Powering a 2200KV Mamba Monster motor(essentially a 4 pole Neu) with 6S Lipo will spin over 56,000 rpm. This is far above the recommended limit of 40,000 rpm for brushless( check out RC Monster forums for more info)
This MM motor is 75mm long So that would put it very close to the power of the Neu 1521(83mm length).
I run a 14.5 lb Supermaxx, complete metal with the 1521 on 5S and I can barely keep the front wheels on the ground. Even when going past 45mph the truck will wheelie and flip over, it has unbelivable torque!
Im only spinning 29,000 rpm. BTW, the truck runs completely cool with the MGM 224/18 ESC( The truck is on sale at RC Universe)
So if im only spinning 29000 rpm on a nearly 15 lb truck, what will 56,000 rpm do to a 10-11lb truck. Not to mention the extreme heat that it would create.
I would like to hear some opinions on this issue.
