Hand Launch
For the first flight, it is a good idea to have a friend launch the
airplane for you.This allows you to keep your hands on the radio
sticks and correct any trim problems that are present.
Have your friend hold the YAK 55 by the canopy. Throttle up
to full power, and have your friend give the plane a gentle
underhanded toss at about a 30-degree angle upward.
Since the YAK 55 has a very high thrust to weight ratio, the
plane will accelerate to flying speed almost instantly. Climb
to a comfortable altitude and throttle back to a lower power
setting. This plane flies great at about half-throttle when in
standard forward flight.
For reassurance and to keep an eye on other traffic, it is a
good idea to have an assistant on the flight 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 fly more smoothly at reduced speeds.
Take it easy with the Great Planes Yak 55 for the first few flights,
gradually getting acquainted with it as you gain confidence.
Adjust the trims to maintain straight and level flight. After flying
around for a while, and while still at a safe altitude with plenty of
battery power remaining, practice slow flight and execute
practice landing approaches by reducing the throttle to see how
the model handles at slower speeds. Add power to see how the
Yak 55 climbs as well. Continue to fly 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 fine tune the model so it flies the way you like. Mind your
battery power, but use this first flight to become familiar with your
model before 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 final turn toward
the landing area (into the wind) keeping the nose down to

maintain airspeed and control. Level the attitude when the
model reaches an altitude of about 10 feet, 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 flare and the model is a foot or
so off the deck, cut your throttle and smoothly increase up
elevator until it gently touches down on its belly. Make sure
that you cut your power completely before touchdown, or
gearbox damage may result.
One final note about flying your model: have a goal or flight
plan in mind for every flight. 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 finding 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 flight plan greatly reduces the chances of crashing your
model just because of poor planning and impulsive moves.
Crashing
Even though the Yak 55 3D EP ARF is a very durable airplane,
learning to crash properly will extend the life of your airplane.
Since this is a 3D airplane, recoveries can happen in very little
altitude, so keep trying with power to recover until the last
possible second – you may find that you can "fly out" of a lot
more crashes than you thought. When you do know that
impact is imminent, cut your throttle – plowing the propeller
into the ground at full power will almost certainly strip out your
spur gear. Also, try to avoid allowing the airplane to build up
speed into a crash – keep the nose up and the speed down,
and the airplane will take impact in almost any attitude. Pound
it into the ground fast on the nose, however, and you'll be gluing
the nose section back on.
Have a ball! But always stay in control and fly in a safe manner.
