It seems that if one dove (tilted the rotor forward) quickly in forward flight that the air flow might be able to enter thru the top of the rotor and stall it (or even cause it to rotate backwards). Is that the case?
@tsbrownie - if the airflow is reversed over the rotor as you describe, the result is called a 'buntover'. This is a serious problem for the pusher-prop 'Benson' style gyros, but much less so with tractor gyros. The original tractor gyros of the 30's (Invented by De La Cierva, a Spaniard!) had an excellent safety record (unlike the Benson or pusher style gyros), and from the looks of the Phenix, this one should as well.
@MrRabit1993 - This video seems to be demonstrating that a giant of a man, 6'3" 220 lb, plus a more typical man, can both fly in this gyro. Since this is the first Phenix prototype, the prerotator and other systems may not have been quite up to speed. Later videos depict a more typical gyroplane short take-off.
It needs a prerotator to shorten the takeoff roll; when autogyros don't have prerotators they are capable of landing in places they can't take off from
fix a minigun and some misslies on it and go to Iraq.

It appears that you use too much runway

Engine is a Rotax 914, turbo-charged and as any other gyrocopter it cannot hover but also does not stall so it can be landed in auto-rotation.
