Flying Your Alpha 450
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.
Age Requirements
Age Recommendation: 14 years or over. This is not

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.
daily Flight Checks
 1. Check the battery voltage of the transmitter
battery. Do not fly below the manufacturer’s
recommended voltage. To do so can crash
your aircraft.
When you check these batteries, ensure that you have
the polarities correct on your expanded scale voltmeter.
 2. Check all hardware (linkages, screws, nuts,
and bolts) prior to each day’s flight. Be sure that
binding does not occur and that all parts are
properly secured.
 3. Ensure that all surfaces are moving in the
proper manner.
 4. Perform a ground range check before each
day’s flying session.
 5. Prior to starting your aircraft, turn off your
transmitter, then turn it back on. Do this each time
you start your aircraft. If any critical switches are
on without your knowledge, the transmitter alarm
will sound a warning at this time.
 6. Check that all trim levers are in the
proper location.
 7. All servo pigtails and switch harness plugs
should be secured in the receiver. Make sure that
the switch harness moves freely in both directions.
