well this yoyo i got when i was only 11 and it was my second yoyo. i was so bored with it sleeping for 1 second and not being able to do anything with it except keeping it on the shelf. so i decided to play around with it.
first i took it all apart. theres only 5 pieces to the butterfly. the 2 wings the 2 caps and the axle. first i took a roller skate wheel axle and stuck it through the one side. and then i put 5 o rings on one side that i thought would really work a hub stack.(which didn’t actually work at all) and then i tried to put a roller skate bearing on the axle in between the 2 wings. didn’t work. so i thought to just put a roller skate bearing spacer in. so it would still be a fixed axle yoyo. which sort of worked. It comes back up sometimes. and does not sleep at all.
Well, in the long run this yoyo is about the same performance as it was before. i really didn’t lose anything, in fact i feel accomplished that this was my first mod and even though it was a failed mod, i’ll look at that and say I remember my first mod.
