ok i have alot of questions 
lol what hubstacks can the m1 yoyo have? and are they just as good as the 888 or g5 hubstacks, can i do everything i can with a 888 that on a m1 with hubstacks? thanks
You cant put hubs on M1ās. Iām not sure if you can put then on the old one, but you cannot put them on the new ones at all. Also, I wouldnt think that you could put them on the old one because of the axle.
the axle isnt the problem the nuts are pushed in with a 1 ton press geting them out would be a marvel to do without breaking the yoyo. (i had the same thought and researhed it)
Actually, after researching, you can do it, after extensively modding it,
