Titan Trex 450 RC R/C 2.4G Helicopter 6CH 2.4GHz 3D RTF 80% of the kits components are manufactured from rigid high precision aluminum alloy. The six (6) piece shaft made using CNC technology making each part of the highest precision and quality possible. 2. Using Ball and Hiller two systems mixing control. Through simple system of the Ball control, the power-saving Hiller and CCPM control, you can simultaneously control 3 servo's for AILE, EVLE, PIT. This CCPM control system is great for 3D flying and extending the life cycle of servos. 3. Uses a fly-bar weight to provide a more stable flight and sensitivity. 4. Belt driven rotor, which is easily adjustable for a more stable flight and low noise. 5. Contains 34 precision bearings. 6. Auto-Rotation System and CNC Metal tail unit and tail holder are manufactured from rigid aluminum, giving a greater lifespan and reliability. 7. Equipped with the Titan 6 channel transmitter and including the PIT parameter adjustment.
