Final Check - Align Trex SE Setup Manual

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.
Hook up your motor leads to the ESC.
Turn on your transmitter and set the collective/throttle (left stick) at full low.
Connect a fully charged battery to your ESC.
Allow the heli to sit still while everything initializes. You will hear a series of beeps and the motor may bump
slightly during the beeps.
After everything has initialized you may slowly increase collective/throttle (left stick) at which time the rotors
should start to turn. (clockwise looking from top).
If you hear the motor turning but the rotor does not, reduce collective to full low.
Increase collective again and the rotor should turn in the clockwise direction.

#6 Final Check

Before attempting hover or flight there are several areas to check and are not limited to the following.
Binding
Clearance
Gear Mesh (the amount of play between the main and pinion gear)

The motor may be reversed so swap any two motor leads to reverse operation.
If the rotor fails to turn again and you hear the motor there are a couple things that should be
checked.
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.
Disconnect your motor leads for safety
Give the heli full cyclic by moving the cyclic (right stick to the top right corner).
Spin the blades with your hand and watch and listen for any binding or rubbing.
TIP: watch the swashplate and if it moves or appears to bump then something is
probably hitting somewhere.
Continue doing this on the remaining three corners of the cyclic control (full top left, bottom
left, bottom right). The corners should be the full extent of motion but to be safe check the
entire range by moving the cyclic stick in a complete circle, or in the case of the DX6 a
square.
Move all servos to their fullest extent in both directions.
Make sure servo arms do not touch, rub or extend into any moving part like the main
gear.
Finding the right gear mesh is very important. Although the gear appears round, it will likely
be slightly oval (egg shaped) having one more high spots. Due to this it will be necessary to
have tight mess on the high sides of the gear in order to get correct mesh on the low. If you
were lucky enough to get a truly round gear then you can have correct mesh all the way
around. Clone that gear and send it to me.
Unfortunately its really not possible to visually verify mesh while the gears are on the
heli so we use our thumb to rock the gear and feel the mesh. Look at the images
below to see what you are feeling for.
If the above checks out then your pinion gear is either loose or not
making contact with the main gear.
