How to Align a T-Rex 450 V2

The alignment of your T-Rex 450 V2 is important because poor alignment could prevent your T-Rex from lifting off. However, if you think your helicopter is off balance, it is easy to realign your T-Rex. Even if you do not think helicopter is misaligned, you should perform test this every time you fly.

Things You'll Need

Precision Phillips screwdriver
Pencil
Masking tape

Instructions

- 1
  Use a precision Phillips screwdriver to unscrew the screws attaching the tail rotor to the tail. Disconnect the rotor.
- 2
  Slide the tail rotor onto a pencil so that it spins freely. Hold the pencil parallel to the floor and in front of you so that the sharpened tip of the pencil points away from you. Look at the rotor from the side and see whether or not one of the blades dips below the pencil. If neither blade does, set the rotor aside. If one of the blades does dip below the pencil, the rotor needs to be adjusted.

  Stick a small piece of masking tape to the end of the blade that seems higher to adjust the balance of your tail rotor. Continue adjusting until the two blades are balanced on the pencil

  Next, place a one-inch strip of masking tape on the tip of the left-hand rotor of the main blades.
- 5
  Start the helicopter and turn the main rotors with the throttle. Watch the white streak of the masking tape to see whether or not it creates a level line. If the line is not level, turn the helicopter off and adjust the linkage rods attaching the servo to the main rotor. The linkage rods pop off the linkage balls and can be turned to make them longer or shorter. Continue to adjust and test the linkage rods until the white streak is level. Remove the piece of masking tape.
- 6
  Fit the tail rotor onto the tail boom in its original position. Screw the tail back into place using the screws removed earlier.
