INTRODUCTION

Congratulations and thank you for purchasing the
Top Flite Gold Edition P-39 Airacobra. We are sure
you are eager to build and fly your P-39 Airacobra
just as we were eager to build and fly our prototypes.

The nice thing about the Gold Edition P-39 Airacobra is
that although it is a highly detailed scale model with all
the goodies, such as a realistic looking scale outline,
built up tail surfaces, retracts and flaps, it is one of the
few military aircraft that had a tricycle gear
configuration. Those of you who have not yet mastered
airplanes that are tail draggers, will appreciate this
model's great ground handling characteristics.

One last note before you continue: we highly
recommend you get some pictures or a book about
P-39 Airacobras or send for your documentation
package as soon as possible. This way you can
study the drawings and photos to get a feel for how
your P-39 Airacobra should look when you're done.
This will also help you figure out what scale details to
add and decide on a trim scheme.

Well, this should be enough to get your juices
flowing, so get your other projects off your
workbench, say goodbye to your significant other for
a while and...keep reading!

Please inspect all parts carefully before you start
to build! If any parts are missing, broken or
defective, or if you have any questions about
building or flying this model, please call us at
(217) 398-8970 or e-mail us at www.top-flite.com
and we'll be glad to help. If you are calling for
replacement parts, please look up the part
numbers and the kit identification number
(stamped on the end of the carton) and have
them ready when you call.

PRECAUTIONS

1.You must build the plane according to the plan and
instructions. Do not alter or modify the model, as
doing so may result in an unsafe or unflyable model.
In a few cases the plan and instructions may differ
slightly from the photos. In those instances you
should assume the plan and written instructions
are correct
.

2.You must take time to build straight, true
and strong.

3. You must use a proper R/C radio that is in first
class condition, the correct sized engine and correct
components (fuel tank, wheels, etc.) throughout your
building process.

4. You must properly install all R/C and other
components
so that the model operates properly on
the ground and in the air.

5. You must test the operation of the model
before every flight
to insure that all equipment is
operating and you must make certain that the model
has remained structurally sound.

6. If you are not already an experienced R/C pilot,
you must fly the model only with the help of a
competent, experienced R/C pilot.

Remember: Take your time and follow instructions to
end up with a well-built model that is straight and true.

DECISIONS YOU MUST MAKE

ENGINE SELECTION
Recommended engine size:

.61 to .75 cu. in. [10cc to 13cc] 2-stroke
.70 to .91 cu. in. [12cc to 16cc] 4-stroke

Your Top Flite Gold Edition P-39 Airacobra will
perform well with any of the engines within the
recommended range. We flew our prototype with
the O.S.

®

61FX and had more than ample power.

With a larger engine you will most likely find
yourself throttling back to achieve scale-like
speeds for level flight but will have plenty of extra
power to vertically climb away from the pursuing
enemy aircraft.

RETRACTABLE LANDING GEAR
You may build your P-39 Airacobra either with
fixed or retractable landing gear. All the hardware
you need for fixed gear is supplied with this kit. We
do, however, provide detailed instructions on how
to install retractable landing gear available from
Robart. They are pneumatic to simplify installation
and hookup. You may choose to use another type
of retract but it is up to you to make modifications
required to fit them. For Retractable Landing Gear
you will need these items:

❏ 85 degree Main gear #606HD (

ROBQ0006

)

❏ 105 degree Nose gear #TFP39 (

ROBQ1660

)

❏ Robart #188VR Variable rate air control kit

(

ROBQ2302

)

❏ Extra air tubing (

ROBQ2363

)

❏ Robart #164G Hand pump w/gauge (

ROBQ2388

)

❏ Quick disconnects (

ROBQ2395

)

❏ (4) #4 Flat washers (

GPMQ3402

)

❏ Pull-Pull kit (

SULQ3121

)

❏ Main gear strut covers (

ROBQ2703

)

❏ Standard servo to operate air control valve
❏ (4) 3/16" [4.8mm] Wheel collars (

GPMQ4308

)

❏ (2) 3/16" [4.8mm] Adjustable axle (GPMQ4282)

NOTE: We, as the kit manufacturer, provide you with a
top quality kit and great instructions, but ultimately the
quality and flyability of your finished 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.
