wont work with a 4s...states the max voltage is 11, so 3s would be your cap

Yes, 3s, whatever size bat you like. You could even use a 20amp esc.

YES NOT A PROBLEM I WAS USEING IT WITH A 30AMP AND RAN FINE , BUT DIDNT GET TO MUCH POWER FROM THE 7 BLAD FAN SO I HOPED IT UP TO A 4S BATTERY AND DIFFERANT MOTOR SYSTEM.

The 2,3mm shaft is 3mm, exept for the last ~12mm that is grinded down to right diameter. No need to change bearings.
There is a grub screw at the bell that must be removed, then it has been easy (at lest for me) to grab the shaft with a plier (not a wire cutter!) and rotate/pull out the shaft. When installing the new shaft, be sure the grove is in the right place, so the grub screw sequre the shaft properly.

Since its rated as max 11v, I wouldnt recommend trying it on 4S. Also, with a max rated current of 12.9 amps I would say its very under rated for a 70mm fan. As a comparison, I have a 63mm fan running a 3800kv motor on 3S - it draws 53 amps static and about 35 amps in the air, for a top speed of around 170km/hr from a small 500 gram delta wing jet.
