hi Charlie

You will need to make a venturie that is a bit thicker, mill the sides flat above the case and drill for a NVA that fits the span.  This is the way Super Tiger does the ones on the ST 51 and ST 34. I do not care for it at all, especially on a built up ship.
Or you can turn down a  ST 34 venturie to fit into teh OS

If it is an LAS all you need is a needle assy.  The OS one works.

If you want to use a Super Tiger type needle you'll have to drill the hole out as the OS stock diameter is .136, ST being 4mm (approx. .155).  This will also take some cross-section away from the OS venturi.

If it is an R/C conversion you will also need a venturi, Tower has those also.  Or if you need a smaller diameter than OS supplies you'll need to sleeve it down, make one, or get one from one of the specialty suppliers.
