Best way to mount wing

meashure 1000000000000000 times, cut ONCE

just keep meashuring, and looking etc till u think it loks rite and drill it, if its off, then ohhh well, u beat it up cuz its fugly in ur bl buggy and buy a new one lol

for slipping, use a small (half the size or less) then the hole size u need and u should be fine there
