Align Trex Se Setup Guide

Align Trex SE Setup Guide. version 1.0

Although I have successfully flown nitro and electric helis in the past I only recently discovered that my setups were 
never actually correct. The difference in performance of a correctly configured heli and what I thought was correct is 
really amazing. This is not a complete build but information on how to correctly setup your servos, linkage, pitch and 
throttle curve so you have a smooth operating heli. 

The following steps are based on a Trex SE that has been correctly assembled and all components installed. The 
radio used is the Spektrum DX6. These steps are specific to the Spektrum DX6 so please see your manufacturers 
instructions for placing your radio into the correct helicopter mode, in this case CCPM, and other options such as 
servo reversing, gyro gain, etc. 

Radio settings, rates, degrees and any measurements shown in this guide are from 

my working SE. Do not assume that by using the same values you will get the same results. Please verify all your 
settings and general operation of your heli. I will always try to keep this information updated and error free however it 
is your responsibility to make sure your heli is operating correctly.

#1 Radio Setup (Spektrum DX6)

The battery to your helicopter does not need to be connected at this time. 

     

First we will set the radio into Heli Mode. 

     

While pressing up on the scroll and increase buttons, turn the power switch on. You are now in
