View Full Version : Mamba question

Does anyone have a mamba 8000 on their h8? I hear that the h8 is super slow out of the box and it needs a better motor. I just wanted to know what people (who own the mamba) think about the performance. I would like to get my h8 around 35-40 mph. Can this be achieved with the mamba 8000 and maybe a 7 cell GP pack?

The 8000 is known to overheat in the H8. You would be better off with the 6800 and the 1100 8 cell saddle pack atteries and the stock pinion...... It's plenty fast enough!

I run a 5400kv BL Motor in one of our Half-Eights. This, along with an 8-cell GP pack is very fast.

We have even ran a 10-cell pack in it...and it is STUPID FAST!

Is it faster then with a lipo pack?

Thanks for your help.. I heard about cogging tho in the mambas so I might look into the aon.

depends on the lipo. It will be faster than a 2 cell but not three. But I would stick with the AON because it has a lot more torque and doesn't get as hot.

Sorry, what do you mean by "will be faster than a 2 cell but not three"?

You mean the speed by using 3 Lipo cells is similar to using 2 Lipo cells?

no, 2 cell is a lower voltage than the 8 cell gp battery. but a 3 cell will still have higher voltage while being a lighter battery. kinda responding to plian_simple's q.

...How fast does a Mini Inferno go with an Aon 4900 with 14t pinion, or the Mambas, 5400, 6800, 8000 with 11t pinion?
With 8-cell gp1100? 3-cell LiPo?

I am using the 4900 with 15t pinion and 8 cell matched gp pack. It is as fast as my rc18t was with 3 cell lipo and 5400 or 2 cell 8k. prob 30-40 mph, hard to say without a radar gun. But very fast and very worth the money.

15t pinon :eek:
Is your motor and ESC get hot ?? because I got the Golden Horizons 3600 Motor in last week, and I used 11t pinon. It go fast!! when I was play with my friend's Mini Quake yesterday. We have same motor and Mamba ESC, and I run 8cell. He used only 6 cell, but Mini Quake go very fast too !! However, My motor and ESC still got hot like 150F for the motor and 120F for the ESC. I just want to know is your set up get that hot too ??

*Assuming the previous user was asking if the 10-cell would be faster than a lipo.

Not sure if i agree with this statement. Here are my facts:

1. 3-cell lipo is 11.1v
2. 10-cell is 12V - Voltage Winner

3. Lipo pack, the best of the best will put out 20A.
4. GP cells can put out close to 30A. - Amp discharge winner

5. Lipo packs are lighter - Weight winner
6. GP (2/3a NiMH cells) are heavier

7. Lipo pack URC 1660mAh 11.1v $72.00
8 GP 10-cell 12V URC Pack $37.00 (estimated) - Cost winner

I would tend to lean towards the GP 10-cell pack would be faster due to the higher voltage and amp draw. But, Lipo will be more efficient, and provide longer runtimes.

All in all....if you run a 11.1v lipo pack or 12V NiMH pack, the bottom line is that you will have ONE FAST RC Truck/Car/Buggie.

I'm guessing that Moose's Aon is also getting a little hot with a large pinion...
Dunno about the motor's limits, but generally it shouldn't go over 200F, or it will start to demagnitize....Some people says that their Mamba-25 ESC gets so hot that the heatshrink melts off, so until then, nothing to worry about...
If your motor gets hot, try venting, making holes in the body and use a heatsink? :)

My ESC heatshrink did melt off with my Mamba Competition X motor then I change to Golden Horizons 3600 motor. After I change to motor, ESC do get cooler. Hoever, I still felt too hot for the ESC. Or may be I just worry too much :p . I think I will find a goog way to make it cool !!

Well of course it would be faster than the lipo. But I was not refering to 10 cells. I was refering to the 8 cell gp's that are made for the buggy

I measured the temp at 170 F after running non stop for 6-7 minutes with no vents in the body. This was a pavement run but dirt would be slightly more effort for the motor. This was the motor temp. I did not measure the mamba's temp but it was probably in the 120 range. I will cut some vent into the body and try some more runs with different mamba settings. I am running the lowest timing on the motor and normal startup power. The scary part is that the 17t pinion I have didn't cause anymore heat than the 15t

I was trying to use a 10T pinion for my mamba 8000k. But for some reason it just didnt sit right and stripped the gears. Is there a certain type of pinion i need?

you have to cut the inside of the holes where the screws for the motor mount go through. cut them in towards the center more.

would the Hacker Eflite E3-49 Brushless,4900KV go just as fast as the AON 4900?

I would guess no. I have not tested both together but my experience with eflite is that they have been much lower quality. Ask any electric flight person about eflite motors and they will tell you to stray away form them
