Dave,
Happy new year.
While the concept intrigues me, in the real world my time is precious and i imagine most folk fall into the same category. I am about to take a up a project at "the other end of the transportation spectrum", where we are already working with globally distributed engineering design teams. That and still having two more courses to complete my physics degree means that flying already sits uncomfortably on the back burner
The real question has to be how serious are you? You have come up with many proposals, since first introducing me to PPrune (thanks for that BTW). I realise you are serious about manufacturing composite blades, but a whole light heli requires a new level of dedication to detail. There is something to be said for having a definate timeline and budget, although i realise the idea is to avoid this. For a start there is a commitment to finding the best idea, then sticking with it until it performs. My real concern is that this would just become an exercise is documenting ideas, but nothing would ever actually fly.
