extend the flight time by several minutes, especially if you fly
into a rising air current.

Because the Tutor flies slowly, it requires little room to land.
Begin the landing approach by flying downwind at an
altitude of approximately 20 feet [6 meters]. When the
airplane is approximately 50 to 100 feet [15 to 30 meters]
past you, cut off the motor power and make the “final” 180-
degree turn into the wind, aligning the airplane with the
runway or landing area. Do not dive the airplane, as it will
pick up too much speed. Instead, when you cut the power,
allow the airplane to establish a gradual descent.
Concentrate on keeping it heading into the wind toward the
runway. When the plane reaches an altitude of about 4 feet
[1 meter], gently apply a little “up elevator” to level the plane,
but be careful as too much up elevator will cause it to stall.
While holding a slight amount of up elevator the airplane will
slow and descend as it loses flying speed, thus touching
down on the runway.

Until you are able to accurately judge how far the Tutor can
glide, if flying with three channels (rudder only), it may be
helpful to reserve some battery power to run the motor so
the plane can be flown back to the runway.

When speaking of small models, frequently a takeoff from
the ground is called an “ROG” (rise off ground) takeoff.
Landings on grass will be a little rough, but doing a ROG
takeoff from grass will probably not be possible with the
Tutor. If planning an ROG takeoff, find a paved surface.

After you have trimmed the Tutor for flight and have become
familiar with its flight characteristics, you may execute ROG
takeoffs. With the model on the runway and pointing into the
wind, gently apply power. Initially, the plane may turn to the
left or right because it has not gained enough speed for the
controls to become effective. Do your best to get through
this brief moment and maintain a heading down the runway
and into the wind. Make corrections with the rudder to keep
it rolling straight into the wind. If the model veers too far off,
cut the throttle and try again. As the model begins to gain
speed the controls will become effective.

After the airplane has gained adequate speed (this requires
experience to gauge), gently pull back on the elevator stick
allowing the airplane to become airborne. Establish a gentle
climb the same as when you were hand-launching.

Best of luck and happy flying!
