This is something that has been discussed but probably won't be included with the initial release, but could be easily be added with a firmware update. It is already a feature on the ICE controllers, so the software is capable of doing it, we would just need to figure out what throttle sequence would clear the data.

Turning it on at full reverse is one option, but if someone has their throttle signal reversed it could get confusing if they're doing throttle calibration; the chiming the controller makes when it's clearing the data could be confused with the full throttle calibration chimes. But I think this would be a very rare occurrence and easily troubleshot.

This may be something that Richard has already added, I'll double check at the tech support/engineering meeting on Thursday. Thanks!

When we getting logging in the other controllers, i.e. MMP or MM? Or is that even possible without hardware updates?

Not possible with the current hardware. You need the HE sensor, some memory, and extra code to utilize both.

Just an idea for "non Castle cans"

Would it be possible to allow more than 20 degree of timing on Sensorless Motors ?

like up to 25 degrees ?

Sorry, no... Sensorless is limited to about 20 degrees of maximum timing. Nothing we can do about that.

thx

was just an idea

Patrick the switch on the MMM kills the power to the microprocessor or only puts it on stand by ??

It takes down all the power supplies (including the microprocessor power supply.)

However, there are still some parts that draw a small amount of power when the switch is off -- so you can't just turn it off and leave it connected for days. It will eventually flatten your batteries.

I am running the Conversion in my Baja 5sc and I can't seem to keep the truck under control. I tried the punch control but that just feel's to me like throttle expo. It works fine but it seems like as soon as you hit half throttle the truck takes off into full wheel spin. I have had the rear tires come off the rims twice now. I am going to try torque limit next but I am not sure what setting to try first. Any suggestions would be great.

You will like the torque limiter -- it does exactly that -- limits torque.

Try starting at "4.0" and if too much torque, dial it down. If not enough torque, dial it up.

Ok Pat thanks for the reply, I will give that a try next.

So pat, any idea when this might become an option? I don't believe it has made it into the firmware as of yet.

Also on a sidenote, when you guys gonna have more mmm's in stock. Been almost 3 weeks now since you got mine in the mail and I haven't got an update yet. No hurry just curious. :whistle:

Would it be possible to get the MMM 1.24 Firmware with adjustable BEC for the V4 +

I don't like the latest 1.32 firmware, since the startup behaviour ist not really nice...

I stay on 1.24 but like to have the option to adjsut the BEC voltage

I believe Patrick said the adjustable BEC voltage was only possible due to hardware changes in the latest version of the esc, and you have to have the upto date firmware for it to work aswell. Having old firmware won't work- what you sound like you want/need is new firmware with the old start up algorithm- doubt that's possible really...

Right for the adjustable BEC you need minimum a MMM V4
I have an V5
currently i do run 1.24 because of the real bad start behavior in 1.32

So long story short, please get the old startup parameters from V 1.24 back into the next firmware please

Not impossible -- I'll need to ask Richard (our software lead) what the differences in startup between 1.24 and 1.32 are.

I'm in China right now -- will send an email to Richard and ask him to investigate.

Thanx!

thx :yipi:

That would be cool if it is possible :yes:

Just tested the latest Version of Castle Link 3.52.10
It contains the Firmware 1.38b for MMP and MMM

looks like the good old startup parameters are back.

real smooth startup !

will do some more testing tomorrow

thx Castle for working on this

Update on the latest Mamba Monster Max Firmware

the good old 1.24 allows you to start up like a crawler
On the 1.39 it is more like a "jumpstart"

the car does start instantly not really as smooth as on the 1.24

for now i stay on the 1.24

Current Limiter??
 

OK, I know I'm going to get hammered for this but what about a current limiter feature?

Yeah, yeah, yeah, I know all about the torque control feature. I also know that lots of people have reported various problems with it including some high motor temps and poor startup when trying to use the torque control feature.

I also know that there are other ESCs on the market that have a current limiter feature (and have for a long time) with none of these startup issues. Nor do you have to tell the ESC what the KV of the motor is (via a motor test) in order to use the current limiter feature.

Is this possible with the current ESC hardware? I wonder because I asked one ESC company why the current limiter in one of their ESCs is not in all the ESCs and was told that it takes up additional space inside the case.

No firmware has been as smooth as the good old 1.24 ...

I think is the torque control feature messing up the startup..

Hey Patrick, any news from Richard and that start up algorithm?
I know you're probably busy, but it's been almost half a year.
And I'd realy like to get at least one or more of the Monster 2 ESCs, but not with that sub par start up.
Because right now there are better ESCs out there and because I know that Castle once did better them selves.
Sorry to be so blunt...

Patrick ??...

:no: :cry:

1.32 startup was slow and gutless on my 1717. Going back to 1.28, I think it was, solved the problem.

New version of Castle Link 3.55.00 is available on the website with firmware version 1.45 for the Monster and Max Pro. From the firmware revision notes:

1.45 Beta 05/28/13
Monster and Mamba Max Pro:
Significantly increased startup torque and the delay of power from start.

Please try updating your Monsters and Monster 2's to V1.45 and please report back your findings. Thanks!

"Significantly increased startup torque and the delay of power from start."

So does this mean the start up is as soft as it once was?

No-- the opposite.

Should say: "Significantly increased startup torque. Decreased delay of power from start"

"Significantly increased startup torque. Decreased delay of power from start"
So, does THIS mean the start up is as soft as it once was?

No, it means the opposite.

It means the startup is faster and more torquey.

If you want a softer startup, you can use the link to decrease start power. This will slow down and soften the startup.

After more testing / driving i really start loving the 1.45 on my MMP

question here
are there any changes made to the fan control ?
My MMP comes off the track with about 85F but the Fan run's

There were some changes to the temperature control in the newer firmware versions. The fan will come on at a much lower temperature and the thermal protection will kick on at a bit lower temp. We actually found that on the MMP the thermal cut-off wasn't even working on some firmware versions.

Thx Thomas !

good work so far on the 1.45
i like to have the fan on sooner !

*still dreaming about 1415 .5Y*

So what firmware versions does the thermal cut off not work? I have many MMP's and rarely ever change firmware, and would like to know if I have one that should be upgraded.

Wow, should have found this thread sooner!

I've been thinking it'd be ideal to have a plug in for the balance plug into the ESC. This would allow the ESC to monitor the voltage per cell and cut off as soon as the lowest cell reaches the programed voltage. This would prevent packs from killing cells when they drift apart over time and allow the cut off to be set lower for more run time. Plus the full (full-er) cycle would help prevent the crystals from building up in the battery over time, helping them last and behave better. Every LiPo I have thrown away (witch is a lot) has been because the cells would get so far out of balance that one cell would die way before the car cut off (I have had up to a .5 volt difference in cells).

I realize this would probably bring the production cost up slightly and make the ESC slightly larger, but I know I'd buy it for sure to stop worrying about ruining batteries... But with the whole digital age and 3-4.2 volts per cell, a microprocessor should be able to read that voltage hardwired onto a pin safely. Maybe this has already been tried, maybe not, but I would have thought this would already be on the market.

I apologize if this has already been mentioned, I'm on a tight-ish schedule and out of town right now.

Can't edit post...

But I found this. Couldn't the same type thing be built inside an ESC and as soon as it's tripped, cut power?

Hi RC dude,

Sure, something like that could be built in to an ESC. Would add a bit of cost.

Even better is active cell balancing -- this is what is being used in a lot of electric (full-sized) cars today. When there is a weaker cell, power is sent from the stronger cells to the weaker cells (via a very complicated set of DC-DC converters) to keep the charge balanced throughout the discharge cycle.

I expect we'll see active charge balancers for hobby pretty soon.

Patrick

Hi Patrick could we please please have a 1/5 car ESC that can handle 12s and 300Amps.

I would really love to see that as the only thing on the market at the moment that can handle that sort of power is from MGM.

An additional temperature sensor for the motor, can be plugged in to monitor motor temperature. This way we'll be able to have a thermal shutdown if esc or motor exceeds max temps.
