Well, its the setup I'm saving for to put it in my future touring car. I've finally decided to get the Cyclone Moore Speed World edition.

Whats the Mamba controller's RPM limit for a 4 poler?

I was thinking in the lines of a Plettenberg Shadow and a U-Force 75.

I know that the Shadow is 4 pole 600watt - 6200 RPM/V motor (probably unloaded RPM/V) with a 6-10 cell range with a 70,000 RPM limit quoted by Team Plettenberg when I asked what motor specs were in terms of Wattage - RPM/V - Cell Range - RPM Limit.

I know that the U-Force has a limit of 60,000 RPM for a 4 poler so I will probably have to run a 2S or like 8 cells, but I would really like to try to run it on 3s, but I know someone tried it and it didn't work or something.

they dont say on there site but i think i'm save when i say over 80k RPM for a 2 pole motor.

I hope that's 80K..

most controllers do 100-150K on a 2poler. while BK is sitting low with their micro 3095 and up series. (42K limit)

well what i mean is some people have run mamba max system up to 80k rpm, but its not so safe for the motor.
so 80k rpm is sure fact. could easiely be a lot higher.
