Preflight
Check Your Radio
Before going to the field, be sure that your batteries are fully
charged per the instructions included with your radio. Charge
both the transmitter and receiver pack for your airplane. Use
the recommended charger supplied with your particular radio
system, following the instructions provided with the radio. In
most cases, the radio should be charged the night before going
out flying.
Before each flying session, be sure to range check your radio.
See your radio manual for the recommended range and
instructions for your radio system. Each radio manufacturer
specifies different procedures for their radio systems. Next, start
the motor. With the model securely anchored, check the range
again. The range test should not be significantly affected. If it is,
don’t attempt to fly! Have your radio equipment checked out by
the manufacturer.
Note
: Keep loose items that can get entangled in
the propeller away from the prop. These include
loose clothing, or other objects such as pencils and
screwdrivers. Especially keep your hands away from the
propeller.
Double-check that all controls (aileron, elevator, rudder and
throttle) move in the correct direction.
Check the radio installation and make sure all the control
surfaces are moving correctly (i.e. the correct direction and with
the recommended throws). Test run the motor and make sure
it transitions smoothly from off to full throttle and back. Also
ensure the engine is installed according to the manufacturer’s
instructions, and it will operate consistently.
Check all the control horns, servo horns, and clevises to make
sure they are secure and in good condition. Replace any items
that would be considered questionable. Failure of any of these
components in flight would mean the loss of your aircraft.
Flying the Jenny JN-4 Slow Flyer
You will find the Jenny JN-4 Slow Flyer to be a solid, honest-
flying model.
Ensure your CG is set according to the manual and power up
the aircraft. Move your throttle trim up slowly until the motor
just begins to spin. This will be your flight idle that will help to
establish a longer glide path and tends to make landings easier.
Before taxiing out to the runway, double-check all controls are
working in the correct direction and functioning properly. You
will find the rudder very effective; on the ground, tracking is
very predictable. Apply power smoothly and begin the takeoff
roll. Correct with rudder as necessary and apply up elevator
slowly until the model lifts off.
Note
: Please do not attempt to perform any aerobatic
maneuvers with your Jenny unless you have rigged the
model with the string as outlined in this manual on page
20. The string rigging is required for loops, wing overs
and other mild aerobatic maneuvers to ensure airframe
strength and longevity.
You will find flying the Jenny to be very relaxing and easy. The
model is not designed for high banked turns or high speed
flight. Most flight is accomplished below half throttle and will
yield flights in excess of 15 minutes with a 480 2-cell battery
with a Park 250 when outfitted with the GWS 6x5 slow flyer
prop. Landing the Jenny JN-4 Slow Flyer is as easy as setting up
on final approach, lowering the throttle to idle and gliding in to
a soft touch-down.
We hope you enjoy the experience of flying the Jenny JN-4
Slow Flyer.
Happy landings.
