Range Test your Radio
Before each flying session, and especially with a new
model, it is important to perform a range check. It
is helpful to have another person available to assist
during the range check. If you are using a Spektrum
transmitter, please refer to your transmitter’s manual for
detailed instructions on the range check process.
1. With the model resting on the ground, stand 30
paces (approximately 90 feet) away from the model.
2. Face the model with the transmitter in your
normal flying position. Be sure the throttle is in the
full down position and plug the flight battery into
the speed control.
3. As you move the controls, watch to be sure the
airplane’s motor and controls operate smoothly.
You should have total control of the model at 30
paces (90 feet).
30 paces (90 feet/28 meters)
4. If control issues exist, call the Horizon Support
Team at 1 877 504 0233 or go to

flying your Alpha Sport 450 PNP
The Alpha Sport 450 is a park flyer version of the
famous Hangar 9 Alpha trainer but with reduced
dihedral for a more spirited flight envelope. Takeoffs
are easily accomplished with the addition of full power
and a slight amount of up elevator. Takeoff rolls are
routinely in the 20–30 foot range with a strong climb
out. Once at altitude, trim the plane for level flight
at 3/4 throttle. You will find the model behaves in a
very benign way in all aspects of the flight envelope.
Inverted flight requires a fair amount of down elevator,
and the roll authority is quite good with the prescribed
high rate. This model is not capable of extreme
performance flight and was never designed for that.
Gentle majestic flight is its main purpose.
Landings are easily accomplished by reducing power
and gliding down to your favorite landing spot on the
runway with a very short roll out. We hope you enjoy
flying the Alpha as much as we do.
Happy landings.

Safety do’s and don’ts for Pilots
• Check all control surfaces prior to each takeoff.
• Do not fly your model near spectators, parking
areas or any other area that could result in injury to
people or damage of property.
• Do not fly during adverse weather conditions. Poor
visibility can cause disorientation and loss of control
of your aircraft. Strong winds can cause similar
problems.
• Do not take chances. If at any time during flight you
observe any erratic or abnormal operation, land
immediately and do not resume flight until the cause
of the problem has been ascertained and corrected.
Safety can never be taken lightly.
• Do not fly near power lines.
