RCX – Mamba Max has an official date

[party_wagon]

I'm looking for something for 1/10th scale electric truck. Throtle control is not an issue. What system is the way to go? I figure something that will put out power linear to a good 9x1 or 10x1 and maybe rev a little higher.

[tcolesen]

What will you be doing with it? If you'll only be doing street running, then the 7700 would work (but would be very fast!). For anything else, the 5700 is very capable. If the speed of the 5700 doesn't work for you, you could just gear up and it shouldn't have too much of a problem with that (in terms of heat).

[SpEEdyBL]

Has anyone tested the 5700 on 3s lipo vs the 4600 on the same pack? How is the heat? I was originally planning on getting the 4600 and I still am, but I'd like to know if the 5700 is really a good option also. Just in case... You know :)>:eek:

[chilledoutuk]

i also have the same interest in how useful a 5700 is on 3cell lipo as i really want a motor system that can be driven hard for long lipo powered runtimes.
I have a sneaking suspecion that while a 5700 on 3s lipo will be insanely fast the heat will build up in the motor to much on long lipo runs.

this is why i think the 4600 might be the better option for 3s lipo as the motor should be easier to keep cool whilst reving just over 51k rpm as oposed to 63krpm at 11.1v.

Here you go mate .

http://www.castlecreations.com/support/max_tuning_guide.html

Especially read the second page , i think the 5700 with 3s lipo will be what your after for speed runs :eek: .
I'll be ordering two 5700 packages from Jamie , now that iv'e also decided to run 2wd buggy ( just bought a XXX CR ) to keep my BJ4 WE company.

I'll be using a 2s for racing , but now will also be buying a 3s lipo for extended speed runs after reading the tuning guide :) :cool:

[SpEEdyBL]

Howevever, they say nothing about how hot it will get after a run, geared to go 60. I'm sure it is safe to run it, just like it's safe to run the lehner 5300 on 3s lipo, but a lot of us know that 3s lipo causes lehner to overheat pretty easily. For me, its my main concern because I mainly run 3s. I don't like motors that only have a few gearing options, nor do I like to cut runtimes because the motor is overheating.

[tcolesen]

These Mamba Max motors are supposed to be very efficient, possibly as much so as their more expensive counterparts. I guess we will just have to wait and see how they really do!

[USATorque55]

I'm very impressed by this system.

When I can get the money, I'll be buying a 7700 and dropping it into my XXX-4 or XXX-T.

Tim, whats the deal with amps on the motor? Is that released information or no?

[bigair78]

Won't that 7700 be the fastest thing on the market with 6 cells?

[tcolesen]

Won't that 7700 be the fastest thing on the market with 6 cells?

Besides a special-order Lehner motor (of 540 size), yes.

[Key]

Here's a close up. shape-wise seems very similar to the U-Force less the green and some minor trimming.

Looking forward to a 3s setup with 4700kv.

[ElectricThunder]

Cool.

Wonder if CC will make Berg receivers for car applications....:D That'd be neat!

[seth556]

They probaly will as they already have everything execpt for the right channels.

[flipmac]

Wow, the Mamba Max esc sounds great! with 100A continuous and 12 cells (14.4V), thats 1440W or almost 2HP. that's way more than the more expensive Sphere or GTB can dish out.

I was looking at MGM Compro 80 amp, Schulze U-Force 75 amp, Quark 65 amp Roadster, and Bk Warrior 7020/9020 for 1/10 application; all of them, except for the Warrior 7020, are more expensive, and all have lower amp rating (though Warrior 9020 is VERY CLOSE at 99 amps). The U-Force can also be used with brushed motors but it is almost $300! Only the Quark and Warriors can handle more cells. Then again, who would need more than 14V in a 1/10 car?

Considering one can buy a Mamba Max esc for as low as $135.15 (from Horizon for example), it is a very good deal especially that it is sensorless, easily programmable (with a mini USB port right on the esc), and should be very reliable since it is from CC (I love my Mamba Competition package).

I am very excited about this and will surely get one with a 5700 motor.

[tcolesen]

Don't forget that the Mamba Max can also do brushed motors! There's really no reason for the U-Force 75 anymore, the Mamba Max is at least as good!

[mindwreck]

Are they going to sell the motors individually?

[tcolesen]

The motors will be sold separately at Horizon:
http://www.horizonhobby.com/Search/Default.aspx?SearchTerm=mamba&CatId=

[party_wagon]

Does any one know if tower hobbies will carry them? They carry the original mambas, it would be nice to see these things available for around $150-175.

[tcolesen]

Tower Hobbies should carry them, since they carry all other Castle Creations items. Besides, it would undoubtedly lead to a profit for them to carry the Mamba Max.

[starluckrc]

The package is $249.99. CC enforces a 15% off minimum advertised pricing policy ($212.49). I wouldn't expect to see them any cheaper anytime soon. They will have no problem selling a ton at the current price.

[party_wagon]

Tower advertises at x amount of dollars, but they normal offer a coupon that will take off 15%. I bet you could see them for 185 or so.

[ElectricThunder]

That's my guess. Basically...in a nutshell, the mamba max systems will OWN most other systems on price alone (and performance will probably be nuts anyways)...:D :eek:

[seth556]

Wait so this thing can control my brushed motors and then when I buy a BL motor it can control that too?

[tcolesen]

Yes, it'll do better in brushed mode than probably all brushed ESCs out there (even though it's also brushless).

[seth556]

Sweet now I can just get the ESC then get some parts I need before BL then get the motor. So I'll be able to run my truck sooner.

[party_wagon]

How does it perform w/ the mini motors? Will it cure the problem of over heating in infernos?

[tcolesen]

The Mamba Max? It's not nearly meant for use in 1/18 and 1/16. It might not even fit.

[jchung]

I am thinking of getting one of these systems for my Tamiya Dark Impact. The only thing I will be doing is bashing, so I am looking at the 7700. What runtimes should I expect with a 6 cell 4200mah matched pack?

Also, I think I read in this thread someone running one in their DI. If so, may I please see your setup?

Thanks,
Jchung

[ffactory666]

So who is going to be running which combo and in what type of car.

I pre ordered the 5700kv from Jamie tonight for my off road buggies 2wd and 4wd :) .
In testing they compare the 5700 kv to a 8 -9 t modified motor and just call the 7700 kv scary fast :) , not to mention they couldn't get the system to thermal . Kept gearing it higher and higher , think they got the motor to around 220 and the esc to around 190 and it kept going.
On 2s lipo the 5700 got 40 mph and the 7700 got 50 mph.
With 3s lipo the 5700 got 60 mph.

If you don't have a slipper clutch yet, you'd be better off with the 5700. The 7700 would just be too much (IMO) for decent driving in the Dark Impact. But, if you're just doing straight lines and street type driving with good traction, the 7700 would also work well.

I'm one of the guys with a Dark Impact. My setup is stock except for adjustable blue aluminum turnbuckles and front universal joints. Because I got universals up front now, I was able to mod part of the steering to gain more steering, and the universals aren't even close to binding.

[party_wagon]

How smooth is the 7700 off the line? The more power the better, I have the smooth finger to control it. I am wondering if it is reasonable for 1/10th scale. Wheely pulling power at the end of a 200 ft. straight would just be plain fun though.

[tcolesen]

It's not about the smoothness of the motor (although higher quality does tend to make for less cogging) but the smoothness of the controller (less cogging) - the Mamba Max is a very smooth controller, hence the two year delay in releasing it!

[party_wagon]

So, you would trust the system out of a tight hairpin on a dusty dry track that you need the fast engine for the 200 ft. straights?

[enricopalazzo]

Im very interested in it, but until there are proper tests out there ie mamba max v novak 4.5, i will hold on to my money. How do i know it is heaps better then the Novak GTB? Simply saying it is scary fast is not good enough. Please someone do some tests!

[JakeE]

I don't think anyone has received theirs yet. I ordered a 5700 combo last Friday morning and emailed CC today inquiring if the order had shipped yet. I was told my order would ship within the next few weeks. :confused:

Which motor? As long as your batteries can handle it the 7700 will undoubtedly be faster. Also, the Mamba Max motors are more powerful (the rotors are larger) than the Novak motors. More power (as long as your batteries are good enough) gives you more speed.

Werd. Provided the batteries are good (which goes for any motor really), the mambas will blow the sensors off a Novak. From my experience with novak motors, they run relatively hot as well, and just don't seem as efficient as most other motors. From what I've read, the mamba motors are very efficient, which also means less heat, which in turn means more powah! :D

I orderd a 7700 friday, mailed cc monday asking since there was no money withdraw from my visa. Got an awnser Wensday saying they shipped out my stuff Monday and that my card will be charged this week(still haven't). So they ship out before the charge? Anyways I'll hope I get it soon. :)

[enricopalazzo]

I use maxamps lipos 6000mah 2sp

[tcolesen]

That should work. The Maxamps 2s 6000mah is also what I'll be using with my 5700 system.

[party_wagon]

what kind of run time do you get out of a 6k mah lipo w/ the 5700 or the 7700 system. Do the mamba maxs have a lipo cut off?

[ElectricThunder]

Do the mamba maxs have a lipo cut off?
Yes.

[tcolesen]

I never had a unit that functioned properly. But, my guess is that 15-20mins should be a good goal for the 5700, 15mins for the 7700, and 20mins for the 4600.

[SpEEdyBL]

Probably more like 30-40 minutes for the 4600. My 380c 9t got 15 minutes off 2500 mah of 3s lipo. On 2s lipo, it could probably go even longer.

[chilledoutuk]

what sort of juice does a 3s lipo have to be able to do with the 5700 ?

I have a 4100mah 15c constant 20c burst pack would that be ok ?

[TheSteve]

If the pack can really handle 15C without overheating it will be ok. A lot of Lipo packs seem to be overrated. I had good luck with the 5700Kv and a 3S Kokam 3200ma 20C pack. The Kokam would get quite warm with heavy usage(speed runs) using the 5700kv. On a small/medium outdoor asphalt track with the 4600Kv the battery was just fine.
If you want to rip up and down the street and your Lipo is good you'll be blown away by the 5700 with a 3S pack, if you have *any* weak parts in your car you'll find out very quickly.

[GTB_USER_ERIK]

Jamie?
Will the 5700 combo be a good choice for my MT2 conversion? here is the link I posted on this Forum last month - http://forums.radiocontrolzone.com/showthread.php?t=220805

[starluckrc]

I run a Feigao 540-7T in mine currently. The 5700 should work fine.

[scoob]

I pre-oredered a 4600 from you yesterday Jamie, can't wait to get it :) .

I need to figure out what 3s lipo I want next, I need to make 20 minute Pro-truck mains. I was thinking a 6000mah 3s pack. I'm going to have more horsepower than anyone and I'm the worst driver of the bunch. Should be fun :D .

[GTB_USER_ERIK]

Jamie; Thank you for the response :)

[party_wagon]

Has anyone looked into purchasing ball bearings that can handle a greater load? I realize that 1000 wats of power will put a lot of stress on those bearings while they whirl at 60k rpms, but I also know that there are systems that can handle a much greater load. Perhaps trying bearings from a trinity motor would be a good option.

[tcolesen]

It's not only the bearings but also the rotor. When the rotor spins faster there's a greater chance of it slipping on the shaft, which is when the rotor would need repairing/replacing. Do you think it's bad that the motors are limited to 65k RPM? Because it isn't necessary to make them spin so fast!

[glassdoctor]

Come on... what's wrong with a 150,000 rpm motor? When the rotor shatters it would be cool to see pieces explode through the can like a piston from a real drag car. :)

[party_wagon]

hey, there's plenty of people out there who will run 3slipo w/ one of the dynamite 9.6kv mini motors. You do the math. 11.1x9.6kv. Why can't the new mamba motors spool up to 105k rpm? Their mini motors get spooled up to around 80k+ rpm all the time. How come these new and bigger ones are slower?


























lol, I'm just joking around. The bigger spool probly would cause too much stress on the outer limits of the material on the outside of the rotor.

Optimaman ran I think a lehner 1515 5turn on 3s lipo. That's good for around 90k.:D

[tcolesen]

Yeah, but larger motors (bigger diameter rotors) will be more prone to breaking/slipping at higher RPMs than smaller motors due to less inertia and torque to move the rotor.

[GordonFreeman]

Please keep me up to date as to whether this ESC can take 4S and continuous 600W (1/8 racing, 4S, Fiegao 540 9C). I keep melting posts on my Mtroniks Truck.

[ElectricThunder]

I know. Just thought I'd throw that out there for party wagon to salivate over or something (and to display Optima's insanity). :D

[party_wagon]

If you gear the motor properly I would think it should be able to handle the load of an 1/8th scale. The engines produce nearly 2 h.p. I'm pretty sure that the 4700 system on 3s lipo could power a 1/8th scale buggy. Now, it would perform similar to an o.s. RG. However, it would still be fast on a tight track.

[GTB_USER_ERIK]

I did not relize that there was 4700 unit

[ElectricThunder]

I did not relize that there was 4700 unit
There's a 4600, 5700, and 7700. It's probably a typo.

[GTB_USER_ERIK]

Oh, ok thank you I read the information incorrectly :eek: and now that I have better information. My mt2 will scream with 11.1 Li-Po :D

[party_wagon]

I have not done any testing or seen any results personaly, but typicaly the higher in turns the more torque per rpms. Simply put. A 10 turn motor may put out 250 watts of power and provide 45k rpm at 7 volts. A 15 turn motor may put out 200 watts or power and 35k rpm at 7 volts. However, at 10 volts it may put out 300 watts of power at 45k rpm.

[tcolesen]

party_wagon, your more recent post is correct. The reason is because in the higher turn motors the resistance is higher, so the motor will require fewer amps.

About the Mamba Max working in a 1/8 buggy, it would but would overheat. I don't know what your experience is with 1/8 buggies, but even Feigao L can motors are very capable of overheating with the most optimal gearing, and they are longer and can put out more power than the Mamba Max motors without heating up as much.

[party_wagon]

The thing is though. The esc is designed to handle 100 amps of current. Running 40 amps to a motor at 11.1 volts should not push the controller to over heat. If the car is properly geared I realy think it should be able to power the buggy. What people don't realize is that the motor puts out around 2 horse power. Which means at most expect to see performance similar to an O.S. rg. However, an engine of this nature whirls at around 25k rpm. The mamba system will be whirling at around 50k rpm w/ a 3s lipo & the 4600 system. Now, this means that if you run a 15 tooth clutchbell w/ your o.s. rg you need to be running like a 7 tooth clutch bell. If it is geared properly it should not be an issue. I would not expect the car to be competetive in a nitro field on a very tight track. However, 30 m.p.h. is all that you could realy expect out of these cars. Remember that these systems have easily pushed 4 pound 1/10th scale cars to 50 m.p.h. I'm pretty sure that if you factor the wind resistance in there those motors are taking a huge load. As long as those motors stay spooled up and that fan is whirling I think it should be enough to keep the motors cool.

[ElectricThunder]

Just food for thought, but efficiency for the mamba motors is said to be between 84-88% peak. Of course, it (1/8 buggies) is still a great load for a 540s motor to take on. When the monster max comes out, I predict that system will EASILY propel a buggy for a long while without thermaling (especially if the motors are as efficient as CC says they are).

For reference. (http://www.rcgroups.com/forums/showthread.php?t=538309)

The controller is rated for 100amps, but there's no way that it can handle 100amps continuously without overheating.

Horsepower in nitro and electric applications are different. Horsepower in nitro is peak (only certain RPM), but for electric any amount of horsepower can be made as long as the batteries can provide it and the motor can handle the amount of current through its windings. But, if we're talking about heat, that's a different story. For the 4600 motor on 3s at 40amps and 85% efficiency, that's 67watts of heat to dissipate. But, that's only a mild current, especially for a 1/8 buggy. Try thinking more along the lines of 100amp spikes (assuming the batteries can take it) and 60amps on harder acceleration, with an average draw of about 25amps. Overall that's a lot of heat, and these numbers can come from just a 1/10 car, let alone a (twice as heavy) 1/8 buggy.

Now, the Mamba Max controller is a different story. It has yet to be tested in 1/8 buggies, it might hold up, or it might need a fan to hold up. But, there's no way that the 4600 motor on 3s Lipo will be nearly an adequate setup. Even with a fan on the motor you would be pushing your luck.

I dont know if this is a stupid question, but do the different motors (4600,5700,7700) have different peak efficiencies? I am guessing they do, but I don't know for sure.

Yeah, the peak efficiency for the 7700 is the lowest, the 4600 the highest.

WOW that is a big motor. do the endbell screws stick below the bottom of the chassis? Looks like a nice setup you have there with the shorty futaba servo and all. Let us know how it runs.

[TheSteve]

The motors are a full 540 size with the screw heads sticking out a little. If the motor is sitting in the right position(one of the screws facing straight down) it is possible a screw may hang below the chassis by a slight amount.

I may have sanded one a little....

[tcolesen]

I've found that the endbell screws (on both endbells) aren't the best things. In the Tamiya Dark Impact, there is a very limited space for the motor. It's so limited that the screws are completely capable of preventing the motor from being installed properly when the endbells are secured in certain sequences (where the screws are in relation to the mounting holes and where the wires exit).

[Rtsbasic]

Are you sure the rotor in them motors are a full 540 sized rotor? The CC site reads the part numbers as "CM36S XXXX brushless, sensorless motor", which hints at a 360/380 size rotor if other manufacture motor numbers are anything to go by.

I have to say Jamie has an excellent price on the ESC, does buying just the ESC include the link cable?

[seth556]

I'm pretty sure it does, or atleast I hope so because I'm just buying the ESC for now and then in about a month I'm buying a 5700kv motor.

The 36 in CM36S probably denotes diameter in mm. A 540 motor is a 36mm in diameter. It may not be denoting rotor size, but can size. I think CC also said they have 540 rotors in them anyways.

About the dimensions, whats the length of the motor? Castles site says 1.7 inches, but that's shorter than a regular 540.

[Micke_b]

Well, my thougths on the mamba max 7700 so far:

the good:
Rock solid, was driving hard for hour:s today, pushing it as hard as I could. It worked perfect. Also the programming is very good and easy(when using the usb cable). And its a very smoth system to drive. Didn't termal even with 100C at the esc, dont know the max??

the bad:
At 9.47:1 gearing at my tc4 it got really hot, both the esc and the motor was at 100C? After gering down to 10:1 I got it to be around 90C(just under 200F that is the max limit of the motor). Im not impressed by this. My old combo (feigao 380c-6t+uforce-75) geared for the same speed had a temp of 85C. I thougth I could gear the mamba system higher :confused:. And also I got the fealing the my old combo was a bit quicker at the same gearing/speed, not sure though, will test with the feigao motor tomorrow and compare.


Anyone know how to solve the heat problem? Or could I just gear upp desite the heat?


Anyway, Im still very happy with the system and would recomend it to anyone seeking a good brushless setup. My problems maybe can be solved with newer firmware? or some setting to the esc?

[SpEEdyBL]

You should definately be using the lowest timing setting. Otherwise there is something wrong.

Btw, since you already have your system, can you verify the length of the motor?

[tcolesen]

Another question, what batteries are you using? If you are using batteries with a certain limited power output, then there's no reason why the Mamba Max system with the 7700 motor would perform better than your 380C 6t.

[chilledoutuk]

tcolesen for many years i thought that the general opinion was that for light vehicles such as touring 380 sized motors were better.

obviously a feigoa motor is not a great example of what 380motors are capable of due to there reduced effciency in comparison to there german higher quality counterparts.

But i do aggree that for these systems having good cells is paramount as with these big rotors and windings there gona draw more current.

I would be very interested to see how the controller performs with the 6t 380c as on light cars with lipo the samller rotor might give a bit more punch.

I would suspect that on the other hand for trucks and other off road applications this motor would rock.

[TheSteve]

The 7700 really should have a lot more grunt(torque) then the 380 6 turn. If you're not seeing more power then I don't think your batteries can supply the amps required.

Unless changed from the default the U-Force also has a power limiter enabled. Schulze doesn't measure it as a percentage like Castle Creations does they list it in time. By default the fastest the U-Force will transition from slowest to fastest speed is 280ms, you can crank that down to 66ms, then you'll see more heat!

[tcolesen]

chilledoutuk, I guess what I meant to say was the power output (as TheSteve put it) rather than the type of performance one would see on a track where the lighter-weight rotor would allow for more "snappy" acceleration.

[Micke_b]

SpEEdyBL, Ive got the lowest timing setting. And the length of the can is 50mm, the diameter is 36mm


tcolesen, Im using Team Orion LiPo 4800 Platinum, I think they are good enougth. Bat temp today was around 40C. Or are they too weak?


Well, Ive installed some fans now, tomorrow I'll see what they will do for the temp, do anyone know a good heatsink that will fit the motor? diameter is 36mm?

heres a pic of the fans installed:

[TheSteve]

Keep in mind the contruction of the Mamba Max motors isn't the same as a Hacker(or clone) B50. The rotor is not as heavy or as large in diameter. The B50 motors always seemed a little laggy on 6 cells because of the heavy rotor and lack of efficiency with such a low voltage. The Max motors are optimized for car use so I would expect more acceleration with the Max motors versus an equivalent kv 380 sized motor.

[trd]

Micke_B the TO lipo pack works fine.

You're "burning rubber", my suggestion use foam tires.

[ElectricThunder]

Well, my thougths on the mamba max 7700 so far:

the good:
Rock solid, was driving hard for hour:s today, pushing it as hard as I could. It worked perfect. Also the programming is very good and easy(when using the usb cable). And its a very smoth system to drive. Didn't termal even with 100C at the esc, dont know the max??

the bad:
At 9.47:1 gearing at my tc4 it got really hot, both the esc and the motor was at 100C? After gering down to 10:1 I got it to be around 90C(just under 200F that is the max limit of the motor). Im not impressed by this. My old combo (feigao 380c-6t+uforce-75) geared for the same speed had a temp of 85C. I thougth I could gear the mamba system higher :confused:. And also I got the fealing the my old combo was a bit quicker at the same gearing/speed, not sure though, will test with the feigao motor tomorrow and compare.

Anyway, Im still very happy with the system and would recomend it to anyone seeking a good brushless setup. My problems maybe can be solved with newer firmware? or some setting to the esc?
Whoa, that's really hot for what's supposed to be a pretty efficient motor and a beastly ESC. Were those temps after a few hours of running, or after one single pack of running? If it was for a few hours, I could understand, but if it's after one pack, that's weird. Try a smaller pinion just for the heck of it, since it is a high Kv 540 size motor (amp hungry mutha and higher KV than the 380C 6t). What was the outside temp also?

[party_wagon]

The system is effecient because it normaly stays at a cool temp. Odds are if you ran it w/out your body the motor would stay very cool. The feigo may be a better quality unit, but the mamba was designed better. If the motor has some breathing room then it should stay very cool.

[jocktheglide165]

i sound stupid, but this is better than HV maxx correct? faster?

The Mamba Max is designed for 10th scale vehicles. Castle Creations will at some point be releasing the Mamba Monster Max for monster trucks and 8th scale buggy conversions. They haven't announced a timeframe for the Monster Max yet though.

Whats pinion count and spur gear were you using?

For the overheating part I would check these...

1. mesh- look for anything thats binding, make sure pinion and spur gear has some play.

2. timing, start power can not be above the recommended

As for you not seeing a snappier acceleration, switch to foams! :cool:

EDIT one more thing how long were you running? I noticed you typed "was drving HARD for HOURS" could be the reason for your high temps also.

oh ok thanks for info man...

[jchung]

tcolesen, thanks for the tips on the Dark Impact. I have several more questions though. So you only run universals in the front and it is not needed in the rear? And also, I want to stay with NiMh cells. What specs on the pack should I be looking at?

[ElectricThunder]

What specs on the pack should I be looking at?
High capacity matched packs will offer the best performance. I'd say GP4300s are probably some of the best cells out there, along with the IBs also. You may not even need matched if you're only racing club level and stuff anyways. :)

[Micke_b]

1. mech is good, everything spinns freely.

2. timing is lowest, startpower high, as recomended for high kv motors.

3. I was driving for 5mins, changing pack, 5mins and so on for like 5 hour:s took some smaller breaks. But the temp was high after the first run...

4. And you might be right about the tires, the asfalt was 48C if my irtempgun got it right and I was driving with 40C rubber tires. Hmm, now that I think of it I did lose the grip sometimes in the coners, but mybe just 3-4 times under all day. And a friend who tried my car yesterday called me later and told me he thougth that the tiers where overheating ass well and that I got "whelspinn" and that is was becaurse of that it didn't feal as "snappy" as it should.

It will be interesting to see how it work on a little colder day. Cooler tires/foams might solve all my problems.

Could this explane the high temps as well?

[ElectricThunder]

Usually warmer tires hook up easier....:D

[SpEEdyBL]

Maybe you should just see what happens if you gear it really high like 8:1. Just check the motor temps every few minutes.

[trd]

1. mech is good, everything spinns freely.

cool

2. timing is lowest, startpower high, as recomended for high kv motors.

ok try switching to a medium startpower

3. I was driving for 5mins, changing pack, 5mins and so on for like 5 hour:s took some smaller breaks. But the temp was high after the first run...

weren't you using the TO lipo pack?

Yes it could.... :cool:

[leomax001]

I noticed that as well, that the endbell screw was sticking out at the bottom of the chassi, but I have tilted the motor now so the screws wont be sanded off.

I'll be going to the track later today, I'll let you know how it runs and I'll allso be checking bat-temp, motor-temp and esc-temp.

....try this simple test:
remove the mamba motor and install the feigao 380C........
let's give us the result ;) ;)

Thanks ElectricThunder. I was under the impression that these brushless system must need matched packs to operate. I will only be running the buggy on a track, even racing is just for fun. I want to go brushless just for the power and no maintenance.

my TA05 -with little mamba-25 and feigao 380C-8t (4900kv)- on the track is fast as much as more "fashionable" gtb equipped 1/10 touring.... :D :D
now, I just waiting for my MAX (already ordered, esc only) to see how it will "scream" the feigao........ ;) ;)

[NIC]

Hi,

I´m Micke_b:s friend and I was with him at the track for an hour yesterday. There are a few things I can clarify from the test yesterday.
First the acceleration wich seemed not to be as fast compared to the C40 and Feigaos has two answers: The grip of the track. It had a really small amount of fine dust on it and the tires didn´t actually hook up as they should. I drove Micke_b:s car and felt the lack of grip on the track. Some corners were abit better, but out of the slowest corner the grip was not that great and that´s where you notice it the most. So actually the car didn´t find the grip for the power the motor put down. It could have been a little slippage also from the rear diff wich contributed to the "lack" of punch, though a little hard to tell really because of the track.
Second answer is the anticipation from this new system that the car would just take off like a bat out of h*ll and be lightyears faster than anything else. I can assure everyone that it IS more powerful then the C40 and Feigaos, I felt that.

For the battery not giving enough juice isn´t true. It can give the motor all the amps it wants.

For the high motor and batterytemps there are also some things here that contributes to that. First again is the track, it´s basically an on/off power track with three hard accelerations from low speeds and up to topspeed, then pretty hard braking from there. Yesterday was even worse cause the car pushed pretty much into the corners and you had to basically wait for the front tires to hook up then take the turn. This had to do with the dust on the track and a high track-tempeture wich led to abit of overheating of the front tires. This led to slow cornering speeds and therefore a low exitspeed wich the car had to accelerate from.
It will get better when the grip is higher, then you don´t have to slow down as much for the corners (less braking=less heat) and you will carry a higher cornering speed so the acceleration out of corners will not be that hard and from such a low speed.

Then for the motor itself. Overall I think a C40 has more coolingarea due to the built-in coolingfins then a smooth-can Mamba-max motor so it should disipate the heat better. As with all motors, they are only as powerful as they can disipate the heat.
In our case with our track and the conditions yesterday the system was really up to the test. Bare in mind we didn´t have any additional cooling for either the esc or motor. I know that the U-Force would have termalled in the same situation.
Perhaps to really extract all the power from the Mamba-system additional cooling and/or heatsinks is needed. Maybe the motor is "too powerful for itself". Not fair this early anyways to judge the motor and esc.

For the set-ups of the UF, we have always driven the esc at 66ms, not the factory-setting.

I will be at the track today for a few hours and help Micke_b with some set-ups and do more indept tests and comparisons.

I don't think there's a need for universals in the rear. The front needs them because of the steering, the rear would only need them if there was a lot more suspension travel.

[GTB_USER_ERIK]

NIC; thanks for the more in depth write-up, needed that. even I thought the Temps were too high.

[ElectricThunder]

Thanks ElectricThunder. I was under the impression that these brushless system must need matched packs to operate. I will only be running the buggy on a track, even racing is just for fun. I want to go brushless just for the power and no maintenance.
Nah, you don't need matched packs. You just need batteries that can supply the amp draw that the motor "wants". A matched pack will probably give you some more power though because in general, the voltages are higher and the pack is probably more consistent than a non-matched pack.

Matched or non-matched is your call. If you want some more power, then matched may be for you, but for the most part, if you're doing it just for fun, I wouldn't splurge on matched packs. You should still get some good cells though.

Either way, with a pack of GP4300s or IBs, you're going to have a lot of power on tap anyways...:D

[jchung]

Thanks for the helps guys, really appreciate it! I have a final question, what runtimes am I looking at with a pack of IB4200's for track running conditions with the Mamba Max 5700kv system. Just seeing how many packs I should get right now. :p

[jtracker]

Hey,
I ordered a mamba 5700 package the day they came out which was june 30th and still haven't received it and was just wondering if anyone else has received their 5700 package?? or if anyone knew when they would be shipping them out?? Thanks,

I don't think the 5700 combos have shipped yet. The only reports I've seen thus far have been from people who ordered the 7700 combo.

[crazyjr]

Mine hasn't arrived yet, i ordered mine on the first

[tcolesen]

CC doesn't even have the 5700 motors yet.

Runtime for IB4200 with the 5700 motor should be about 15mins. or so, depending on driving style.

[glassdoctor]

What???? How is starluckrc expecting them in stock 7/15 then?

So we STILL waiting on the MM?

Geeze... no offense, but I hope you're wrong, tc. :(

Btw I called to check prices direct form CC a few days ago and they didn't happen to mention the 5700 wasn't available... but I didn't ask specificly either.

[JakeE]

The Max has hit Tower (all have order pending status though). So much for a MAP of 15% off MSRP. :rolleyes:

Is it just me or is Tower beating Jamie on price? Amazing. For you guys in the US of course. Maybe Jamie can price-match? Guess Tower get a better price because they can order more at once.

I'd love to hear from someone on how the motors perform compared to Feigao's. Espically the 5700. Interested to see if it runs similar to a Feigao 540 6s, which so many people call sluggish because its a 540 sized rotor :rolleyes: I love mine though, fastest 6 cell motor for trucks I've ran.

Werd. Tower probably bought a HUGE amount or something. And to think though....205.99 MINUS whatever promos their running... :eek:

(with current promos, you'd pay 180.99 for a 4600 or 5700 system, and then add shipping...)

Hi,

It went better this time around. I cleaned the dust from the track with a leafblower and the grip returned. It wasn´t much dust but it makes a pretty big differens on our track, especially out of corners.
There are not many tracks you can keep full throttle for 4,5 seconds. Then you have 2 other straights were you have it nailed for 1,5 and 1,8 seconds. The lap record is 13.13 seconds.
Motor and esc temps were around 60C/140F when we left the track. The temps kept coming down all the time. Temp outside was 18-20C/65-68F and the track was around 28C/82F, we drove with Sorex 28R:s. The conditions was optimal heatwise for esc and motors this time with no direct sunlight and winds around 3-4m/s. Micke_b ran with a fan on both motor and esc.
I ran the Yokomo CGM with a C40-6S, Platinum Lipo, UF-75 and geared it 78/23 for a total of 7,97:1. We had the same speed and acceleration, I don´t know exactly what Micke_b:s ratio ended up beeing as he tested different ones. The motor seems to be able to pull some high ratios without loosing acceleration.

That sounds a lot better (140F). I'm sure the fans help out quite a bit. 140 isn't too bad though.

Other than the discount they are the same. Jamie is doing free shipping right now too.

[starluckrc]

I know customers see the great Tower discounts and think GREAT, I'll buy from there. They get around MAP with their coupons. The sad part is they put the little guy out of business, and there is no more support for the product from knowledgeable retailers that actually use the stuff. I remember trying to explain why I had to return a Kontronik controller to Tower. It was like I was speaking a foreign language. I can have sales and get better discounts through volume, but only if the demand is there to order the higher quantities. I am always doing all I can to bring prices down for the customer, so expect me to be very competitive. I'll price match as best I can. Also, I would expect it to be next month before Tower sees any product.

Always two sides to every story, and you're definitely right. (I've had to return things to tower...a few times... oh boy!) Your prices are the same as towers for the most part anyways. And their promos only last so long. And like you said, having a retailer KNOW what they're selling is always nice.

Will you be getting all three systems in the initial shipment or just the 7700?

I'm in Australia and order my brushless gear from Jamie .I could order from Tower and save a bit more , especialy since our dollar is only worth .73 of the US dollar.
Big deal if Tower is a bit cheaper , have you tried contacting them with any brushless info or help with a brushless set up you need or prob you are having with your brushless set up , tried returning anything that was faulty ;) .
Support the little man that actually knows what he is talking about and cares about his customers.

I know, thats why I brought my last ESC and couple of motors from him. When buying new, I wouldn't buy anywhere else.

Jamie, I just emailed you about adding a Castle Link to my order... hope that will be ok.

There system was supposed to be better than Novak's GTB and run cooler without the need for a fan, but it's obvious the fans have more to do with the lowered temp than any other factor.

I agree, Tower's price is only slightly cheaper after the discount plus their shipping, actually their shipping is expensive especially for international buyer like me, and its the normal air shipping. Jamie offered to refund me the shipping cost which his shopping system charge for International buyer, yes he offered me way before Tower even posted their mamba pre order. :)

[JakeE]

Jamie, I just emailed you about adding a Castle Link to my order... hope that will be ok.

I'm fairly certain the Mamba Max comes with the cable to connect to your PC. From the pictures I've seen it looks like the ESC has a mini USB port on the side versus the Castle Link which connects to the receiver plug on the Mamba 25.

[cart213]

Me, too. I know that I asked about Tower in the other thread, but it was mostly out of curiousity. The few bucks I might save aren't worth the lack of knowledgeable customer support. I'm debating whether to pick up a Mamba or a new chassis, but if I buy a Mamba, Jamie will get my money.

[Rtsbasic]

Personally I'm holding back on getting a Mamba for one of my cars for the min. I'd rather let everyone else do the inital testing and figure out what they're suitable for and how far you can push them, theres no big rush becuse quality controllers have been on the market for quite a while now at a price almost as cheap.

Micke_b and NIC- You were running a 7700 on a tight track right? Maybe that's why it was overheating. It could just have simply been too much motor for a tighter/twistier track. At partial throttle, the efficiency was in the hole compared to a 4600 or 5700 probably.

[tcolesen]

There is in fact a 6700 system. And how do I know :D?

Is this the first production 5700 that anyone has seen?

[Rtsbasic]

None the less, running a powerful motor on a small indoor track isn't uncommon, you'd have thought they'd have done some more expensive testing to ensure it doesn't heat up so much under these conditions. I don't see requiring the use of two fans to keep it from overheating as good engineering on their behalf.

[trd]

Micke_b did u try switching to a lower start up power? You should of started with the low or default settings. The only time you increase it is when your rc can't has difficulty running. Try it and that should eliminate the need of fans and bring down the temps. That's what I got from reading the manual online.

Tcolsen my beta lips are shut. Will giving advice be a violation per beta agreement? If it is I better erase this.

Hi,

How was the runtime on the Mamba, and how did it compare to your c406s?

We only drive 5 min heats and usually don´t check how much we can put back in the packs. You just know the Orion pack will be enough for a 5 min heat. We can look it up tomorrow if you like. If I remembered correctly I use around 2300mAh in one heat. We usually never charge the pack full as it takes so long. We just take it of the charger when it reaches 8,4V and starts to cut down on the charge current, around the 4200mAh mark. We also terminate the charge abit different each time.
We are so used to run 5min heats and push the cars and laptimes as much as we can so we rarely run longer then that. Sometimes we drive the last battery empty just because it´s the last one of the day and just fool around with the cars or show off for people around the track. There are always alot of people watching because of the rental go-cart track right beside the rc-track. We lower the tempo abit and don´t push the cars that hard so we don´t run the electrics to hot. I guess around 10-11 min and abit hard to compare the total runtime when the driving isn´t similar. We have different cars also.
Micke_b has the 4mm connectors on the Mamba motor and I have the 3,5mm. I will tell him to change to the 3,5mm so we can switch motors around.

There system was supposed to be better than Novak's GTB and run cooler without the need for a fan, but it's obvious the fans have more to do with the lowered temp than any other factor.

ALOT had to do with the wether. It was a completely different heat thoose 2 days. High pressure versus low pressure, and the air was hot with no wind blowing compared to cool with 3-4m/s continuos winds with windgusts that when going against them almost threw the cars off the track.

Micke_b did u try switching to a lower start up power? You should of started with the low or default settings. The only time you increase it is when your rc can't has difficulty running. Try it and that should eliminate the need of fans and bring down the temps. That's what I got from reading the manual online.

I will tell Micke_b to set the esc to its most limiting set-up, the #6 Start power as you said and maybe even the #4 setting, punch controll. I wonder though if the punch controll lowers the temp that much and if it has similar function as "time until full throttle" on the UF-75 ? The timing was set to the lowest anyway the second time we ran.

NIC

The punch control WILL affect acceleration, having no limit on the accleration will cause the car to lose traction (if you're using rubber, best if you use foams on this setting because foams tend to have more grip) and setting punch control to its max will make acceleration seem anemic but MORE controlable. So I don't think (not sure about this but this is what I get when I read the online manual) it'll affect temps.

[Rotary Rocket]

CC, or Starluck RC,

How well will this ESC work with Hacker "C" series motors?

Did any beta tester test this controller with said motor?

[Fenris]

Are the Mamba motor rotors 540 size? From what I have read up on the 380c motors they seem to be better than 540 size ones with the whole lower rotational mass of the smaller rotor seeming to spool up quicker. Wouldn't then a mamba controller and a 380c be a better combo, disregarding any extra efficiency of the Mamba motor?

[Rtsbasic]

Several people have confirmed it does have a 540 rotor size, as in a 36mm rotor. I too am curious to see how they perform, I would still think the smaller and lighter 380C's are better for a lot of 1/10 vehicles. A 540 rotor is a definate advantage in a heavier 1:10 truck though.

[Key]

Rotor Size is only one of several major performance factors in a brushless motor.

A few items to consider:

1) number of poles designed in a motor.

2 Segmented rotor vs. non

3 Fine tuning Throttle frequency (khz) via ESC. This depends on some variables ie. motor type and whether this parameter is accessible to adjust in your esc. (generally an option in high end comp. sensorless car escs).

In reference to #2 the segmented rotor is comprised of many small disks stacked on top of each other and this is the style that's supposed to lead to higher efficiency in partial throttle driving.

[jtracker]

GOOD NEWS!!! I got my mamba on Friday!!! YAH!! I raced with it on Sat. and got 5th in my class

[SpEEdyBL]

The mamba max rotors are actually slightly smaller than a 540 rotor that you would see in a feigao 540 motor, and more similar in size to a lehner basic rotor (though not exactly the same shape). I would expect the cm4600 to be similar to a lehner 4200 and the 5700 to be similar to lehner 5300.

So you're saying they're comparable to a slightly longer lehner basic rotor wise (but not quite an XL though correct...)?

[___rollin___]

Aren't the Lehner Basic series a 400 size rotor? The rotor is REALLY short too. I like it, spools up pretty darn quick. I would say from the pictures of the MM, that they're a tad longer.

[Rtsbasic]

I'm fairly sure the Lehner Basic's are a 540 size rotor, just a pretty short one, which is why its a higher power class than a 380-S Feigao.

[NIC]

Hi,

I tested the Feigao 380C-6T, Hacker C40-6S and Mamba 7700 on my UF-75 today and Micke drove the same brand new Feigao on his Mamba Max.
It´s past midnight here but I will report tomorrow how it all went with the tests.

One quick note is that the UF termalled with the Mamba 7700 at 4 min 12 seconds with 7,97:1, 201ms until full throttle/brake and super soft timing. I have a small Atomic 5v fan on the esc wich is wired directly from the Orion Lipo. Speed was really good though up to that point.

NIC

[Rtsbasic]

If the MM is significantly stronger than a UF75 it must be excellent value for money. Can't wait to read a full report on how they compared, and how the motors compared, when you get a sec to write it down :)

[burnineyes]

got the 7700 last week and i am very pleased. we have one of those police radars up the street that flashes your speed on a big screen, in my TC3 it showed 57mph first run, 58 second, and then a 56mph when i had some traction problems on the last run. i believe the last run could have been faster but it was almost completely sideways when it passed the radar gun! that was with 7 unmatched 3300 cells, and a 7.2 overall gear ratio. looking for mid 60s with some sticky tires and another cell.

That's freaky fast. How were the temps of both motor, ESC, and batts?

[___rollin___]

wow, high 50's with 7 cells! 8 cells should be pretty nutso. Report back with the 8th cell runs if you could. As ET said, how were the temps?

[burnineyes]

the motor was the only part i checked, because all i have is a M.I.P. temp guage stuck in the heatsink. it reached no more than 140F. i will check tomorrow with it on the esc, but it felt cooler to the touch than the motor. the batteries were pretty hot though. i could feel the power cutting out on later pulls at my house. not sure how much longer they can take this abuse. :eek:

[NIC]

Hi,

Track temp was 30C/86F and outside temp was 19C/66F. 50/50 clouds/sunny. We ran 5min at maximum pace pushing really hard out of slow corners.

Micke had this set-up on the Mamba Max esc:

#4 Punch Controll: 20%
#6 Start Power: Low
#7 Cut of voltage: 6,4V
#8 Timing: Lowest

Car: TC4
Motor: Mamba 7700
Esc: Mamba Max
Battery: Orion Platinum Lipo
Gearing: 8,57:1
Body: Protoform Alfa
Tires: Sorex 28R
Others: 5v fan on both esc and motor

Temps were:
Motor: 73C/163F
Esc: 55C/131F
Bat: 42C/108F

With a Feigao 380C-6T with the same gearing and esc-setup, just a change of motor:

Motor: 65C/149F
Esc: 45C/113F
Bat: 40C/104F

My setup:

Car: Yokomo CGM
Motor: Hacker C40-6S
Esc: U-force 75
Bat: Orion Platinum Lipo
Gearing: 7,97:1
Body: Protoform Mazda 6
Tires: Sorex 28R
Others: 5v fan on esc, no fan on motor.

Esc setup:
Time until full throttle and brake: 201ms, I wanted to save the drivetrain abit and try to mimic the 20% punch controll on the Mamba esc.
Super soft timing
Voltage cut-off: 6,4V
Intial throttle: 0%

Temps were:
Motor: 70C/158F
Esc: 57C/135F
Bat: 44C/111F

With the Mamba 7700 and same setup in my car the UF-75 cut-off at 4 min and 12 seconds. Hardly any surprice really as I drove with taller gearing then Micke and the UF doesn´t have as good specs as the Mamba esc. But pretty big differens between the C40 and Mamba 7700, 57C on the esc for the C40 compared to shut down at just above 4 min. When geared hard the Mamba pulls big amps, no surprice really. Motor ran good and very smooth until the esc shut down. Topspeed was really good offcourse.

Temps (meassured directly after shut down):
Motor: 70C/158F, no fan on the motor
Esc: - didn´t bother to check
Bat: 43C/109F

The temps would be higher on the motor and bat if the esc would have last the hole 5 min.

The cars was pretty much dead even on the long straight with 8,57:1 for the Mamba in the TC4 and 7,97:1 for the C40-6S in the Yokomo. You can slipstream pretty much at these speeds. Acceleration was also very even.

NIC

[Micke_b]

At last my internet conection is back up....

As for the high temp of the mamba max esc/motor in my first runs, I actually dont know why it was so hot. And it seemed that the higher we geard it(more speed) the cooler it went(tryed 10:1 -> 7.86:1). And I don't think the fan on the motor does to much cause the motorn don't have any fins. In the future I'll try and mount a heat sink as well on the motor and then it should be really cool.


So the the awnser to the heat issue(according to me) is that the 7700 motor need some resistance to run cool. Could anyone explane this?


And about the "snappyness" 540 vs 380, feigao 380-6t vs CM36-7700. I now know that the 7700 is indeed "snappier". At the same gearing the 7700 is clearly faster/more powerfull.


Well as the system works now Im very happt with it. It works perfect and runs cool enougth. And it have plenty of power. But NIC and I alreay started to dream about 3 cells LiPo + the 5700/4600, now THAT would be fast, dont know if my tc4 will hold up to it thougth. But 3 cells wont be an option for earlyest next summer, if at all.


Next time Im on the track I'll try and run without fans vs with fans and check the temps again.

[TheSteve]

Here is a picture of my Mamba Max install in a Losi Jrxs. The setup is a 4600kv motor with Kokam 3200ma 20C 3S pack. The pack has been redone in black shrink and I machined a custom battery door out of carbon fiber so the pack will fit.

Hey Steve, it's good to see you got yours! I see you took the wire-shortening route, I'll have to try that soon. Can you comment on how that went?

[TheSteve]

Piece of cake - didn't touch the power wires on the controller pcb. Figured out the length I wanted and soldered on the deans for power. Then I removed the motor plugs, cut the wires to the length I wanted and soldered them back on and put on some nice black shrink.

Does anybody have a good idea where i should start, gearing wise for a AE t3 with masher 2000' with a stock psur gear, 87 tooth i think

[glassdoctor]

I ordered on 7/3. Maybe it's on the way.

Which motor? I would start around 20T for 5700 but I haven't run one yet. Maybe a beta tester can give a better suggestion.

Sorry, its a 5700 system. It will be run on 6cell 4000mah 4K batteries from max amps, i got other batteries but not sure if they can do the job.

I got Email confirmation when it was mailed

[ElectricThunder]

crazyjr- Try a lower pinion than 20 if you're running M2ks. Work your way up from roughly a 15 tooth. Although the 5700 can probably handle 20 just fine, the tires are something to certainly consider pertaining to load. :eek:

[burnineyes]

i could only get a 17 or 18 to fit on my t3, with the 87 tooth spur. the screws in the sides of the motor can will not allow much movement at all in the t3. this is my only complaint so far though.

ran the seven 3300 cells until they dumped today, about 15 to 20 full speed passes. temps were as follows:
motor-145F
ESC-140F
BATT-155F
these temps were not actually reached untl a minute after the run, with the high speed airflow they were all between 120-130F immediately upon stopping. never really checked temps of my batts before, whats a normal operating range for ni-mh cells?

[party_wagon]

[GTB_USER_ERIK]

Jamie: I just purchased a 5700 combo from you.
when can I expect delivery??

[billy gunn]

My initial reactions, I have the 7700kv setup and it is in a TA05...

It is a smooth setup, with good batteries there is no cogging and response at all speeds are good. Someone who drives a GTB system, felt the system was smooth and had excellent power all the way through the RPM range.

With some old, hammered, worn out IB3600 packs, a confirmed 41MPH using a GPS, the setup I used was stock from the factory, but put the timing on "low" and put a little drag brake in. Temps after burning off two packs run were: outside 95F, motor 170F, and speedo was 220+F, a little too hot, but it did not thermal.

Throwing a Thunder Power 8000mah li-po pack into it I was able to reach 48-50MPH (no GPS that day) I dropped the gearing, and put the timing on "lowest". Temps after running down the pack were: ouside 95F, motor 165F, and ESC 178F.

It is still running a little hot, so I have added a fan and dropped the gearing a little more. I think the major problem is that I am running on a parking lot were the asphalt temps were approaching 140F, so it's hard to keep everything cool.

[Muck]

Has anybody figured out a good way to mount a fan on the MM esc. Pic's would be nice if you have them.

Wasn't trying to sound disappointed, mine is very very powerful, and is extemely smooth for sensorless. The temps I posted I don't feel were all that high seeing as it was close to 100F outside, and the asphalt I was running on was close to 140F both days, it was hot enough you could not touch the asphalt for more than a second.

Just for comparison, I was running with a friend who has a GTB 5.5 in his Corally, his speedo and motor were both around 200F when we were done, which is quite a bit hotter than mine was the second day on the Lipo pack. And yes, we were geared pretty close to the same.

Nevermind then.

Anyone running a 5700 at all? I'd be interested to see how those temps are (and even the 4600).

[glassdoctor]

I was gettting a 5700 but I messed up the order process. Now I'm getting a 7700 cause that's what is available. I hope that wasn't a mistake. I think maybe the 5700 will be the best one all around.

I race 1/10 offroad... maybe the 7700 will be ok for 4wd. Too much speed is no problem... but too much heat is.

how's the speed compared to the gtb 5.5?

[tcolesen]

My 5700 runs well, I just picked a random pinion gear (20t) to go with my 81t spur gear, and it worked well enough that I haven't even tried different gearing options yet! The controller runs about 145-160, determined by if the body is on or not (there is no cooling air with the body on). The motor sort of has a fan over it, due to the VERY limited cooling with the body on, and it gets to about 150-160 deg. The battery (Maxamps 2s 6000mah) runs about 100 deg. All are well within their limits, so I'm happy (5700) :).

[billy gunn]

how's the speed compared to the gtb 5.5?
Top speed is pretty close geared about the same ratio, acceleration was better. The Mamba seemed to have better power all the way to top speed. If I were to gear up and gear for the same temps that the 5.5 was running, the 7700 would kill it in top speed.

Does the MM controller have the option of shutting off the bec so that a ubec or receiver pack can be used instead? For instance, if you want to use 4s lipo?

heat won't be an issue, the problem will be that the systems computers need x amount of voltage to properly operate. If theres enough voltage going to the system then it should work. No, it won't over heat from using too few cells.

Hmm, maybe I was unclear... that was 2 diffrent questions.

1. will it work on 5 cells? I mean The cutoff have a 5volt option(5cells=6volts), and I can set the custon cutoff to 4 volts if Id like. So why wouldnt it work with 5 cells??

2. How hot will it get bofore it shuts down cause of the heat?, with what ever setup the push it hard enougth to overheat.... Im had mine up in 100C and still running ....

Dont tell castle but I did try my 4600 in my G-maxx. It worked and didnt thermal but it wasnt what I had hoped im back with the 8xl now. The 4600 and a 4s lipo is headed for my Tc3 there is a new guy with a n4tec who thinks its the fastest thing ever.

[mp3ranger]

I just got my free system for doing the beta testing.

CC's site suggests their 5600kv/540 motor works best with 3s. Since it looks to be a little on the hot side wouldn't 4700kv be a better choice when running on 11.1v?

5600 = 62160 rpm
Vs.
4700 = 52170 rpm

[TheSteve]

Guess it depends on how fast you really want to go. The 4600 is very impressive on a good 3S LiPo pack, the 5700 is even better. If you want to drive a medium sized track the 4600 would probably be better, you'd need a large track to get the real potential of the 5700. Driving around and hardly touching the throttle because the car is way too fast is not the best way to get around the track - you'll be slower then those with the proper motor and things will run hotter.

I like (and recommend!) the 4600 with 3S.

If you want to do 60 to 70 MPH everytime you squeeze the trigger grab the 5700 though - better have the batteries and car to back up that power though!

Thx TheSteve this is some valuable info :)

Another Q.

How would u compare speed and torque of a CC 4600 540 size motor versus a 2-pole kontronik twist 4700kv 400 size on 3s, for example?

[TheSteve]

I haven't used a Kontronik twist motor myself, the closest I've used would be a Hacker C40 12 turn(3500kv) I think top speed will be about the same as long as they aren't over geared, you will still have more low end grunt with the CC 4600 though. I've seen no signs of the slightly larger rotor spooling up slower. This may also be related to the processor Castle is using in the Max, its quite powerful and runs at a good speed, so it can process code and react very fast. The controller always feels very responsive.

[Nabors]

Played around with my 4600 in my RC10T4 today. With an old and tired 6cell 3300gp pack it went 31mph with 15+min run time. Put a 8 cell IB 3800 pack in and got 42mph and about the same run time. Both of these speeds are dead on what the math says it should run.

Reason i got the 7700 is because i already have basic 4200 and feigao 12s which is around 2900+ kv, i want more variety of motors,if the 7700 doesnt work well with emaxx, i still have other 1/10s i can dump it in. Will try the mamba max with the other 2 motors i have now, when i get my hand on the max that is. if i like it very much, i'll be selling some of my rc stuffs to fund the second set of mamba max with 5700.

Jamie: is my order on the way already??? :) :D :p

glassdoctor: nope i'll be running both 1st and second gear. I wanna test whether this is a strong system.

[glassdoctor]

I wanna test whether this is a strong system.

Just so you understand that the 7700 really isn't well suited for an emaxx, and that an emaxx really is not the barometer that shows whether or not it's a strong system.

It's like using a Corvette to pull a trailer. ;)

But it's all good... and it will work, of course. Gearing it low will help out a lot... that's why I mentioned running in first. I have done that with my emaxx.

Let us know how it works.

I'm going to slap a Mamba Max in a car that it's not designed for as well... so I'm not trying to be critical. Just help. I'll report what happens in my testing too.

[rca]

Yup I agree with you and I'm not trying to be critical at all :) My main intention is to have decent speed and torque that is equal or slightly better than any 14 cells emaxx running on stock motors at 30+mph, at just 6 cells. If it runs well, I won't need to purchase and carry so many batteries, my emaxx will run much lighter and less stress on the drive train, lesser chance of breakage during high jumps.for all out power and speed, i'll wait for the monster max :)

Well its just like installing the corvette's engine into a bus, geared properly u might have decent power/speed on the bus, if it doesn't work, well I could always install the engine back into the corvette right :) just curious, what car u intend to test your mamba max?

[glassdoctor]

777 :D
a.k.a. speedo killer
It's ready to slay a snake.... :eek:

[Combatcm]

I want to get something straight, as long as it has enough cells to run efficiently, there is ALWAYS a sweet stop for gearing? Whether it's a 5lb truck, 8lb truck or 18lb truck you can always get it geared without thermal problems. Even though the truck might go 8mph?

[glassdoctor]

Well I don't think that's what we want to do though. ;)

[bigair78]

Now I just need to know a good starting point for a factory team tc4?

[bigair78]

Here is another.

Too bad you said that...LOOK WHAT I FOUND ON THE HIGHWAY on 7/28/2006

[bxpitbull]

And here's another shot

Deh Deh Deh thats re-tuh-deeeddddd!!!!

[Chachi_RC]

I just have to say off topic, but how friggin' funny that you found a 'Vette pulling a trailer after that comment!! LOL!!!

[glassdoctor]

Ok, ok.... I was thinking of a pulling boat or a bigger trailer than that. I have a 4000lb boat so that's what I'm thining. That hardly counts as a trailer. Hee he he funny.

State Patrol should pull that guy over and give him a citation for stupidity... and for cruel and unusual punshiment to a legendary automobile. :D

At least it's not a Z06... one of the greatest cars ever made, killer of all less-than-$1,000,000 supercars.

[Chachi_RC]

No, I agree as well, but you have to give credit for seeing and picturing that! I am getting ready to build a GorillaMaxx G2R Revo Conversion, and I am thinking from what I hear, the Monster Maxx would be the way to go with it. I would like to pull a wheelie when needed, but want the good top end too. This messes with the idea of a single speed lock out, but as stated, I want the bottom end torque. Best of both worlds I guess!

[WIA041212]

I am fairly new to the RC world and I wanted to upgrade my Dark Impact a bit. I was looking at the 5700, but what else am I going to have to get to make it work. Any info will help.

[glassdoctor]

You don't have to have anything special... just the 5700 system.

As for the DI... it may have some weak link in the drivetrain that will need upgraded, but I'm not aware of any. I think they have been pretty tough.

[WIA041212]

Thats good news. I was expecting to have to upgrade everything. What would be a good drivetrain upgrade?

[tcolesen]

You really only need front universals for the DI, but you need those with any brushed motor as well. It would also help A LOT to get the slipper clutch.

[GTB_USER_ERIK]

I got mine today.
Thanks Jamie :D

[Chachi_RC]

Any word on release of the Monster Max system?
