PROTECT YOUR MODEL, YOURSELF
& OTHERS...FOLLOW THESE
IMPORTANT SAFETY PRECAUTIONS
1. Your 38% Extra 330S ARF 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 Extra, 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. You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in good condition,
a correctly sized engine, and other components as specifi ed
in this instruction manual. All components must be correctly
installed so that the model operates correctly on the ground
and in the air. You must check the operation of the model and
all components before every fl ight.
5. 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.
6. 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.
7. WARNING: The cowl, wheel pants and landing gear fairings
included in this kit are made of fi berglass, the fi bers of which
may cause eye, skin and respiratory tract irritation. Never
blow into a part (wheel pant, cowl) to remove fi berglass dust,
as the dust will blow back into your eyes. Always wear safety
goggles, a particle mask and rubber gloves when grinding,
drilling and sanding fi berglass parts. Vacuum the parts and
the work area thoroughly after working with fi berglass parts.
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.
Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.
ITEMS REQUIRED FOR COMPLETION
Engine
The 38% Extra was designed for a 150cc engine—the
Desert Aircraft 150cc in specifi c—but the Extra’s size and
weight also make it suitable for any 150cc engine and other
engines down to 120cc. Instructions for installation and
throttle hookup feature the “DA,” so if using a different engine
use the instructions as a guide. The spinner is also drilled to
fi t the DA.
Servos
Following are the number of servos required and the minimum
torque ratings (at 6 Volts) for each:
❏
(4) Aileron servos with a minimum torque of 190 oz-in
each (such as Futaba ® S9155 – FUTM0215)
❏
(3) Rudder servos with a minimum torque of 120 oz-in
each (such as Futaba S9155 – FUTM0215 or Futaba
S9350 – FUTM0235)
❏
(2) Elevator servos with a minimum torque of 300 oz-in
each (such as Futaba S9156 – FUTM0216 or Hobbico ®
CS-170 – HCAM0316) If using Hobbico CS-170 servos,
one (1) servo horn set CS/TS35-59, 63-71 (HCAM1071)
must also be purchased separately for each servo.
❏
(1) Ball bearing, "medium-torque” throttle servo (such as
Futaba S9001 – FUTM0075)
❏
Receiver battery with a minimum capacity of 3000 mAh
(such as HydriMax ™ Ultra 6.0 Volt 4200mAh NiMH –
HCAM6355)
❏
Ignition battery with a minimum capacity of 1000 mAh
(such as HydriMax Ultra 6.0 Volt 2000mAh NiMH –
HCAM6351)
Transmitter and Receiver
A minimum of 5 or 6 channels will be required. All three rudder
servos may be connected to one channel in the receiver via
a servo synchronizer. The aileron servos in one wing should
be connected to one channel and the aileron servos in the
other wing should be connected to another channel. The two
channels for ailerons should be mixed electronically via mixing
in the transmitter. The elevator servos may be connected to
separate channels in the receiver and mixed electronically
through the transmitter, or they can both be connected to a
single channel in the receiver. If using one channel for the
elevators, a servo reverser will also be required to get one
servo to respond in the opposite direction.
