The TandemZ is a full three channel, auto stable system with twin propellers and an advanced multi-role set-up that requires skill, brains and determination to master. The TandemZ closely resembles the iconic Sea Knight Helicopter, a vehicle famed for its assault transportation of combat troops and its ability to land on aircraft carriers. The twin rotor system is a striking feature of this unique style of helicopter, which provides greater stability, greater control and added power when airborne. The TandemZ being a full 3 channel radio controlled unit, allows users to control the flight altitude, forwards and backwards movement and the direction of flight. The handheld control unit (which doubles as the charging base for the TandemZ) is more sophisticated than the standard R/C chopper, incorporating controls for Yaw trimming (direction), Pitch trimming (hovering angle), Throttle (altitude), Direction (forward/backward movement) and an additional headlight switch for flying in the dark. With guidance from the instruction booklet and a little practice, users will quickly appreciate the added control that the TandemZ offers and once mastered, can achieve more challenging stunts than ever before.
