I went around the Factory late last year and there was no sign of anything relating to the R66 and no discussion about it. Seems it's all in a restricted area.
No doubt, like other Robinson products, it will probably be a sales success in due course, but as ever, it doesn't mean it will be the best helicopter for the money (new or used).
Enstrom really should be marketing the 480B better, it's a very good package.
