That thread may interest you!
Many of the larger motors are around 500kv, these motors allow you to replace the motor shaft with the collet system.
You can use higher kv spindles but their diameter reduces and the vibration obviously becomes worse and needs balancing.
Another good spindle totally re made to test your engineering skills,

I have my 450kv motor running on a 24v power souce using a 100a speed controller, i rarely go over the limit of the power supply and trip it, but when i do its usualy an error!
There will be more experience people along soon to help with the bits i cant :) and of course welcome!
