That is the point it won't be certified for commercial ops, hence a truly private machine. It will also get away from the current manufacturers competition on who can rip the owner off the most !
As for pretty limited market, just the opposite i think you will find, If you have £ 500k to spend what do you get ? 50 year old designed second hand 206 / 500. Have to spend at least that to buy an R66 or £ 1m plus on a 505, so if you are a private owner do you needed it commercially certified er NO.
It is really about time we as an industry stopped putting up with the overpriced crap that the current manufactures come up with. I guess at least Bell has tried to do something about it with the 505, but they wanted to certify it for commercial ops hence the price tag
