Congratulations on your purchase of the Extra
330ARF. This is a very unique dual-purpose air-
craft, capable of flying any FAI pattern
sequence with ease, while exhibiting remark-
able 3-D capabilities. Every effort has been
made to produce a lightweight, straight, easy to
assemble aircraft. Because of its oversize con-
trol surfaces which are double beveled to allow
for extreme throws, great care must be taken in
the set-up and flying of this airplane. Quality
hardware components have been provided to
allow for 3D set-up while maintaining adequate
mechanical advantage to eliminate flutter. It is
you responsibility as an advanced pilot to fly the
aircraft in an intelligent manner. THROTTLE
MANAGEMENT IS A MUST!!!!!!! Carl
Goldberg Products has flown the Extra 330ARF
through a very rigorous flight-testing schedule
and have stressed the airframe beyond all prac-
tical parameters without a single failure. Carl
Goldberg Products will NOT warrant the Extra
330ARF against flutter due to improper set-up
or excessive speed maneuvers. having said
that, we believe you will find the Extra 330ARF
to be one of the most responsive, in-the-grove
aircraft on the market. Just remember to use
common sense when flying this high perform-
ance machine.
We are very proud of the construction of the
Extra 330ARF and all of our other ARF aircraft.
Each aircraft is jig built to insure a straight true
airframe. Every effort is made to build as light an
aircraft as possible. As with any professional
builder, glue is used sparingly. Please take a
moment during assembly and run a bead of
CA or aliphatic resin into the high stress
joints that you can reach such as the landing
gear plate, servo mounting trays, wing hold
down blocks, etc. Also, during the course of
shipping from the manufacturer to our facility in
the United States, it is not uncommon for the air-
craft to experience several changes in climate.
This may cause the iron-on covering to develop
wrinkles. This is not a fault of the manufacturer.
Please take a few minutes with your heating iron
and heat gun to iron down the seams and re-
shrink the covering where needed. The results
will be a beautiful aircraft with a breathtaking fin-
ish that you will be proud to display at your flying
club.
Before beginning assembly of your Extra
330ARF, we highly recommend that you study
this manual in its entirety. You should begin
planning your radio installation based on your
choice of engine and equipment from the begin-
ning.
Because the Extra 330ARF is intended for
those with some degree of modeling experi-
ence, every minute detail will not be covered.
This is not a basic trainer. Assembly of this air-
craft will be easy for the experienced modeler,
and by following the instructions within this
manual and using the skills you’ve gained dur-
ing your modeling career you will be able to pro-
duce a first class aircraft.
