challenging 3D aircraft a lot less demanding. Its large
wing area and light wing loading offer very forgiving flight
characteristics, especially in slow flight. It’s also compatible with
a range of motor and propeller sizes so you can fine tune the
power and performance to your skill level. Both the E-flite Power
25 and Power 32 brushless outrunner motors bolt to the firewall
without any modifications. Experienced 3D pilots will appreciate
the uniquely designed, machined aluminum 3D control arms
that can handle the rigors of high-torque mini servos and large
control throws. Sport aerobatics or stick-bending 3D, the Eratix
3D 25e is up for whatever you are.

Required Radio Equipment
You will need a minimum 6-channel transmitter, receiver, and
four mini servos. You can choose to purchase a complete radio
system that includes all of these items or, if you are using an
existing transmitter, just purchase the other required equipment
separately.
Note: We recommend the crystal-free, interference-free
Spektrum™ DX7 2.4GHz DSM2™ 7-channel radio. The
complete system includes standard servos, which are not
required for the Eratix 3D 25e.

Notes Regarding Servos and ESC
WARNING: Depending on what speed control you are using,
if it is not capable of supporting four mini-size servos because
of current draw, the speed control may shut down due to high
heat.
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: When using our recommended E-flite 60A Pro

separate receiver pack as long as you are using our
recommended servos.
Important Servo Note:
If you plan on flying your Eratix 3D 25e to its full
capabilities, we recommend only metal geared servos.
During 3D flight, the large control surfaces will exhibit
large flight loads on the servos. Plastic geared servos
failed during testing and are not recommended for use.
Important Information About Motor
Selection
The Eratix 3D 25e does not include a propeller. We are
recommending the Power 25 or Power 32 outrunner motors.
The motor systems listed will provide you with excellent
aerobatic power for sport and/or artistic aerobatic pilots.

Notes 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.
