Geared properly, it's a touch faster than an overgeared 8xl at 20/51 in my ofna mbx which heated both the motor and the mamba max to 195 degrees in less than 5 minutes. I tested the limits of the novak motor and I got it to thermal in my 8ight geared 12/46 after 9 minutes of speed passes and the motor was only 160 degrees.
Neu motors are very similar internally to novak motors, so im sure they will be able to handle high rpm just find. IMO, the 2200 kv neu motor is very versatile. 2200 kv seems to be about right to be able to use almost the whole range of pinion gears on 4s. Gear down if you want less power. Then if you do want power, you can run 6s no problem. Since the neu motors are so much more efficient than feigao motors, you don't need to run 6s to keep things cool. 6s is only needed for maximum power.

The only thing I can say here is that the intention for most people to go with the 6s vs 4s isn't the "more power" argument as much as efficiency. By reducing the amp draw with higher voltage things just run better. I have no problem with the 2200 motor except on 6s. Some people may be fine with it, but I feel it's outside the motor's ideal efficiency. Especially if you're looking to race. Otherwise I'm sure you could have a lot of fun with it. I mean heck, who wouldn't think it's cool to see a 1/8 truggy blasting by you at 70mph?
