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.

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.

If your ESC is not capable of supporting the current draw of four mini-size servos the speed control may shut down due to high heat.

In order to provide the most reliable product, E-flite recommends the use of a separate BEC (like the Ultimate BEC), or receiver pack and switch to ensure trouble-free operation as follows:

Use the battery and switch harness to power the receiver and servos after disabling the BEC on the ESC (by following the instructions included with the ESC).

4.Usethetwohookandloopstrapsincludedwithyourplanetosecurethebatteryinsidethefuselage.
