Mamba Pro - for all you tech-heads
 

Here is the now obsolete Rev C Mamba Pro control board.

Thought the tech-heads might be interested in seeing it. Rev D was ordered today.

94 parts in less than 1sq/in. Switching BEC, sensors and sensorless control circuits, 2 switching power supplies, 2 linear power supplies, three phase bridge drivers, up to 100 mips processor capable (50 mips shown.)

That's a US quarter by the side there...

You hand soldered all of that right?

Should make a nice micro ESC as well.

The leadless parts are REALLY hard to hand solder. :yes:

So, why is that one obsolete? Defect/not satisfied/etc? Just curious...

A couple of minor issues were found during the MM Pro beta test. Specifically, on 6S operation, we saw some issues with parts overheating on the switching BEC. We changed to a different BEC design.

How small can you go Patrick?

Funny you should mention that -- we were just talking about it.

The Mamba Pro was really designed as a sensored/sensorless controller for the masses -- inexpensive to build, very durable. But it has a big footprint.

We are talking about laying out a much much smaller version for the guys who are always asking for a smaller controller for competition.

It would be harder to build, and more expensive... But we could get rid of the heat sink, use an external cap, etc -- and make something really small for the racers.

What do you think?

Patrick, have you come up with an estimated street price for the MM pro?

It will cost about the same as the MM. But it has a sensor port, can run sensorless or sensored or hybrid mode. The MM Pro also has a switching BEC, and is good for operation up to 6S. So how do you like them apples?

Thanx!

I have 3 high Kv micro motors that needs a good esc as most I've used don't seem to work well. I'm running a Recoil with the 7500Kv version using the Tekin R1 (Sorry from bringing them up) and I'm looking for something really small to pair them with. I've noticed there are a lot of new MOSFETs available and some are very small. I like this one http://www.irf.com/product-info/data...rf6713spbf.pdf and it could be possible to make a 40A, that's all I need. Oh and a handheld programmer with an integrated CastleLink would be nice too.

Smaller footprints are always wanted with the high end users.

I think a smaller version would be great. More of a competition series for castle. Also good to see that it will cost about the same as the mamba. That is a great deal especially for the added features.

Won't be anytime real soon -- I'm working on the MMM 8S and 12S controllers now... But give me a couple months... :mdr:

I can wait. The motors will take a month or so to get done, but it could be longer if delays comes up.

I like apples. Tekin... not so much.

I am liking dem apples alot there Patrick. I especially like your produce prices!

Also looking forward to the HV Monsters and glad to hear word of them too.

No bashing Tekin or Novak in my forum please.. I like that there are alternatives that are USA manufacturers. Feel free to bash the Chinese and Taiwanese as much as you want... :lol:

Hobbywing sucks, they suck I tell you, suck, suck, suck, suck, suck!!!!:diablo:

That was for lutach mainly........:whistle:

:lol:

Now back to the CC show!

Any sensored motors coming out?

I thought Novak was made in China or do they just get the unassembled kits from Asia and assembles the ESCs here in the USA?

I was wondering the same, although it seems there is already a plethora on the market.

I'm cool with it. My lawyer actually said I can stop HW's product from being sold here in the USA when HW admitted they liked my ideas in a MSN messenger chat lol. I'm not a lawyer and I have no clue if it's true, but it's a good thing I save all my MSN chats I have lol. Now all the good ideas are stored in a safe place.

3 things that would make me buy a mamba pro, in adition to my RX8...
1. push button programing, simaler to the sphere or tekin, I can't stand the RX/TX programing...
2. a FUSE!!! have something simple that will blow before the whole esc goes, saves you $$, saves us $$ :yes:
3. user replaceable switch/servo leads:whistle: without voiding the warrenty

2: I think fuses have been discussed to death, and it was decided a fuse that blows fast enough to protect anything is impossible or highly impractical, else theyd be commonplace on all escs.

I think that all these new controllers hitting the market are great and gives us choices. It also creates some competitiona nd will hopefully keep everyone in check to prevent absurd prices. However as it has been mentioned many times, I would like to see a handheld programmer. Even if it cost $100, it's still cheaper and easier than carrying a laptop to the track, I think $50-75 would be a more marketable price point though.

Sounds great. Will the original MM be phased out when these are released?

Smaller footprint will be nice and external caps are no problem.

Sensored motors would be nice to offer....

Btw, I'm not big on apples, but I like those!!:lol:

You sure do know how to get us excited Patrick !!!

I agree. It would be nice to have some sort of catastrophic failure prevention, but how is a fuse to know if the current being pulled is "bad" (ESC failure) or simply a motor? After all, the currents are about the same.

Fuses are not likely to work here. Any fuse has internal resistance, say 1mΩ, that's really a tiny resistance, but under 100A current(pretty normal for RC app) this tiny resistance generates 10W heat!

So where is the 6-pin sensor port? no clue on your pic.

i dont care if that wasnt working properly...it is a magic piece of work!!
i reckon what you guys do is great....gawd knows what will happen when you guys make the first 1:1 scale car controller for electric 1:1 converts...i know i'll be first to buy one:lol::yipi::party:

shaun

probably on a seperate circuit board im guessing - i think that one is just the brains no fets on it either. (im not good at recognizing components though, probably does have fets and i just think they look different :p)

Might be on the other side of the PCB.

Any low KV motors to go with the Pro?

Yeah, the sensor connector is on the main FET board - -the picture is just of the "brain" board (we call it the "control" board.)

Patrick - love the 6S capability on the mamba pro. What about a waterproof ESC for our traxxas vehicles? Seems that more and more of their products are going that way and the Velineon is close to waterproof and they are saying it will be in thier catalog. That said you make much better ESC's and motors.

Pdelcast, I am very intrested in a 6s capable esc for mini's, I have been planning a mini e-revo and the best i can do is use a quark 33 amp at 5s. Like most wanting the 8s and 12 s mamba monsters, I am after efficiency, cool running and runtime maximized. I currently have a rc10 GT stadium truck converted to electric, running a quark 80 esc with a lehner 1200XL basic (1200kv), I am limited to 5s lipo because the quark's known hit and miss 6s capability. Suffice it to say, I would love to have an esc for my G E-gt that doesn't need a UBEC to operate. Not to mention there isn't a lot of room on the Mini E-revo for a external BEC
