New 4a Tutorial Series by Mr Yoyothrower

Okay, so I am working on the Arm Hop Repeater from the tutorial you posted here. However, every time I do the first hop, the yoyo falls off the string and ultimately falls out of the formation and onto the ground? Any tips on how to stop this from happening?

Best I can do without seeing a video of you doing the tricks is: Keep a firm grip on the string, keep each side of the string as straights and carefully lined up as you can. If you want to film yourself doing the trick and send it to me I might be able to help more. mryoyothrower@gmail.com
