With high power lipos, and the MMP I'll bet low 50's could have been possible. BTW I never had this setup have the motor go above 145.
In a mid-sized vehicle, with a big rotor, I think it would be good for any kind of reasonable speeds you want. I'm planning on gearing for around 55 with the Slash.

I have just upgraded an old HV4400 motor that was laying around, with the 5mm sintered rotor and matching endbell.

I put this in my E maxx with a MM Pro geared 14/52 using Mod 1 gears. Only being ran in the house so far, it's not completely clear just how well it's gonna do. Low speed driveability is smoother than re-churned butter.

Right now, it's being powered by 4S 4500mah Lifepo4.

The Magnetism of the new rotor is MUCH stronger than the old 1/8" shaft rotor.

I wonder what the new kv is and just how high can I go with the voltage?

Can it handle 5S or 6S if geared properly?
