Assembly Manual

2 E-flite Piper Pawnee ARF Assembly Manual
Introduction
The Piper Pawnee entered service in the late 1950s as one of
the first planes to be purpose-built for agricultural spraying and
dusting. While most have been retired from crop-dusting duty,
many are still on the job today towing advertising banners or
serving as towplanes for glider clubs around the world.
E-flite’s Piper Pawnee 15e ARF is a superbly detailed replica
of this aerial workhorse that flies every bit as good as it looks.
Its fuselage and wing outlines are exact-to-scale and perfectly
match the proportions of the full-scale Pawnee. Other realistic
touches include the prepainted fiberglass cowl and belly pan
as well as cockpit instrument gauges and a pilot’s seat. And
like its full-scale inspiration, the Pawnee 15e’s generous wing
area gives it exceptionally forgiving flight characteristics that
are perfect for newer pilots. You can even outfit the Pawnee 15e
with optional flaps and experience exciting short field takeoffs
and landings.
Using the Manual
This manual is divided into sections to help make assembly
easier to understand, and to provide breaks between each
major section. In addition, check boxes have been placed next
to each step to keep track of each step completed. Steps with
a single circle () are performed once, while steps with two
circles () indicate that the step will require repeating, such
as for a right or left wing panel, two servos, etc.
Remember to take your time and follow the directions.

Required Radio Equipment
You will need a minimum 6-channel transmitter (for proper mixing
and dual rate capabilities), crystals, micro receiver, and four mini
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 DSM2®6-channel
full range transmitter and receiver (no servos). If using your own
transmitter, we recommend the JR SPORT™MN48 Mini servos.
If you own the Spektrum DX7 radio, just add the AR7000 DSM2™
7-channel receiver and four of our JR SPORT MN48 Mini servos.

Notes Regarding Servos and ESC
WARNING: Use of servos other than those we recommend may
overload the BEC of the recommended Electronic Speed Control
(ESC). We suggest the use of only the servos we recommend
when utilizing the recommended ESC’s BEC, or the use of a
separate BEC (like the UBEC) or receiver battery pack when
using other servos.
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.
