Elevator Trim
If your Cessna 20 Centurion wants to go up or down, use the digital
trim buttons located at the left of the right control stick to correct
(see drawing). The model should fly straight with the control stick at
neutral and should have a steady, shallow climb at full throttle.
Step 12
Throttle Adjustment
. Climb to an altitude of 0–2 feet with full throttle.
2. To achieve and maintain a level “cruising” altitude, reduce the
power by moving the throttle stick down to approximately 50%
of full-on. The throttle stick is proportional, so you can add or
reduce throttle in small increments as needed to maintain the
altitude that you desire.
3. To reduce altitude, reduce throttle.
4. To increase altitude, increase throttle.
Step 13
Using Elevator
Your Cessna 20 Centurion is equipped with a third channel for
elevator (pitch control). Pulling back on the stick provides up elevator.
This allows for shorter takeoffs, better flares for landing, better climb
rates, and more effective turns. However, pulling too far back on the
elevator to climb too quickly will cause the airplane to enter a stall
(make the nose of the plane come down).
To avoid crashing from a stall, always maintain enough altitude to
recover.
Just after a stall has occurred, the nose of the airplane will fall and
the plane will look like it is diving. To pull out of a stall, simply pull
back slowly on the stick (partial up elevator) once your Cessna 20
Centurion has built up airspeed. Remember, pulling back too quickly
or for too long will once again cause the airplane to enter a stall.
Effectively avoiding and recovering from stalls requires experience.
