Center of Gravity (CG)

An aircraft with correct CG has its weight balanced on the center of the
aircraft for safe, stable fl ight.
Balance the aircraft on your fi ngertips near the fuselage under the wings.
Adjust the battery position as needed.
- If the nose goes down, move the fl ight battery back until the aircraft
balances.
- If the nose goes up, move the fl ight battery forward until the aircraft
balances.

Flying Tips and Repairs

IMPORTANT: Even though SAFE technology is a very helpful tool, the aircraft
still needs to be fl own manually. If incorrect input is given at lower altitudes or
at slower speeds, the aircraft can crash.
Choose a Flying Field
In order to have the most success and to protect your property and aircraft, it is
very important to select a place to fl y that is very open. Consult local laws and
ordinances before choosing a location to fl y your aircraft.
The site should:
• Have a minimum of approximately 1300 feet (400m) of clear space in all
directions.
• Stay clear of pedestrians.
• Stay free of trees, buildings, cars, power lines or anything that could
entangle your aircraft or interfere with your line of sight.
Remember, your aircraft can reach signifi cant speeds when fl ying and can
cover ground quickly. Plan on fl ying in an area that gives you more space than
you think you need, especially with fi rst fl ights
Range Check your Radio System
Before you fl y, range check the radio system. Refer to your specifi c transmitter
instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for the fi rst time),
you will normally see the control surfaces react to aircraft movement.
In some fl ight conditions you may see oscillation (the aircraft rocks back
and forth on one axis due to overcontrol). If oscillation occurs, refer to the
Troubleshooting Guide for more information.
Hand Launching
When hand-launching your aircraft alone, hold the aircraft in one hand and the
transmitter in the other.
Apply about 1/2–3/4 throttle. Hold the aircraft on the underside and throw the
aircraft directly into the wind, angled slightly up (5 to 10 degrees above the
horizon). Climb to a safe altitude and check the trim. Once the trim is adjusted,
begin exploring the fl ight envelope of the aircraft.
Soaring
Your aircraft can ascend on thermals and other updrafts to prolong its fl ight
with the motor off. There are many ways to stay aloft with a sailplane, such as
ridge lifts and thermals.
A thermal is simply a column of rising warm air. Once you get your aircraft into
the air, watch your aircraft for a response to thermals. If the airplane randomly
rolls on its own, it is likely that you only fl ew through the edge of the thermal,
causing one side of the airplane to rise, rather than the entire airplane. Enter
the thermal by turning your aircraft directly into it, circling to stay in the center
of the thermal. Slow your forward speed by increasing up elevator trim so that
your aircraft is moving just faster than stall (minimum sink speed). Make easy
turns to fi nd the area of highest lift (the thermal's core).
10
When you fi nd the core of lift, tighten your turns to stay near this position.
Sometimes thermals drift downwind. It is best that you search for thermals
upwind, so that you can follow a thermal downwind if it is pushed downwind.
With practice, you will fi nd it easier to locate and anticipate the movement of
thermals. Although thermals cannot be seen, you can see dust, insects or birds
riding an updraft. Air movement of a thermal may be felt, so movement in an
otherwise calm spot may show you the location of a nearby thermal. A shift in
the wind (in a light breeze) can be airfl ow into a thermal.
WARNING: Do not dive your aircraft for prolonged periods of time. Doing
so could cause the aircraft to gain too much speed, and overstress of
the aircraft is possible.
Landing
Land into the wind. Due to the high lifting effi ciency of the sailplane design,
landing requires a large landing area clear of trees, buildings and cars. While
on your downwind leg, remember that the sailplane glides much better than
other aircraft.
You may need to setup for landing lower and with a more shallow decent than
you may be used to. As you are on approach for landing, ensure that the model
is descending slowly, but also not accelerating. If the model is accelerating, it
is likely that you will overshoot your projected landing area. Deploy the spoilers
during landing to help the sailplane descend faster.
Maintain this descent and speed, and, as the model nears the ground
(approximately 6 inches (15 cm)), slowly apply a small amount of up elevator.
The model should level out and fl y parallel to the ground, decelerating further.
Be sure the model does not climb. As it decelerates, keep fl ying the model
parallel to the ground until it comes to rest gently on its belly.
NOTICE: If a crash is imminent, reduce the throttle
fully. Failure to do so could result in extra damage to
the airframe, as well as damage to the ESC and motor.
NOTICE: When you are fi nished fl ying, never leave the
aircraft in direct sunlight or in a hot, enclosed area
such as a car. Doing so can damage the aircraft.
NOTICE: Crash damage is not covered under warranty.
CAUTION: Never catch a fl ying aircraft in your
hands. Doing so could cause personal injury and
damage to the aircraft.
IMPORTANT: Due to the effi cient nature of the Conscendo
it can be diffi cult to land in a small area. Plan the landing to allow enough
room for approach and allow space if the airplane does not descend as fast as
intended.
