mugenkidd, I'd answer about plumbing but I'm early in the construction and also going ducted fan instead of turbine (this is my first jet). Let's see some pictures of yours and maybe that will get conversation started

BTW, did you strip the paint off your jet before you gave it a T-45 scheme? If so, how did you strip the paint? I was thinking acetone...I just want to re-do the Red Arrows scheme better on mine.
Anybody know of a remote needle valve assembly for the OS 46 VX-DF? I'd like to mount one but I can't find any while doing a net search.
Didier, your link is somewhat confusing...I only see a business consulting firm advertisement. Is there a link on that page to follow?
