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

- Page 2 Align Trex Se Setup Guide System Mode. Press scroll until TYP is displayed. Press increase and select HE. Press scroll until GER is displayed. Press increase and select A To save either turn the radio off or press scroll and increase at the same time.
- Page 3 Align Trex Se Setup Guide CP2 and CP3 can be increased if you are experienced or after you become comfortable with your heli. The transmitters default setting of 60% will give you about 12 degrees total cyclic travel, [ -, + 6 degrees]. At this high setting the mechanics are very near binding.
- Page 4 Align Trex Se Setup Guide Ch. 2 is mounted from the inside of the right frame. Figure C Servo Centering and Direction can now be checked. Remove all servo arms from the servos. Set Aileron D/R Switch to 1. Turn on the transmitter.
- Page 5 This tool is used to measure the pitch angle of the main rotor blades in relation to the flybar. The Align Pitch Guage (figure D) works very well and is specifically for smaller electric helis. If you do not have a pitch guage you should not continue until you do or have some other manner of determining the pitch.
- Page 6 Align Trex Se Setup Guide Figure E Figure G Setting 0 pitch Check that transmitter sticks are at center. Set your pitch guage to 0 and place it on one of the main blades. Hold the flybar and blades level by lifting on the guage.
- Page 7 Align Trex Se Setup Guide Push the collective (left stick) all the way up. Level the blades and flybar by lifting on the guage. The top of the guage and flybar should be parallel or very close. (figure I below) If more pitch is needed to get +10 degrees we will need to access the Function Mode on the transmitter.
- Page 8 Align Trex Se Setup Guide igure K Figure L #4 Setting up the tail rotor, tail rotor servo and gyro Tail servo setup Turn the radio on if not already on. Set the Aileron D/R Switch to 0. The servo should be centered from the previous steps. If it is not you need to go back to the centering section and do this servo again.
- Page 9 Align Trex Se Setup Guide Figure M Figure N Verify Gyro Direction Examine the diagram below and follow these instructions Hold the heli up at the main rotor button with your right hand. (figure O) Use your left hand to push the tail away from you.
- Page 10 Align Trex Se Setup Guide Figure O Setting Tail Rotor Servo Travel Use the rudder stick (left stick) and give full left rudder. Listen for binding and check clearance. (figure P) If you hear binding or see that there is zero clearance, reduce the gyro travel limit on the gyro until you have some clearance.
- Page 11 Align Trex Se Setup Guide #5 Verify throttle operation Your ESC should be plugged into channel 1. Although the ESC may have safety measures to guard against accidental motor starts you should always be cautious. Verify that all switches are set to 0.
- Page 12 Align Trex Se Setup Guide If you get the mesh at the high side to where there is no gap, then your low side mesh should be correct. If its not then your gear is seriously out of round and probably not suitable to use.
