DIY BLDC Motor

I made this as a project for fun really you will need 0.35mm copper enameled wire 3 M4 Bolts and 4 M4 locking bolts in addition an electronic speed controller (ESC) is required with a servo tester and a 12 volt drone battery or an external power source this is all guided by some 11mm x 5mm x 5mm ball bearings and a 5mm centre axle with a washer squashed between the stator and rotator . I would love for some constructive critiscism as iam only 14 and love to lear about different engineering and tech related things .
