Takeoff
Before you get ready to takeoff, see how the model handles
on the ground by doing a few practice runs at
low speeds on
the runway. Hold “up” elevator to keep the tail wheel on the
ground. If necessary, adjust the tail wheel so the model will
roll straight down the runway. If you need to calm your nerves
before the maiden fl ight, shut the motor down and bring the
model back into the pits. Top off your batteries, then check all
fasteners and control linkages for peace of mind.
Remember to takeoff into the wind. When you’re ready, point
the model straight down the runway, hold a bit of up elevator
to keep the tail on the ground to maintain tail wheel steering,
then gradually advance the throttle. As the model gains
speed decrease up elevator, allowing the tail to come off the
ground. One of the most important things to remember with
a tail dragger is to always be ready to apply
right rudder to
counteract motor torque. Gain as much speed as your runway
and fl ying site will practically allow before gently applying up
elevator, lifting the model into the air. At this moment it is likely
that you will need to apply more right rudder to counteract
motor torque. Be smooth on the elevator stick, allowing the
model to establish a
gentle climb to a safe altitude before
turning into the traffi c pattern.
Flight
For reassurance and to keep an eye on other traffi c, it is a
good idea to have an assistant on the fl ight line with you. Tell
him to remind you to throttle back once the plane gets to a
comfortable altitude. While full throttle is usually desirable for
takeoff, most models fl y more smoothly at reduced speeds.
Take it easy with the Sportster for the fi rst few fl ights, gradually
getting acquainted with it as you gain confi dence. Adjust the
trims to maintain straight and level fl ight. After fl ying around
for a while and while still at a safe altitude with plenty of
battery charge, practice slow fl ight and execute practice
landing approaches by reducing the throttle to see how the
model handles at slower speeds. Add power to see how
the model climbs as well. Continue to fl y around, executing
various maneuvers and making mental notes (or having your
assistant write them down) of what trim or C.G. changes may
be required to fi ne tune the model so it fl ies the way you like.
Mind your battery charge, but use this fi rst fl ight to become
familiar with your model before landing.
Landing
To initiate a landing approach, lower the throttle while on the
downwind leg. Allow the nose of the model to pitch downward
to gradually bleed off altitude. Continue to lose altitude, but
maintain airspeed by keeping the nose down as you turn onto
the crosswind leg. Make your fi nal turn toward the runway (into
the wind) keeping the nose down to maintain airspeed and
control. Level the attitude when the model reaches the runway
threshold, modulating the throttle as necessary to maintain
your glide path and airspeed. If you are going to overshoot,
smoothly advance the throttle (always ready on the right rudder
to counteract torque) and climb out to make another attempt.
When you’re ready to make your landing fl are and the model
is a foot or so off the deck, smoothly increase up elevator until
it gently touches down. Once the model is on the runway and
has lost fl ying speed, hold up elevator to place the tail on the
ground, regaining tail wheel control.
One fi nal note about fl ying your model. Have a goal or fl ight
plan in mind for every fl ight. This can be learning a new
maneuver(s), improving a maneuver(s) you already know,
or learning how the model behaves in certain conditions
(such as on high or low rates). This is not necessarily to
improve your skills ( though it is never a bad idea!) , but more
importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly fi nding that you’ve run
out of time, altitude or airspeed. Every maneuver should be
deliberate, not impulsive. For example, if you’re going to do a
loop, check your altitude, mind the wind direction (anticipating
rudder corrections that will be required to maintain heading),
remember to throttle back at the top, and make certain you
are on the desired rates (high/low rates). A fl ight plan greatly
reduces the chances of crashing your model just because
of poor planning and impulsive moves.
Remember to think.
Have a ball! But always stay in control
and fl y in a safe manner.
Good luck and great fl ying!
