Andrew, the post you placed is misleading about the JF 50Bee, in fact the Bee has been and is being flown constantly,single and twins (many Bees are being purchased for twin use) and if you want to see VIDEOS go to the link below!

Artes Jet is not needing nor wanting guys to be test beds, thats why its been over 2 years in the prototype stage, Artes Jets isn't new to turbines and for anyone of any seance will know that one motor running and working flawlessly isn't what is needed to manufacture and sale to the masses as we saw with ram 500.
Artes Jet Leading The Way.
