im using a servo tester with an 80A speed controller

i bought the motor as a 250kv at 2000w but a review i read has it at more like 1700w

i have two server power supplies at 12v 45A each... im hoping to stick with 12v to keep
the speed down for ally

i can use the smaller motor at 12v for up to 10000rpm

im also hoping to replace a 3.17mm shaft in a 4000kv helli motor with a 3.18mm shafted
engraving bit... not sure how practical this will be as ill have to strip the motor every time the bit wears out... worth a try if im desprate to do some really fine work
this one should run up to 48000rpm on 12v (i think) it will be interesting to see
how the bearings hold up

feel free to critiqe... im sure youll know more about these rc motors than i do
