Best climb speed (V
Y
) 70 kts (130 km/h)
Best climb rate at MTOM, sea level 590 fpm (3.0 m/s)
NOTE Climb rate is measured at a max continuous motor power of 40 kW with the flaps re-
tracted (0°) at V
y
and MTOM.
CAUTION! Remember to keep the motor/power controller/battery temperatures within op-
erational limits during climb. Avoid unnecessary use of high power settings if not necessary,
especially in high outside temperature.
Effect of outside air temperature
For every 5 °C (10 °F) increase in OAT versus the ISA, the climb rate decreases by 60 fpm (0.3 m/s).
Effect of altitude

Climb performance may vary depending on, temperature, altitude, humidity and wing & pro-
peller surface condition.
