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.

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 ( circles (
) indicate that the step will require repeating, such
as for a right or left wing panel, two servos, etc.
) are performed once, while steps with two
Remember to take your time and follow the directions.

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 Brushless ESC with switching BEC you do not need a 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.
