Before Your First Flight
Before attempting to fly this aircraft for the first time, we recommend using the RealFlight Trainer Edition RC Flight Simulator (RFL1205, not included), to learn and practice the basics of flying. A spektrum transmitter may be connected to a PC for simulator use with a standard USB-C cable. Featuring six popular Horizon Hobby trainer aircraft and built-in Virtual Flight Instructor lessons, new pilots can learn to fly successfully by practicing on a PC at home or on a laptop just about anywhere else!
We also encourage you to connect with experienced RC pilots in your area through hobby shops or at designated flying fields. For those located in the United States, we recommend joining a national organization such as the Academy of Model Aeronautics (AMA). The AMA can provide information on local clubs, instructors and established flying sites in your area in addition to insurance coverage. Visit www.modelaircraft.org for more information.

Transmitter Trims
The included transmitter features digital trim buttons next to the control sticks to make fine adjustments during flight. The transmitter beeps when a trim button is pressed. The tone changes slightly when the trim value is centered. To quickly re-center the trims, press both the left and right sticks at the same time. If the aircraft drifts right or left in flight, use the opposite direction aileron trim button correct the drift. For example, if the aircraft drifts right in flight, press and release the left aileron trim button until the aircraft no longer drifts. If the aircraft climbs or dives during flight, press and release the down or up trim buttons until the aircraft flies level. If there is not enough digital trim available, mechanically adjust the in the control linkages to adjust the surfaces.

Flying

Consult local laws and ordinances before choosing a location to fly your aircraft. We recommend flying your aircraft outside in no greater than light winds. Always avoid flying near houses, trees, wires and buildings. Avoid flying in areas where there are many people, such as busy parks, schoolyards or soccer fields.
TIP: This aircraft can normally fly 6-8 minutes on a fully charged flight battery. This time will vary pending on your flying style, flight conditions and the condition of your battery.
Hand Launching
To hand launch the aircraft, place the aircraft in Beginner mode (only/always), and grip the fuselage immediately behind the wing. Advance to full throttle and give the aircraft a firm throw, slightly up (510 degrees above the horizon), and directly into the wind. After the model gains altitude and speed, decrease the throttle as you desire.

Takeoff Taxi the aircraft in position for takeoff facing into the wind. Gradually increase the throttle to full power. Hold a small amount of up elevator and steer with the rudder. When the aircraft lifts off, climb gently and adjust the trim for level flight. Once the trim is adjusted, begin exploring the flight envelope of the aircraft.
Landing Always land into the wind. Use throttle management to control the descent rate of the aircraft. During flare, keep the wings level and the aircraft pointed into the wind. Slowly lower the throttle while easing back on the elevator to bring the aircraft gently down on the main wheels.
NOTICE: Always fully lower the throttle at touch down when landing the aircraft. Failure to lower the throttle stick and trim to the lowest possible positions during a crash could result in damage to the ESC in the receiver unit.
Crash damage is not covered under warranty.

Repair this aircraft using CA glue or clear tape.
NOTICE: Use of CA accelerant on your aircraft can damage paint. DO NOT handle the aircraft until adhesive fully dries.
