Check Vans. There is a document showing exactly where extra holes are allowed and dimensions.
 
Everyone

I think everyone is adding extra holes now. Add at least two, i thought I had it well planned with the existing holes, but had to add two extra. Easier to do it early in the build. Follow the Vans note. JMHO
 
I bought a QB kit , now it's difficult to do, but not impossible
I read in the documents , it's possible to make just 1 hole in each bay
in your opinion if I make 1 hole with diameter 1/2 inch at the center of the bay is it good ?
 
Me

I had to pass the three gps/ transpnder antennas thru one hole and the stick wires thru the other, so i made two extra holes one on each side of center tunnel. I think I went 5/8” and that was just enough for the three antenna coaxs. the two holes are not quite aligned because i drilled them after the plane was structurally complete.
