I posted the answer to your question a few posts up since I had the same question.
The LS-56/58 will mount in the Q4 using the P-40 mounting plate (it just fits). The only thing I don’t know is if the stick mounts with the correct shaft height since my knowledge is based on the fact that the RE plate can be mounted (RE plate and P-40 plate are practically identical except the RE plate is used for the LS-32/40 while the P-40 is used for the other compact Seimitsu sticks like the LS-56/58).
Hey what happened to the all seimitsu minsk art ice blue 3-in-1 Q4raf been checking to pre-order but can’t find, is there a release date for this one or was this version cancelled.
the seimitsu version as seen on the qanba website is generally available, but has obviously not been ordered by the various resellers.
Okay thanks for info will have to wait then.
well you could send a request to the resellers in order to get them to order this fine stick.
That’s nice…Any specific retailer or reseller?
Look for canadianjoysticks, focusattack, eightarc, videogamesnewyork and others.
I have replied you too. Thanks 
I just got the package. Trying to change the cabling with the map you sent me, xiang.
isn’t there another explanation for this? a youtube tutorial maybe?
edit: i replaced the little piece, but still doesn’t work.
well… i broke the pins, trying to get them out to switch their positions, since they were wrong.
nvm
Dear Xianglong the payment is already sent. Check your email inbox. Thanks!
we have received.
I have the white & red Q4 3-in-1 and I’ve noticed the stick is a bit squeaky (using stock stick). Anyone else experiencing this? It still works just fine, just a minor squeak.
I believe that’s semi-normal for a JLF.
Thinking of ordering a QanBa Q4RAF Limited Edition Red but the START button on Qanbas seem really close to the top row buttons.
Im worried in the heat of the battle it may get pressed accidentally … particular if I’m using Blanka / Honda and using the sliding technique for electricity / H.Hand slap.
Anyone tried to sliding technique and does the start button get in the way ?
nope … the start button has good distance from the other buttons unless you have incredibly long fingers. besides , most games are 6 button configurations. one would really have to have a bad eye hand coordination if he still feels that the start button is like just beside the regular buttons.
Hey, are we going to see 6 button perspex/mounting plates for the Q4? I’d like to get away from these button covers.
@Clone1B: I think I’ve seen that somewhere, but I don’t recall offhand. If I think of it I’ll let you know.
