Once the original design work and templating has been done - (note that they are retaining those that started the company for now) the rest just becomes grunt work, so in all honesty they won't need the "tinkering" background for the company to be successful or profitable. I note Gippy Aero seemingly went through this process in it's early days as they employed many talented locals with aviation backgrounds to develop the components and procedures and now all that is left is low skilled process worker type jobs ( or at least so it would seem from an outsiders perspective ) Great effort by the likes of Morgan and White etc who have possibly made a stack of cash!
