Spinning a Flitzer
Since first flight, the 1834cc VW-powered prototype Flitzer Z-1 has flown over 70 hrs., without any changes to rigging or trim of the machine, other than for experimental purposes.
Handling is exemplary, controls being light and powerful, without the over-sensitivity associated with some small biplanes. The aeroplane has been dived to over 125 mph., controls firming-up appropriately, without any aerodynamic buzz, and terminal velocity appears to be well short of the flutter regime. It flies hands-off in the cruise (Vc = 86 mph.) and will complete a 360 deg. turn in 7 secs. at this speed.
At Vc, deliberate displacements in pitch, both positive & negative, result in stick-free re-acquisition of flightpath in 1/2 oscillation, ie. deadbeat damped in cruising flight.
