HV-Maxx 4.5 or MM and 9xl?

[Serum]

But the statisfaction of the magnet is reached pretty soon on the hvmaxx.

It's got a tiny 12mm rotor;

You said a hvmaxx was more efficient than an XL;

but that's quite familiar on partial load with segmented/sintered magnets;

Did you take this into consideration;?

a 1000 watt setup at 93% eff. gets 70 watts of heat;
a 1500 watt setup at 95% eff. gets 75 watts of heat; while the 1500 watt setup is more efficient, though it will get more hot.

His point is simple Zero;

a motor delivers 50Ncm of torque at 2000Kv;
a motor that does 25Ncm at 4000Kv would have the same power.

Again; i used an 8XL on my 6Kg heavy savage without ANY heat issues on 16 cells, it's beyond the power a hvmaxx is ever capable of..
