How to Align a T-Rex 450XL RC Helicopter

Many RC enthusiasts consider the radio-controlled (RC) helicopter to be the most difficult vehicle to navigate. While the complexities of the aircraft's controls make it harder to grasp than more simple models, a proper setup could minimize the learning curve as much as possible. Learning how to properly align a T-Rex 450 XL helicopter could mean the difference between a successful flight and an accidental collision with an obstacle or the unforgiving ground.

Instructions

- 1
  Place the fully charged helicopter on a flat, wide-open surface. Choose a location with minimal wind, since this will drastically hinder the alignment procedure.
- 2
  Use the left joystick to increase the throttle until the aircraft lifts off the ground. Allow the helicopter to gain a foot of altitude, then adjust the trim by sliding the scroller located beneath the right joystick. If the helicopter rotates clockwise, click the trim adjuster to the left to offset this rotation; if it spins counterclockwise, move the adjuster to the right. Make minor adjustments until the helicopter flies straight.
- 3
  Land the helicopter by slowly decreasing the thrust with the left joystick. As the helicopter approaches the ground, slightly increase the throttle to reduce the impact of the landing. Lower the throttle joystick to it's idle position, then assess the idle setting of the throttle. If the helicopter blades don't slow down completely, reduce the throttle trim with the adjuster located to adjacent to the left joystick. Continue to reduce the throttle until the rotor ceases to move when the throttle joystick is in its idle position.
