Throttle Adjustment:
1. Climb to a minimum altitude of 50 to 70 feet
(15 to 21 meters) at full throttle.
2. To achieve and maintain a level “cruising” alti-
tude, reduce the power by moving the throttle
slider down to approximately 70% of full on. The
Step 17
throttle slider 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 the throttle, and to
increase altitude, increase the throttle.
Using Elevator:
Your ParkZone ® Spitfire Mk IIB is equipped with
a third channel for elevator (pitch control). Pulling
back on the stick provides up elevator. 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 air-
plane 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 Spitfire
has built up airspeed as it decreases in altitude.
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. Always seek the help of an
experienced radio control pilot if you are not famil-
iar with pitch control. Failure to do this could result
in a crash and significant damage to your airplane.

Landing Your Spitfire
When you begin to notice that your Spitfire Mk IIB
no longer climbs well under full power (normally
after approximately 10–12 minutes), the battery
is getting low and it is time to land. Bring your air-
craft directly into the wind and toward the desired
landing spot. Gradually reduce throttle (and give a
small amount of down elevator if you choose) to
reach an altitude of approximately 10 feet
(3 meters). At this point, reduce the throttle even
more until it is eventually at no throttle and your
Spitfire should glide in softly for a landing. To avoid
damage to your aircraft, land on a smooth soft
surface, such as grass.
Expert Tip: As you get better and more experi-
enced at flying, try adding a bit of “up” elevator
just prior to landing to “flare” the plane.
With some practice, your landings should become
smooth and on target.
WARNING: Do not attempt to catch the airplane or
injury may occur. Remember, there is a spinning pro-
peller on the front of the plane that can cause injury!
Also, remember to cut power to the motor right
before landing to prevent damage to the propeller.
