Thanks Nick...
You know as well as most that the
PR machines of big buisness are the ones who drive industry.
If the product 'looks good' it will sell, .... put a pretty blonde at the controls of an R22 and even I could be persuaded to buy one, add the catch phrase 'safety' to it and bingo, you have a seller.
What I was aluding to above, was the fact that if someone is going to purchase a NOTAR, for whatever reason, (whether based on a 'safety' sales pitch, because it looks good, or because they have always wanted one) then putting in larger engines etc to increase hover performance may be an option to the would be buyer.
With that in mind, I guess really big NOTARs are possible...
