I would rather say I'm doing it in a different way as I know how all the systems work (especially on the full size) but saying that I will probably make up some sort of test rig for the reaction control nozzle system. Another reason I'm doing the fuselage first is that some have asked if I will be kitting it and having thought about it once the fuselage has flown first conventionally there's no reason why i couldn't knock out some kits at that point as the engine and systems for Vstol flight could simply be dropped into the fuselage at a later date as an upgrade kit..... that way I would be able to recoup some of the costs and reinvest it into the power plant.
