E-flite Piper L-4 Grasshopper ARF Assembly Manual
Recommended Radio Equipment
You will need a minimum of a 4-channel transmitter,
receiver and four servos. You can choose to purchase
a complete radio system. If you are using an
existing transmitter, just purchase the other required
equipment separately. We recommend the crystal-
free, interference-free Spektrum
™
DX6i 2.4GHz DSM
®
6-channel system. If using your own transmitter, we
recommend using four 6.0-Gram Super Sub-Micro
servos from Spektrum.
If you own a Spektrum radio, just add an AR6300
DSM2
™
receiver and four 6.0-Gram Super Sub-Micro
servos. The SPMAR6300F flight pack works perfectly
for this application. We show the installation of the
AR6300 receiver in the manual.

Note on Lithium Polymer Batteries
Lithium Polymer batteries are significantly
more volatile than alkaline or Ni-Cd/
Ni-MH batteries used in RC applications.
All manufacturer’s instructions and warnings
must be followed closely. Mishandling of
Li-Po batteries can result in fire. Always
follow the manufacturer’s instructions when
disposing of Lithium Polymer batteries.
Warning
An RC aircraft is not a toy! If misused, it can cause
serious bodily harm and damage to property. Fly
only in open areas, preferably at AMA (Academy of
Model Aeronautics) approved flying sites, following all
instructions included with your radio.
Keep loose items that can get entangled in the
propeller away from the prop, including loose clothing,
or other objects such as pencils and screwdrivers.
Especially keep your hands away from the propeller.
Covering Warning
The Piper L-4 Grasshopper is built very light to achieve
the best flight performance possible. When using an
iron or heat gun to shrink the covering or to tighten
up any wrinkles, it is very important that care is
taken not to warp any of the surfaces. It is possible to
induce warps into the surfaces during this procedure.
We suggest taking your time and care to make sure
that no warps are caused as this will affect the flight
performance of the airplane.
During the course of building your model we suggest
that you use a soft base for the building surface.
Such things as a foam stand, large piece of bedding
foam or a thick bath towel will work well and help
protect the model from damage during assembly.
This is not shown in the assembly photographs to
display the detail of the actual building of the model.
Your L-4 Grasshopper has been assembled using the
techniques that keep the weight as low as possible
for the best flight performance. Please handle the
airframe with care during assembly and during
transportation to keep from damaging it accidentally.
