The mamba is sensorless

The best brushless systems in the world are Lehner then hacker, but these are sensorless so there not ideal for tc or 12, the ones you mentioned are pretty much the same so its down to your manufacturer preference.

whats the problem of sensorless?
thanks

No. "problem".. just different.


If you want to race, then you will need to go with a sensored motor. Why?
Because racing is governed by several organisations that require certain design specific in both car, battery, motor etc. to keep the racing comparible.

The sensorless systems are king when it comes to outright power. The most powerful systems out there are all sensorless. However, there is a price to pay in terms of the throttle response.

Car racing requires very fine motor response, and the sensorless systems do lag behind the sensored system a little in this regard. They're close, not not close enough.

That said - any top levelmotor from LRP, Novak, GM, NOsram etc will be more than enough for most people.

Both the LRP and Novak have good reports.. (As well as bad)..

I personally use the Novak GTB and haven't had a problem so far.
I've also owne the 5800ss, and the 5.5R motor and didn't have problems with those either.
(Currently run the GTB and 4.5R)

Hope that helps..

The GM brushless works really well and is king when it comes to racing it's power output is unbeaten under the legal systems.

I testet both sensored and sensorless. There wasn't much difference. Works both really well.

I currently use either 3,5T Motor during practice (with the "bad" batteries) and 4,5T at races with the IB World Champion packs.

I run a GTB with a 4300 with no trouble. I'm geared to the safe side. Gearing is what makes or breaks any of these setups. I believe their all good products.

Novak GTB hands bown! :nod:

try using IB World Champion cells ... then you know what's really going on :lol:

our local track just ran a 24 hour enduro, novak, tekin and hacker brushless motors were used, none failed. there was one tekin, one hacker, and serveral novaks, the couple of cars that didn't run brushless, some switched to the novaks, (thanks novak for the support) the tekin was/is senorless. none of the drivers (eight per team) reported a lag or anything like that with the tekin.
personally i use the lrp comp speedo with a novak brushless, size does matter, the gtb just takes up to much room in my yok bx.

I think the best actual system for racing is the GM/orion!! The advantage over others is that you can change parameters with a computer so it's very adjustable on each track.
The only problem is just that is hard to find.

GTB/4.5 hands down!
 
Having started with a Neo One 3 star/Sphere and that ESC frying on me within a week, I opted for the GTB/4.5. Difference was night and day. I did run the 3 star on the GTB b4 installing the 4.5, totally BETA. Motor ran nice, but when I installed the 4.5, it was off to the races! I have seen the Mamba and it is sick, but clearly for bashers/balls out runs. The footprint of the GTB is a bigfoot compared to the Sphere. And whatever you do, if you get the GTB, make sure you run a cap, and keep the ESC and receiver mounted as far away as possible.

is there any info and details of gm bl sys?
thanks

I have owned the Novak SS5800 with the SS Upgrade Kit (makes equivalent to the SS5800+), the Novak GTB with 5.5R, and the Mamba Max 5700. This is just my opinion, but I prefer my Mamba Max over the Novaks. Make part of your decision based upon where you're going to race because as many mentioned above the sensorless systems like the Mamba, Lehner, & Hacker systems are not ROAR legal. I will tell you that from my experience from all three of these systems, that I am very impressed with the smoothness and throttle response of the Mamba. Plus, the flexibility you have in terms of the programming and the lack of "planned obsolesence" on Castle Creations behalf. The other benefit of the Mamba is that I haven't gotten it to thermal, yet. The Novaks would thermal every so often even when staying within their recommended gear ratios. Another advantage of the Mamba is the pricing. I don't think you will find any of these other setups cheaper than the Mamba and keep in mind that they also offer awesome customer service. I've also tested out my friend's LRP Sphere with the Reedy Neo motor and I must say this had a throttle response and smoothness very similar to the Mamba. The only problem with the LRP is if you plan to use reverse, reverse doesn't work too well on the LRP as there isn't much of a delay between braking and reverse. I know this sounds pretty biased towards the Mamba, but this is from my experiences with these four systems.
