XeRun now runs faster and smoother than my MMP.

Sad state of affairs really as one MMP failed the other week and had to be returned, the other one has now been replaced by a better running Esc that cost over 1/2 as much.


Lets hope CC bring out some updated software shortly and get this cogging problem sorted.
Otherwise the MMP's will go on ebay to be replaced by XeRuns




Cheers
Mark

When they are in between new product runs then they do try to check in some of the sites but overall just way too many to keep up with. If they had such a small product line like some ESC companies it would be easy.

I guess I'm lost on the no smooth enough thing. I ran all kinds of brushed and brushless motors on the MMP and it is easy to make it as smooth or and quick as one would like on the throttle. Not sure why some can't figure it out.

Funny thing is guys wanted a speedo with lots of punch but yet complain about it having too much punch and not smooth enough for them. I can't figure some of you out.

If your using 100% punch control you doing something wrong. You will have like no throttle response down low and then it will hit all at once so its no wonder why its no smooth.

We sold about 70 MMP's for various types of racing and not one of them say its got too much punch or its not smooth enough. You just need to find the right timing and rpm range that works well and then at most change the throttle curve a little and you should easily have a smooth speedo.

@wyd , eventhough castle is busy with new products and such, surely someone can just let us know if there is any further updates coming. To say that racing is just a small part of the esc line is also no exuse, how many people have bought the MMP for racing?, i'd assume alot of people. There hasnt been any new release since almost 3 months. I'd prefer to be updated a bit, like just letting us know that they are working on some new software. Looks like i might just need to lay down $75 just to stay competitive against the HW422.

I agree entirely. I think because Castle haven't produced this esc entirely for 'racing' it is a very bad excuse for making it the reason why they're not updating or keeping us up to date. They do have factory drivers for 12th scale etc because they even designed a 1 cell racing version specifically for 12th scale and you dont use a 12th scale for bashing in a car park, believe me!

I'm afraid its the end of the road for me with this. I wont get that much for it, but it still will pay for a 60A xerun and LCD programmer. Sorry Castle, but I haven't got the patience.

I can assure you im not doing anything wrong. I've done tests with Tekin and others and you can take a lot of the sting out of those escs on an indoor carpet layout. With the Mamba Max Pro the only option you have is to make the gearing really low and take some timing away.

Punch control is next to useless, its a throttle delay! - Basically you're admitting it doesn't work as it should do. The punch control should gently build the revs up all the way.

Take too much timing away and its slow. GM has different frequency settings for starting torque etc and thats what this Mamba needs.
Just having rpm range setting is not good enough. There is a surge at the start of every timing ramp. The only way I eliminated it was starting the timing very low and having a long range (3100 - 18,700). Theres nothing wrong with 'punch' on an esc if it can be taken advantage of correctly.

As soon as I put my SPX back in yesterday, my consistentcy level was within 3 tenths of my fastest. With the Mamba I was lucky to get within 6 tenths, even with 20% throttle on the infield. It may well be great outdoors, but i've lost patience with it, thats before I even go into the brake lag at high speed.

Has Castle set a release date for the ver2 MMP?

I do agree with several others on this thread that Castle should be monitoring this thread more. I'm sure they have a few support people that could look over the thread at least once a day and provide comments. It does not take that long. Good ideas are brought up by users and could be used in future firmware updates.

Major issues are also discussed between users before someone may go directly to support, like brakes. There’s no reason the brakes could not be better with this controller.

I started this thread so by no means am I dumping the use of my MMP it would just be nice if some of these issue would be fixed a little quicker.

Hello
I have just received my MMPs and love all the talk about how much punch it has.
After reading a few pages and the guys who are jumping ship its obvious that there concern is with winning ?????.
As i said i have only just received my MMPs so it will be interesting to see how they go against the Tekin and Lrp on a long track built for 1/8 scale.
If they have as much rip as people are saying then i will be happy to jump out of the corners in front of the others. At the end of the month i will be at Tamworth track http://www.rctech.net/forum/attachme...img_5920-d.jpg as you can see this is a medium track straights around 20/25 mtrs long (70/80 feet) some tight and flowing sections , should suit the MMP.
thanks Steven.

JUST BECAUSE I DON'T POST EVERY DAY, doesn't mean I don't read this forum at least once a day. (I'm in China right now, and still reading the forums!!)

Sheesh...

For those using 100% punch control -- wtf are you thinking? That would be extremely undrivable.

We give you a couple ways to control your throttle -- 1. throttle curves (dial in a little expo in the curve maybe??) 2. Punch control (but don't just go from 0% to 100% and think it will be more drivable! Use some sense and dial it in a little at a time!)

Between those two, you should be able to customize your drivability completely -- All speedos use the same methods -- throttle curves (some are preset -- our is 100% customizable) and throttle response control (we call it "punch control".)

Now, if you want to see something different -- let me know WHAT you want to see. Saying something like "This speedo is undrivable at 100% punch control" is just saying "I don't know how to dial in a speed control"

And yes, we are continuously working on new software -- so if you want something -- ASK FOR IT, BE SPECIFIC, and if it's an bug or other specific bad behavior, tell us how to recreate it. Don't just bitch -- that doesn't help solve the issue.

Done ranting...
