OMGZ Brushless Revo!!! :O Need some advice :D

Speaking of A123's and voltages, surely there is a max RPM limit for each individual motor?

The reason I ask is that the kv rating on motors is the number of rotations per minute for 1 volt correct?

So if, for example, I end up getting a Feigao 9XL, which is rated at 1,853kv, and I use my 5S A123 packs which are 16.5v each, the RPM at max volts would be 1853 x 16.5 = 30574.5.

Is it just me or is that INSANE?!? Would that be too much for that motor, or do I have no idea? :D

The Mamba Max combo I'm getting (4600kv) says its alright for 3S lipo, which is 11.1v, but I can't find anywhere the actual stats on the motors, so if anyone has those, please let me know :D 4600 x 11.1 = 51060 RPM. Thats even INSANER!!!

Lol anyway, no more sugar for me, I'm wayyy to excited.
