Hey! I had a few questions about the rules for Launchers in the burst format. 

I checked the rules and couldn't find anything about the launchers themselvs. 
I was wondering if modded/home made launchers are allowed. if not, would a home made launcher GRIP be allowed? since it wouldn't interfere with the gears, or the launching mechanism, and would just add extra space for the hand? 

is there a section of the rules that addresses this and I just missed it?

My string launchers and Hasbro super grip launcher have been having major trouble recently and i cant afford to buy a new one(s).

Any help would be greatly appreciated! thank you!

Might be a bit disappointing for you but every tournament page says that Only official Beyblade (generation) burst gear allowed.
You can use painted casing of launcher and grip, manufactured by TT or Hasbro

Aw ok, thanks for the help
