Step 13
Using Elevator
Your Vapor 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 Vapor 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. Always seek the help of an
experienced radio control pilot if you are not familiar with pitch con-
trol. Failure to do so, could result in a crash and significant damage to
your airplane.
Step 14
Landing Your Vapor
When you begin to notice that your Vapor no longer climbs well under
full power (normally after approximately 10–15 minutes), the battery
is getting low and it is time to land. Bring in your aircraft toward the
desired landing spot. Gradually reduce throttle (as well as giving a
small amount of down elevator if you choose) to reach an altitude of
approximately 4 feet (1.2 meters). At this point, reduce even more
throttle and your Vapor should glide in softly for a landing.
Note: Your Vapor should be landed on a smooth surface (such as
concrete or wood) so that the landing gear can work effectively.
Rudder Trim
If the model wants to constantly turn in one direction, use the digital
trim buttons to correct. Your Vapor should fly straight with the control
stick at neutral. Always make trim changes in one-click intervals.
Elevator Trim
If your Vapor wants to go up or down, use the digital trim buttons
located to the left of the control stick to correct. 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
1. Climb to an altitude of 4–6 feet (1.2–2 meters) 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 throttle. 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.
