Mamba Max vs Novak GTB

[codieskid]

Hi Guys

I am going to get a brushless setup for my kyosho lazer zx-5 but am struggling to decide between a novak GTB of mamba max system.

I am very tempted by the mamba max but do you think a 7700Kv motor will be too powerful for the buggy. I am guessing here but i think this works out as about a 5 - 5.5 turn motor and would produce 46200rpm on 6 cells.

The next size down is a 5700kv motor which is about a 7.5 - 8 turn motor and would produce 34200rpm on 6 cells.

Finally there is the novak systems which have more options:
Turn speed KV
3.5 10,500
4.5 9,000
5.5 7,400
6.5 6,400
7.5 5,800

Which system do you think would be best suited for the ZX5 and whats the fastest motor you would risk?

Cheers
