Two of the most important things you can do to preserve the

radio controlled aircraft hobby are to avoid fl ying near full­scale aircraft and avoid fl ying near or over groups of people.

PROTECT YOUR MODEL, YOURSELF

& OTHERS… FOLLOW THESE

IMPORTANT SAFETY PRECAUTIONS

INTRODUCTION

Thank you for purchasing the Cessna 350 Corvalis. Originally

produced by Columbia aircraft and called the Columbia 350,

the design was recently purchased by Cessna and was

renamed the Cessna 350 Corvalis–after the name of the

town near where it was being manufactured. After opening

the box, you will no doubt be anxious to see the sleek lines

of this modern single-engine aircraft come together on your

work bench. Fortunately, all of the time-consuming work has

already been done for you. Innovative assembly methods

allow this plane to virtually fi nish itself in under an hour.

Once at the fi eld, you will fi nd that the Cessna fl ies smoothly

but with authority from the pre-installed brushless outrunner

motor and LiPo battery.

For the latest technical updates or manual corrections

to the Cessna 350 Corvalis, visit the Flyzone web site at

www.fl yzoneplanes.com. Open the “manuals” link, then

select the Cessna 350 Corvalis.

1. Your Cessna 350 Corvalis should not be considered a toy,
but rather a sophisticated, working model that functions very
much like a full-size airplane. Because of its performance
capabilities, the Cessna, if not assembled and operated
correctly, could possibly cause injury to yourself or spectators
and damage to property.

2. You must assemble the model according to the instructions.
Do not alter or modify the model, as doing so may result in
an unsafe or unfl yable model. In a few cases the instructions
may differ slightly from the photos. In those instances the
written instructions should be considered as correct.

3. If you are not an experienced pilot or have not fl own
this type of model before, we recommend that you get
the assistance of an experienced pilot in your R/C club for
your fi rst fl ights. If you’re not a member of a club, your local
hobby shop has information about clubs in your area whose
membership includes experienced pilots.

4. While this kit has been fl ight tested to exceed normal use,
if the plane will be used for extremely high stress fl ying, such
as racing, or if an engine larger than one in the recommended
range is used, the modeler is responsible for taking steps to
reinforce the high stress points and/or substituting hardware
more suitable for the increased stress.

We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.

BEFORE YOU BEGIN

Before you begin assembling your Cessna 350 Corvalis,
thoroughly read the instruction manual included with the
battery charger. Also familiarize yourself with the following
lithium polymer battery cautions. When satisfi ed with your
understanding of the battery charge process and safe
handling of LiPo batteries, charge your fl ight battery so it will
be ready to use when your assembly is complete.

LITHIUM BATTERY HANDLING AND USAGE

WARNING!! Read the entire instruction sheet included
with your battery charger. Failure to follow all instructions
could cause permanent damage to the battery and its
surroundings, and cause bodily harm!

• ONLY use a Li-Po approved charger. NEVER use a
NiCd/NiMH peak charger!

• NEVER charge in excess of 4.20V per cell.

• ONLY charge through the “charge” lead. NEVER charge
through the “discharge” lead.

• NEVER charge at currents greater than 1C.

• ALWAYS set charger’s output volts to match battery volts.

• ALWAYS charge in a fi reproof location.

• NEVER trickle charge.

• NEVER allow the battery temperature to exceed 150° F
(65° C).

• NEVER disassemble or modify pack wiring in any way
or puncture cells.

• NEVER discharge below 3.0V per cell.

• NEVER place on combustible materials or leave
unattended during charge or discharge.

• ALWAYS KEEP OUT OF REACH OF CHILDREN.

ASSEMBLE THE MODEL

1. Insert the wing joiner into the wing pocket of one wing

❏

panel. Be sure that the “V” shape of the joiner points toward
the underside of the wing.

2. Fit the other wing panel onto the wing joiner.

❏

3. The aileron and fl ap pushrod wires must pass through

❏

the holes in the screw lock connectors when the wing panels
are joined together.

5

4. Tighten the wing joiner screws that can be seen through

❏

the access holes in the underside of the wing panels.

6. Connect the Y-harness to the wing lights as shown.

❏

7. Using the included piece of double-sided foam tape,

❏

install your receiver onto the radio tray as shown. Installing a
receiver other than the model shown may require you to trim
the tray in order for it to fi t. An antenna tube is installed in the
fuselage if you will be using an FM radio system.

5. Position the fl aps and ailerons inline with each other

❏

(left aileron and right aileron even with each other, left fl ap

and right fl ap even with each other) and tighten the screws in
the screw lock connectors. Note: After the receiver has been
installed and you test the operation of the fl aps and ailerons,
you may need to loosen the screws, reposition the pushrod
wires in the screw lock connectors, and retighten the screws.

8. Connect the servo leads into their appropriate channels

❏

on the receiver. The Y-harness for the wing lights can be
plugged into any remaining unused channel of the receiver.
Note that the Y-harness does not have a white signal wire as
the servos do.

6

9. Insert the wing dowels into the holes in the fuselage

❏

at the front of the wing saddle. Make sure that none of the
servo wires interfere with the tail servos. Press the wing
into place and attach it to the fuselage using two 3x22mm
machine screws.

11. Unscrew the bottom half of the nose wheel pant.

❏

10. Mount the landing gear to the fuselage using four

❏

3x16mm self-tapping screws.

12. Insert the nose wheel axle through the nose wheel and

❏

fi t it into the grooves in the lower nose wheel pant. Replace
the lower nose wheel pant and screw it back into place.

7

13. Slide the left horizontal stabilizer onto the fuselage.

❏

Align the plastic fi ttings into their mating slots in the fuselage

and press the stab half against the fuse until fully seated.

15. Remove the spinner cone by unscrewing the two

❏

screws that hold it to the spinner backplate. Install the
propeller followed by the prop washer and then the prop nut.

Thoroughly tighten the prop nut. Reinstall the spinner cone.

14. Install the right horizontal stabilizer in the same

❏

manner. Thread a 2.5x8mm self-tapping screw into each
stab mounting hole and tighten them securely.

16. Install the antenna onto the underside of the fuselage.

❏

Apply a couple drops of glue to the base of the antenna

before fi tting it in place. CA, epoxy, white glue, hot glue, or
any other household glue would be acceptable.

8

PREPARE FOR FLIGHT

1. Remove the cowl top by grasping it through one of the

❏

front cooling holes and lifting up.

3. Turn on your transmitter. Move the throttle stick to the

❏

middle position (50% of stick travel). Each and every time
before you plug your fl ight battery into the ESC you must be
sure that the propeller is free of anything that could interfere
with its rotation and is pointed in a safe direction. Note: If you
are using a Futaba radio, move your throttle channel servo
reversing switch to the REVERSE position.

4. Being careful to keep your hands clear of the propeller

❏

arc, plug the battery into the ESC. Reinstall the cowl top onto
the fuselage and confi rm that it is securely clipped into place.

Check the Control Directions

As described in the previous section, your throttle stick should
still be in the middle position. When checking the control
directions, keep the throttle stick in this position to avoid
arming the ESC until you are ready to operate the motor.

2. With your battery fully charged, slide it into the battery

❏

compartment as far as it will go. Secure the battery with the
hook and loop strap attached to the battery compartment.

Do not yet plug the battery into the ESC!

1. Viewing the model from behind, move the rudder stick

❏

to the right. The rudder should move to the right as shown. If
it does not, change the position of the rudder channel servo
reversing switch.

9

2. Move the elevator stick down. The elevators should

❏

move up. If they do not, change the position of the elevator
channel servo reversing switch.

5. With the trim levers all in the neutral position, confi rm

❏

that the control surfaces are still centered. If necessary,
remove the wing from the fuselage and make adjustments
to the positions of the pushrods in the screw lock connectors
to re-center the control surfaces. Double check that the left
fl ap and aileron are inline with the right fl ap and aileron.

Set the Control Throws

3. Move the aileron stick to the left. The left aileron

❏

should move up and the right aileron move down. If they do
not, change the position of the aileron channel servo
reversing switch.

4. Flip the fl ap switch (or whatever dial or slide you have

❏

chosen to use if applicable) toward you (or down depending
on the orientation of the switch on the transmitter). The fl aps
should move down. If they do not, change the position of the
fl ap channel servo reversing switch.

Use a Great Planes AccuThrow™ (or a ruler) to accurately
measure and set the control throw of each control surface
as indicated in the chart that follows.

NOTE: The throws are measured at the widest part of the
elevators, rudder, fl aps and ailerons. If you are using a ruler
to set your control surface throws, the defl ection distance
is measured as the height from the center trailing edge of
the control surface when moved from the neutral position as
shown in the sketch. Defl ection in degrees is also provided
for an alternative measuring method.

These are the recommended control throws:

IMPORTANT: The Cessna 350 Corvalis has been

the Motor

extensively fl own and tested to arrive at the throws at
which it fl ies best. Flying your model at these throws will
provide you with the greatest chance for successful fi rst
fl ights. If, after you have become accustomed to the way
the Cessna fl ies, you would like to change the throws to
suit your taste, that is fi ne. However, too much control throw
could make the model diffi cult to control, so remember,
“more is not always better.”

Operate the Motor

Check the C.G. (Center of Gravity)

The C.G. (Center of Gravity) is the location on the wings,
measured back from the leading edge on both sides of
the fuselage, where the model balances. In addition to the
control surface throws, the C.G. has a GREAT effect on the
way the model fl ies. If the C.G. is too far aft (tail heavy), the
model will be too responsive and diffi cult to control. If the
C.G. is too far forward (nose-heavy), the model will be too
stable and not responsive enough. Follow the instructions
to make sure the model is balanced properly and the C.G.
is in the correct location.

1. Move the throttle stick to the middle position and plug

❏

the battery into the ESC. Move the throttle stick to the idle
position. The ESC will make an audible tone (either one tone
or two tones). Assume now that the ESC is armed and the
propeller will rotate when the throttle stick is advanced!

2. With a fi rm grip on the tail of the plane and the propeller

❏

pointed in a safe direction, slowly advance the throttle stick.

The propeller should begin to rotate. If it does not, return the

throttle stick to the idle position, disconnect the battery, and
fl ip the throttle channel servo reversing switch.

3. Move the throttle stick to the middle position. Reconnect

❏

the battery. Move the throttle stick to the idle position. With a
fi rm grip on the tail of the plane, slowly advance the throttle
stick and confi rm that the propeller rotates.

4. The ESC is equipped with a BRAKE feature. We

❏

recommend fl ying the Cessna with the brake OFF. When
the ESC is armed, one beep indicates the brake is off. Two
beeps indicate the brake is on. To toggle the brake on and
off, fi rst disconnect the battery from the ESC. Advance the
throttle stick to full throttle and reconnect the battery. After
a few moments, the motor will emit a tone (one beep for
brake off, one beep for brake on). Move the throttle to the
idle position to arm the ESC. If you wish to toggle the brake
feature on or off again in the future, repeat this step.

Note: The motor is connected to the ESC at the factory to
rotate in the correct direction. If at any time you disconnect
the motor from the ESC for repair or replacement and the
motor rotates the wrong direction, simply disconnect any
two of the three motor leads and swap their positions.

5. Disconnect the battery from the ESC but leave the

❏

battery installed in the fuselage to check the C.G.

1. Place pieces of masking tape onto the top of each wing

❏

panel. Measure back from the leading edge of the wings
where they meet the fuselage and draw three lines onto
each piece of tape using the measurements shown. These
three lines represent the forward limit, recommended and aft
limit C.G. positions.

2. With the battery and cowl top installed, place your

❏

fi ngers on the middle balance marks, turn the plane upside
down and lift the model. The fuselage should remain level—
it may be helpful to have an assistant view the model from
the side (or have your assistant lift the model) to see if it
is level. If the nose of the plane drops, move your fi ngers

11

forward of the middle lines and recheck the balance. If the
tail of the plane drops, move your fi ngers aft of the middle
lines and recheck the balance. As long as the plane will
balance with your fi ngers somewhere between the forward
and aft lines, the Cessna will be safe to fl y. We recommend
that the plane balance at or close to the middle lines, at least
for your fi rst few fl ights. Add weight to the nose or tail of
the plane as necessary until the plane balances with your
fi ngers on the middle lines. If the tail drops, nose weight
will be required. If the nose drops, then tail weight will be
required. The best way to add weight to balance the model
is to place segments of stick-on lead weight on the fuselage
wherever it may be needed. For this, Great Planes stick-on
lead weight (GPMQ4485) should be used.

5. Recheck the C.G. to make certain the model still

❏

balances where required. Once fi nished, remove the battery.
Never charge the battery while it is installed in the model.

6. Later, once you become an expert at fl ying your Cessna,

❏

you may change the fl ying characteristics by changing the
balance point—but do not go beyond the marks you already
made on the top of the wing. Moving the C.G. forward (nose
heavy) will improve the model’s stability. This could be an
advantage on breezy days. Moving the C.G. aft (tail heavy)
will make the model more sensitive to control input.

Identify Your Model

No matter if you fl y at an AMA sanctioned R/C club site or
if you fl y somewhere on your own, you should always have
your name, address, telephone number and AMA number on
or inside your model. It is required at all AMA R/C club fl ying
sites and AMA sanctioned fl ying events and simply a “good
idea” even if fl ying somewhere else. Write this information on
a strip of masking tape and place it on the inside of the cowl
top (or simply write the information directly on the inside of
the cowl top).

3. Determine the amount of weight required by placing

❏

segments over the cowl or tail where shown, but do not
attach the lead yet.

4. Once you can get the model to balance and you know

❏

how much lead will be required, permanently stick it into
position. If nose weight is required, you could simply stick it
to the bottom of the fuselage just in front of the nose landing
gear. If you prefer the lead to be concealed, stick it out of
the way in the battery compartment. If tail weight is required
simple adhere it to the underside of the horizontal stabilizer.

FLYING THE CESSNA 350 CORVALIS

Although the Cessna 350 Corvalis is an extremely sturdy

airplane made of durable foam construction, its low wing
confi guration does not have the self-righting characteristics
of a trainer plane and is therefore not recommended for
beginner pilots. The Cessna is, however, easy to fl y even for
pilots with moderate experience. If you have not previously
fl own a trainer it is strongly suggested that you learn to fl y with
one fi rst. Or, get the assistance of an experienced pilot to help
you with the fi rst few fl ights (or however many it takes until you
are profi cient with the entire fl ight from take-off to landing).

After the range check, fully extend the antenna.

Note: If you are using a 2.4GHz transmitter, consult your
radio manual for the proper range checking procedure.

Monitor Your Flight Time

Monitor and limit your fl ight time using a timer such as the
one on your wrist watch. When the batteries are getting low
you will usually notice a performance drop before the ESC
cuts off motor power, so when you notice the plane fl ying
slower you should land.

Find a Suitable Flying Site

Find a fl ying site clear of buildings, trees, power lines and
other obstructions. Until you know how much area will be
required and have mastered fl ying your Cessna in confi ned
spaces, a site at least the size of two or three football fi elds
should be adequate—a fl ying fi eld specifi cally intended for
R/C planes is best. Don’t fl y within six miles of R/C fl ying
fi elds and never fl y near people—especially children who
can wander unpredictably.

Perform a Range Check

As a precaution, an operational ground range test should be

performed before the fi rst fl ight each time out. Performing a
range test is a good way to detect problems that could cause
loss of control such as low batteries, defective or damaged
radio components or radio interference. This usually requires
an assistant and should be done at the actual fl ying site you
will be using.

First, turn on the transmitter. Then, install the fully-charged
battery into the fuselage and hold it in place with the hook­and-loop strap. Connect the battery and install the cowl top.

Remember, use care not to “bump” the throttle stick.
Otherwise the propeller will turn possibly causing
damage or injury.

With the antenna on the transmitter collapsed (not extended),
begin walking away from the model operating the controls in
a predictable pattern (for example; up, then down elevator.
Right, then left aileron. Right, then left rudder). While
moving the control surfaces, also vary motor rpm. Have your
assistant alert you if the controls fail to respond or if they
move suddenly or erratically. You should be able to maintain
control up to a distance of approximately 100’ [30m].

If the controls respond erratically or if anything else seems
wrong, make certain all the servo wires are securely
connected to the receiver and that the transmitter and receiver
batteries are fully charged. If you cannot fi nd a mechanical
problem with the model it is slightly possible that there is radio
interference somewhere in the area. One option would be to
try another range check at an alternate fl ying site.

To avoid an unexpected dead-stick landing on your fi rst fl ight,

set your alarm or timer to a conservative 4 minutes. When
the alarm sounds you can either land your model or, if you
are an experienced pilot, you may continue to fl y–planning
for a dead-stick landing to see just how long the motor will
run. Circle the plane upwind of the landing area until the
motor quits. Note the run time, then land.

When you learn how much fl ight time you are getting you
can adjust your timer accordingly. Always be conservative so
the motor won’t quit unexpectedly and you will have enough
battery to land under power.

Takeoff

Until you have become comfortable with fl ying your
Cessna 350 Corvalis, do not fl y if the wind speed is
greater than 10 mph [16 km/hr].

One fi nal check before takeoff: always double-check
the fl ight control response to your inputs from the
transmitter before every fl ight. Be certain the ailerons,

elevator and rudder respond correctly and that none of the
controls have inadvertently become reversed.

Don’t forget to fully extend the transmitter antenna.

Place the model on your “runway” with the nose pointing into
the wind—this will reduce the ground speed that must be
reached and automatically provide “heading assist,” making
steering and takeoff easier. Slowly advance the throttle,
adding rudder correction as needed to keep the model rolling
straight. When the plane becomes “light” continue to apply
throttle until you are at full-power—all this will happen in a
few seconds. When suffi cient liftoff speed has been reached
gradually apply “up” elevator, allowing the model to leave the
ground. Do not “yank” up on the stick—rather, be smooth
and allow the plane to establish a gentle climb.

Once you have reached a safe fl ying speed at a comfortable
altitude (approximately 50’ [15m]), work the controls as
necessary to establish a gentle turn away from the runway.

Flying

Landing

One thing to remember is that, when the plane is fl ying away
from you, moving the aileron stick to the right will make
the plane bank to your right. However, when the model is
fl ying toward you, moving the aileron stick to the right will
make the plane move to your left. Of course, the plane is
still responding the same way; it’s just that your orientation
has reversed. This must be kept in mind while learning to
fl y (and is also a good reason to take fl ight lessons from an
experienced pilot!).

To establish a turn, “up” elevator (pulling back on the stick) is

usually required along with aileron input to get the model into
a bank. To stop the turn, apply a small amount of opposite
aileron.

Once you get the plane into the air and have climbed to a
comfortable altitude, the fi rst “order of business” will be to

“trim” the model for straight-and-level fl ight. The model fl ies

best at approximately 3/4-throttle. Adjust the trims on the
transmitter to make minor control surface adjustments as
necessary until the plane will fl y straight without any control
inputs. Often, your assistant can reach over and adjust the
trims for you.

Remember to keep the model high enough to give yourself
time to make corrections, but don’t let it get too far away.
Otherwise, it will be diffi cult to see its attitude and which way
it is going.

To land, fl y down-wind past the landing area. Gently turn into

the wind and reduce the throttle so that the airplane initiates
a descending glide path. If necessary, add power to extend
the glide path to reach the runway. As the model approaches
and loses altitude, gradually and proportionally, add “up”
elevator to control the glide path and altitude. Continue to
apply elevator until the model touches down at which time
you should be holding full, or nearly full up elevator. This will
cause the airplane to slow and settle to the ground.

Caution: If, during a rough landing, the propeller
becomes jammed and cannot rotate, the battery and
speed control will become very hot. Immediately
move the throttle down to stop the motor. If you fail
to do this, the motor, speed control and/or battery will
be damaged.

After Flight

Disconnect the battery and remove it from the airplane,
then turn off the transmitter. Allow the battery to cool before
recharging, or allow the motor to cool before installing
another battery for the next fl ight. Inspect the airplane to
make sure nothing has become loose or damaged.

One fi nal check before landing: see how the model will react
when it’s time to land and you cut the power. To do this,
while still at altitude, cut the motor power. The model should
establish a gentle, downward glide path. This is how the
model will react when it’s actually time to land. Add power
and climb back up to your original altitude.

Practice a few of these “climb and glides” to judge how far
out you will need to be when its time to land.

ElectriFly

Like the popular original Triton charger, the Triton2 offers
easy programming. But the adjustable charge current
has been increased from 5.0A maximum to 7.0A, and
the Triton2 can handle LiPo packs with up to 5 cells in
series. A cool blue backlight on the 2 x 16 LCD screen
makes for easier reading in any conditions, and the
rotating dial has been raised for enhanced feel and more
precise fi ngertip control. The Triton2 is more versatile
too: you get alligator clips that mate onto the banana
plugs, for quick connection to 12V batteries or power
supplies. You'll still be able to charge 1-4 cell lithium­ion and lithium-polymer batteries, and peak 1-24 cell
NiCd and NiMH packs at rates you set to peak detection
values you choose - before discharging them at custom
rates and then repeating the cycle up to 10 times.
