A great-looking, ready-to-fly small-scale model of the Eurocopter EC135 in a military camouflage livery. This is one of the most popular helicopters being used today by the military, law enforcement agencies, and air ambulances. It is packed full of outstanding features, these make the EC135 not only look great but make it fly brilliantly as well. The full-size EC135 has been developed from the MBB Bo 108 which was the first rotorcraft that could perform aerobatic maneuvers such as loops and rolls due to its innovative rigid rotor system. The other stand-out feature of the EC135 is the "Fenestron" tail-rotor system that is more efficient, has greater controllability, and also offers more protection to the tail system than conventional tail blades.

Features of the EC135 include a 4-blade flybarless rotor head, a 6-axis gyro, and a barometric altitude hold. This gives the EC135 incredible stability making it perfect for beginners, and it's also perfect for the more experienced pilots. The included 2.4GHz transmitter gives you full control of the helicopter, it allows you to climb or descend, fly backwards, forwards, fly left and right, and rotate both ways around its axis. The new style V2 transmitter also includes a one-key 3D feature making for even more fun flying, and a 3-step flight mode button.

A great-looking, ready-to-fly small-scale model of the Eurocopter H145 which is the later version of the impressive Eurocopter EC135. The H145 is a slightly larger version of the EC135 and is gradually superseding the EC135 with the military, law enforcement agencies, and air ambulances. The original EC135 was developed from the MBB Bo 108 which was the first rotorcraft to have a 4-blade rigid rotor system, the H145 has gone even further with having a 5-blade main rotor system. The other stand-out feature of the H145 is the "Fenestron" tail-rotor system that is more efficient, has greater controllability, and also offers more protection to the tail system than conventional tail blades.
