The 5700 system should be a little bit faster then the 4.5 Novak system but has much more torque. If you're racing the Mamba is defently not race legal. According to Castle the 5700 is supposed to perform like a 9t brushed motor but thats just on 6-cells, remember this can go up to 12 cells or a 3 cell lipo battery for insane uncontrolable runs. I also heard this guy broke a custom titanium dogbone of his t4 with a half charged lipo pack. Anyways I'm expecting great things.

I don't think it could keep up if it is only going to go like a 9 turn.

Don't forget the Mamba is designed to be over / under geared to control your top speed without effecting the motor or esc .
In testing they tried to get the system to shut down by gearing it higher and higher and the system kept on going with a crap load of torque to boot.
So with the Mamba 5700kv you just gear alot higher and it will out run the 4.5 no prob without fear of thermaling, especially on 3s lipo's.

Try undergearing your sensored system or overgearing it , the esc will overheat if you overgear and the motor will over heat if you under gear it.
I sold my two Novak systems ( 5800 and 6.5 ) this summer in Australia as when i tried gearing higher , especially in hot weather the systems would thermal .

I'm now waiting on my Mamba Max 5700 kv systems ( bought two ) to arrive in Australia . One will go in my xxx cr buggy running a 2s 6000mah lipo pack at club days , and the other will go into my 1/10 pan car running 3 s 8000mah lipo saddle pack for bashing against 1/8 nitro on roaders and speed runs ( should easily reach 110kmh and over ).

I'll be doing a review in the Australian forum when they arrive

Yeah I can see your point, it's just that it a very new system and I've never seen one run. Novak have been out for a while and I have seen alot of them run and they usually finish around the top in most of the races up here in QLD and Australia. And I haven't had my system thermal as of yet so the thermalling issue doesn't worry me. Where in Aus do you usually race??

I havn't raced off road yet , will be racing once i get my Mambas at Knox down here in Melbourne, only on club days though as the Mamba is not legal fsanctioned racing.The reason it's not legal is because the Mamba is running a 540 shaft compared to the smaller shafts on the Novak/ Lrp's.
Thus another reason that it has alot more torque and being able to overgear the motor.
My novaks were in my bashing cars , was gearing higher for speed runs in a B3 and a Stampede using 8000mah lipo with low voltage cut off and was having heat issues ,i was runnig up to 45mins on the lipo and got fed up and sold them.
The Novaks' and LRP's are designed for racing so they were never designed to run big lipo packs with mega runtime 40 - 60 mins straight.

Now the Mamba is more of a do it all system thus the reason iv'e gone for it over the LRP which i was going to get after selling my Novak's.
I'll under gear it for 2wd off road racing using 2s lipo or 6 cells, then over gear it and run 3s lipos or up to 12 cells for speed runs and bashing and around 45 mins runtime without thermaling on a 8000 mah lipo.

As they say different strokes for different folks

Now don't forget that all this is going by the Mamba's specs and reports from people testing the system so once i receive mine i'll report on my findings, which going by my past experience with CC should be awesome.

Right here , http://www.starluckrc.com/catalog/pr...9a72423857c1cc .

Jamie's service is top class and he knows what he is talking about when it comes to brushless systems

Well if it does become legal and is extremely fast when setup for racing then I will definitely consider one. Hopefully I can talk jmack111 into getting one so I can see it go.

Well i'm hopeing it will become legal but the rotor being 540 size is a big issue with the ROAR rules so i can't see it hapening.

On another note , i'll probably be buying a LRP 4 star or Novak 4.5 to race in 1/12 pan car on 4 cells if i decide to run 1/12 . The Mamba can't go down to running only 4 cells and i know th Novak / Lrp has no prob running 4 cells in a 1/12 pan car.

I would really REALLY !! like to see some fair dyno test results on these motors and the new novaks 3.5
Just to see them in comparison and theire difference in torq / rpm .....



anyone with the ability and hardware please post some data !!!

sensor to sensorless is a no brainer. the 4600 has already been smoking the novak in the water and on land for the last 3 months just no one knew that we were running them.TO DUHH: as far as comparison the is none period. the 4.5 is clean but they all have max of 65,000 rpm and that's that. anyone at rocks last month will tell you that we were really moving at the last race and put 9 laps on the ield in oval against the 4.5.

can this system push a 6 lb. 1/8th scale off-roader?

Best bet would be to wait for the Mamba max truck version coming out soon , then you will definately not have any probs running a 1/8 off roader .

Back to the issue on speed , like i said different strokes for different folks but nothing compares to a low KV sensorless brushless system running high volts .

Higher KV systems like the Novak 4.5 and 3.5 can only run 6 cells as if you use more cells the motor will spin too fast and destroy itself.
So if your talking fastest systems around , look for a sensorless sytem with around 2500 KV which you can run over 16 cells no comparison.

so the design doens't meet roar rules? i'm not a big fan of roar, but i find myself running under their rules more often than not... can we get clarification on this? is it not approved, or will it not be approved?
