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
o
now in System Mode.
Press scroll until TYP is displayed.
o
Press increase and select HE.
o
Press scroll until GER is displayed.
o
Press increase and select A
o
To save either turn the radio off or press scroll and increase at the same time.

•
Now we will set options in Function Mode.
Turn the radio on if it is not already on.
o
Press scroll and increase. You are now in function mode.

- Page 3 addition using that much cyclic may cause bogging. Shoot for 6 degrees total and then advance to around 9 degrees total. The radio settings should now be very close to final with the exception of possible servo reversing, subtrims and gyro gain adjustments. #2 Servo mounting, connections, direction and centering Servo mounting may vary slightly but I found the following offers good alignment.
- Page 4 Set Aileron D/R Switch to 1. Turn on the transmitter. Make sure all of your trims are at 0. Set your collective (left stick) to center. It should be in the same position as the right stick. Disconnect your motor from the Electronic Speed Control (ESC) and plug a fully charged battery pack into the ESC.
- Page 5 Aileron D/R switch to one and all other switches at 0. Motor disconnnected for safety. Connect battery to ESC and wait for Gyro to initialize. All servo arms should still be centered. Extend your main blades and make sure the flybar and the blades are level. Examine the image below and compare to your head linkage.
- Page 6 § If you are unable to reach +10 degrees before the surfaces touch, there is a problem with linkage elsewhere. Go back and recheck your linkage. Figure I Figure J • Now we check the negative pitch. Set your pitch guage to -10 Place it on one of the main blades.

- Page 8 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 9 § Hold the main rotor with one hand and attempt to turn the main gear clockwise. It should not turn in this direction however it will turn counter clockwise. § If the gear turns in both directions it could be a bad one way bearing or your, a missing or sheared main gear bolt or metal main housing bolt.
