Nice controller, thing is though that the Mamba Max is actually cheaper (only 130$ for ESC Alone) and everyone has heard of it, why should people buy this controller which is more expensive and personally never heard of the brand?
(Not flaming you or anything just want to know why this is better than Mamba Max) :wave:

[tcolesen]

It does appear to have similar specs to the Mamba Max, with 3s Lipo or 12 cells maximum with the BEC enabled, and 4s Lipo or 16 cells with the BEC disabled. I too am curious to hear the advantage of this ESC over other controllers like the Mamba Max.

This picture looks interesting...

especially since the MAX is a VERY well known esc, excellent customer service AND its cheaper :P

What the crap?!

Jackson_f- Could we have more information on the picture that splode posted please? :eek:

[Demon-TC3]

looks intresting but i dont see the advantage of twin brushless, people find it hard enough supplying a single brushless motor with enough juice without goin to Lipo :P

Still progress is Good, please explain :wave:

But two motors is ungodly powerful....:D (Since when is too much power a bad thing?;))

[splode]

I was actually hinting at the fact that both motors are running off of the same controller.

Edit:
I should have included the caption.

Since some conversions drivetraines barey withstand use with a single brushless motor :P

Still its not going to give much more power since a single Feaigao 9XL motor on 12 cells geared well will give you allot of torque...more cells = more torque. more motors = Much more drain, more drain means the torque will last allot less...

Still its nice to know the speedo can handle 2 motors...(well apparently it can :P)

I was kinda being sarcastic, but ok!:D

I'm curious as to how it runs and if the ESC gets "confused". Looks "different", that's for sure!

Yeah, that's what I was shocked at (the two motors off of one controller). That's quite an accomplishment if they figured out how to do that. May not be useful, but hey, it's still neat.

[rccardude04]

Looks like RETAIL is $159. That'd put sale price probably around 120 bucks?
How much is the mamba max esc?

i think that the controller will not be confused becouse the two motors will be running at the same rpm.

[ElectricThunder]

i think that the controller will not be confused becouse the two motors will be running at the same rpm.
It's a sensorless ESC though. It determines rotor position by back EMF or something like that (it's late...forgive me..:D). If the motors have slight variances between one another (let's face it, no two motors will be exact in this hobby), then the EMF generated for the ESC to "read" may be somewhat different from the other motor, and thus the ESC will be getting two different readings from what it sees as "one source". I don't think it necessarily has anything to do with RPM, but more with resistance of the coils and other variables.

That's why I'm confused as to why they have that picture there. :eek:

Maybe they got some kick arse software going on or dual chips on there or something. :confused:

[Stuart B]

I won't be replacing my mamba for one but I love the way the motor wires atach to the board. Nice gold banana straight to the board...sweet.

[Demon-TC3]

yea i too like the bannana plugs...although if one of those came out it could short out and cause...a bit of a problem.

AS For the Mamba Max, it retails (esc alone) for about $130.00...so even if hte Unit was being sold for 120 sale price i would still pay the extra $10 and get something i am sure of.

that said i am looking for a new brushless esc for a 1/8 conversion in the next few months, so if these go for about $100.00 then i would say it would be worth it.

[starluckrc]

FYI, Mamba retails at $159.99. The minimum advertised price is 15% off of retail.

[Demon-TC3]

hmm seems like ur right, sorry bout that, Still, this new thing has to be a hell of allot cheaper than the MM to be worth buying!

[kufman]

Where is the case??? USB Programming?? Were is the nearest servicing center??

[Demon-TC3]

the heatshrink IS the case :P...not too worried about that personally, service centre seems to be non existant and the USB lead takes the form of a button...

In other words this thing is a basic ESC with a very optimistic company!

As i say, it is worth $100.00...maybe a little more but compared to the MM i dont think i would take the risk.

We use a unique trigger programming with read back feature.

For service, will need a trip to Hong Kong.

I will post a simple rotor aligning method for 2 motors later in this few days
for you guys reference.

I figured that's where this was going.

[Stuart B]

some electric planes have 2 motors of one controller, and they aren't bolted/geared together to ensure they are timed together, and they work. I guess with 2 motors fixed at the same timing should work even better,

Dear All,

Thank you for interested on one of our Test Bed - the 1/8th scale Monster Truck. The prime purpose of building this Monster Truck is to ‘torture’ ESCs by giving them far from ideal conditions, i.e. higher than rated current draw, bad motor timing & etc. By having such a Test Bed, we can collect information and modified the ESC as required. We had an intention to convert the Truck back to a single BLM configuration after all the tests have been done. However, this twin BLM setup did draw a lot of attention, triggered discussions and provided a lot of fun therefore we decided to keep it like this.

As promised, I would like to share with you the procedures we use to align the rotors for 2 BLMs that drive a common spur gear. It is easy and no secret. However, please take note that I am not here to encourage you to use this setup as we all know that the efficiency is relatively low.

To set up for twin BLMs operations:

1. Make 3 sets of Y-lead out of heavy gauge wire.
2. Insert the pinion gears onto the motors shaft. Do not tighten the set screws at this stage, the pinion gears have to be free to rotate on the motors shaft.
3. Mount the motors onto the model.
4. Connect the Y-leads to the motors and ESC. Please take note of the connection in accordance to the colour of the wires.
5. Run the 2 motors together at low to medium speed for a couple of seconds. The spur gear should not turn as the pinion gears are free to rotate on the motors shaft.
6. Disconnect the battery.
7. Apply some good quality thread-lock to the set screws and tighten the set screws to the pinion gears. Be extremely careful not to turn the pinion gears, spur gear or the motors shaft as they must remain at the position where they stopped.
8. Use an oscilloscope to confirm that the voltage generated by the 2 motors is in phase (as shown in the photo). The ESC will now treat the 2 motors (or even more than 2 in other applications) in sync as a single unit.
9. A less accurate method is to use a Multimeter (set to AC current) to check the phase-phase current between the 2 motors. Disconnect 1 set of Y-lead and connect the Multimeter probes to the original lead of the 2 motors. The current measured should be in the order of 0.1mA if the spur gear is turned by hand.
10. You must use step 8 or 9 to confirm your setup. The ESC can still run the 2 motors even they are way out of phase. In such case, large amount of current will flow between the 2 motors and if you turn the spur gear by hand (with all 3 Y-leads connected to the motors but the ESC disconnected), you will feel a braking effect or resistance (The motors are now acting as generator and motor in turn).
11. Other considerations:
(i) The backlash of the gear train may affect the phase angle of the 2 motors.
(ii) The close proximity of the motors may cause cross coupling by stray magnetic Flux.

I hope the information could help.

What I would recomend for any comapny coming out with a new BL ESC, is to have it handle at least 6S Lipos or more.

[Demon-TC3]

im not so bothered about the voltage capability, it is more than enough for the Majority of people, what im not so fond of though is the price, its the same price as a MM esc and yet doesnt have as good a customer service, noones ever heard of the brand, AND noon has any idea what the quality is like (well since its wrapped in heatshrink you think thats an indication?)

For that price who could possibly justify buying that over the MM?


Oh yea and one last thing, cant beleive i forgot this,the Mamba has a USB lead which allows you to set it up and upgrade the esc...

Why does it cost so much???? :confused:

[Marv829]

For that price who could possibly justify buying that over the MM?

The Mamba Max ESC leap frogged over everything else to become the "King Of The Mountain" for 1/10th scale sensor less brushless almost immediately after it was released. I predict it will stay there for many months if not years. Its features and price will be hard to beat.

[Demon-TC3]

yea i agree, althogh, i would justify buying one of those if the price was right...woulkd you agree that $100 is suitable baring in mind what i said about is earlier?

[serum]

first thing i thought when looking at that dual motor pic;

Why!? a single motor can take all the energy the cells can deliver. Leave alone two of them...

running two motors on one esc, without interfering with the EMF feedback is quite simple; you can align the motors by putting a small DC on two of the three wires. do this with both motor, and they will Align. Since the motors are mechanically connected thru the spur, their timing won't change. Unless you use two different pinions..

[Demon-TC3]

thing is though i still dont see how it would work, if the motors are not identical one will want to push harder than the other..just because they are aligned wouldnt mean it would stay that way would it?

Even if it worked well, would it matter? people find it hard supplying one motor with juice let alone 2...
