I have a Qanba Q1 and i need sugest. It´s compatible this American Stick http://www.paradisearcadeshop.com/il-magnetic-stick/1476-il-magnetic-joystick-red-bat-silver-shaft.html with Qanba Q1?
What button can put from this stick 30MM?
It´s necesesary to change the wired to the buttons?
That happ joystick will not physically fit into a Qanba Q1 controller.
Use a Sanwa or Seimitsu joystick instead
The Q1 does use 20mm buttons, and its not necessary to change the wiring for the buttons.
@unaigalder : in the future, please don’t post the same question in multiple threads, though 
Darksakul was nice enough to answer you with detail.
And btw if you investigate Seimitsu sticks, try out the LS-40!
Are you sure that OBSC Sanwa 30mm button are not compatible?
Dude is wrong, they are 30mm buttons. the start button is 24mm
Just a typo dude.
its a Typo
I have put the Sanwa JLF in my Qanba with Sanwa restrictor gate Square.
What it´s the better option have less deadzone or i need to buy a Seimitsu Stick?
