 Acceleration and deceleration check - with mixture set to RUN, advance throttle from idle to
2300 RPM. Engine should accelerate and decelerate smoothly with no tendency to backfire.
 Carburetor ram-air control lever set to RAM AIR (UNRAMMED FILTERED AIR or carburetor HOT
AIR control lever set to HOT AIR only if required).
 Mixture control set to RUN.
 Supercharger control switch set to AUTO.
 Oil and coolant radiator air control switches set to AUTOMATIC.
Do not exceed 40 in.Hg during ground run-up without having the tail tied down, because
of the possibility of the aircraft nosing over.
Takeoff
Normal Takeoff
Follow the below procedure to perform a normal takeoff:
 Be sure takeoff area is clear and check final approach for inbound aircraft.
 Release brakes and line up for takeoff.
 Advance throttle smoothly and steadily to Takeoff Power (61 in.Hg MP at 3000 RPM).
 Do not attempt to lift the tail too soon, as this increases torque action. Pushing the stick forward
unlocks the tail wheel, thereby making steering difficult. The best takeoff procedure is to hold
the tail down until sufficient speed for rudder control is attained and then to raise the tail slowly.
Slight rudder input may be necessary to control P-factor effects as the tail is lifted and stabilized
for a takeoff attitude.
Note, it is recommended that 61 in.Hg and 3000 RPM be used for all takeoffs and that this power
setting be reached as quickly as possible after the takeoff run is started. However, advance the
throttle smoothly and never jam it forward, as torque effects appearing from a sudden onset of
power will cause a loss of control of the aircraft.
When a formation takeoff is performed, a lower power setting of about 55 in.Hg may be used to
allow the wingmen room for increased power over the leader in order to maintain their position.
If rough engine occurs during the takeoff run, immediately throttle back 4 or 5 in.Hg manifold
pressure to complete takeoff if conditions permit. Throttling back tends to decrease the intensity of
detonation or preignition and minimizes the chances of engine failure. If this condition occurs on
takeoff, the spark plugs must be changed before the next flight.
Avoid sudden bursts of power during takeoff! Make it smooth and steady.
