DECISIONS YOU MUST MAKE
5. You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air.
6. You must check the operation of the model before
every
fl ight
to insure that all equipment is operating and that the model has
remained structurally sound. Be sure to check clevises or other
connectors often and replace them if they show any signs of
wear or fatigue.
7. 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.
8. 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.

WARNING:
The cowl and wheel pants 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 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.
DECISIONS YOU MUST MAKE ––––––––
This is a partial list of items required to fi nish the Razor 3D ARF
that may require planning or decision making before starting to
build. Order numbers are provided in parentheses.
RADIO EQUIPMENT
The Razor 3D ARF requires a minimum 4-channel radio system
with four 44 oz.-in. [3.2 kg-cm] minimum standard servos. If
you are installing a glow engine, an additional standard servo
is required for the throttle. For maximum performance, we
recommend installing Tower Hobbies TS-160 digital servos
for the control surfaces.
In addition, two 12" [305mm] servo extensions are required
for the aileron servos and two 24" [610mm] servo extensions
are required for the elevator and rudder servos. If you are
using a radio system that does not support mixing functions, a
Y-harness will also be required to connect the aileron servos to
the receiver.
A charge jack receptacle is optional, but is useful for recharging
and checking the voltage of the receiver pack without removing
the canopy hatch. Recommended part numbers for the radio
components are provided below:
