What should we do with the axles and outrunners which I had to glue to prevent the propellers from slipping?

You are right that if the motor cores are wound by hand, not by the machine, it is shame to waste good cores which are very time consuming to wind. So I also think that saving them and rebuilding the motors is OK.

The batteries I use are Turnigy LiPo's, ranging from 2400 mAh to 4000 mAh. ESCs are Hobbyking SS 30A escs. The combination works fine except the bad bearings: they run fine and smooth, look nice but make noise and feel bad because of the bearings which makes me afraid of the motors and bearings seizing in-flight.

Dear TR,

Thanks for your mail, you are kindly, we will resend 5 sets bearings + 10pcs c clips + 2pcs BTS30 to you asap, the BTS30 are the gift, if you have any question you can feel free to contact us, thanks for your time. Nina
