For soft field takeoff, use the normal takeoff procedures with the following exceptions:
1) Attitude
– Nose high to lift nose wheel clear of ground
2) Lift-Off
- as soon as possible
3) After Lift-Off
- LEVEL FLIGHT to obtain safe margin of airspeed prior to climb

The aircraft will lift-off at very low IAS but continued climb-out
below 35 MPH immediately after takeoff is not recommended.
CLIMB
1)
Throttle
- FULL OPEN
2)
Airspeed
- 35-50 MPH
For maximum performance climb, use full throttle and the following conditions:
BEST RATE OF CLIMB/BEST ANGLE OF CLIMB
1) Airspeed – 35 MPH
CRUISE
1) Level-Off - TRIM
2) Airspeed - ACCELERATE to desired cruise airspeed
3) Throttle - SET RPM to cruise power
DESCENT
1) Throttle
- REDUCE as desired
2) Airspeed - AS DESIRED
Descent should be made with a minimum of 3000 rpm to maintain cylinder head and exhaust gas
temperatures in green arc.

The Ascender’s thrust line is located above the aircraft’s
C of G which results in a mild increase in pitch attitude
when power is reduced. The effect is easily controllable
and results in a loss of about 4 mph in airspeed when power is
reduced from cruise to descent settings. Pilots should be
