KISS 912 flight test campain

We proceeded today to the second intensive test flights campain on the great KISS.
The version tested is the 1+1 with Rotax 912 – 80 HP. Complete cockpit. The cable visible is momentary, to mesure airframe deformations.
Outside temperature was +28 C, cross wind 15km/h.

KISS loaded with equiped pilot (Raphael) 90 kg plus 12 kg of fuel, total = 337 kg
KISS equiped with options such as : rear hydraulic brakes, engine cover and top firewall fairing, MGL Extreme + Garmin AERA + VHF + secondary airspeed / altitude + rotortack
Prerotation to 250 RPM / 3200 RPM on the engine. Propeller set at 12 degre. Rotor dia. 8.4m
T.O distance repeatedly made in 30 meters at 60 km/h
Machine Takes Off in quite level position, no pitching tendency.
Climb speed 85 km/h – 600 ft/mn.
Cruise speed 120 km/h at 5000 RPM, rotor at 320 RPM.
Top speed actual 145 km/H with 5750 engine RPM, rotor at 350 RPM, verified GPS, propeller needs more pitch.
Pitch stability perfect, no need of trims
Roll stability perfect
Yaw stability positive, perfect. Flies and turns, feet on the floor. No need of any coordination.
Full rudder applied both ways, machine returns to neutral itself. No side wind effects on the cockpit.
Thermal activity and turbulences having no effects.
Throttle changes = no PIO, ultra stable. The “T” handles that perfect, as for the XENON.
Joystick forces in the midle range, positive feedback.
Action to increase power = gentle climb ; decrease of power = gentle descent. Perfect.
Tight manoeuvres banks up to of 45 degres, all perfect handling. Smooth and docile.
Vibration level ultra low. Noise ultra low.
Pilot comfort : outstanding ergonomics, no noticable cockpit turbulences.
Fuel consumption estimated around 12 l/h
Total flights times : 2 hours.

Resume : The KISS can be declared as a new winner. Ultra easy handling, all manoeuvres are a breeze and an amazing delight. Feels to fly that KISS for hours non stop, as the global comfort is so high.

We will now keep going on our testing, and improve the finish.
Was a great super day. I am impatient to test the next version 100 HP ! Probably end next week.
