The Kyosho EP Caliber 400 was born to bring the excitement of 3D acrobatic and stunt flight performance together in a compact sized electric helicopter. The lightweight design starts with the carbon frame and with a scattering of metal parts that contribute to the precision control characteristics; sharp outdoor stunt performance has been achieved. The EP Caliber 400 will surprise intermediate to advanced fliers with its similar flight performance to engine helis. Within its compact frame, the authentic helicopter control mechanisms and R/C system loaded sets a new standard in electric helicopter flight.The Caliber EP 400 uses a belt driven tail system and the deign of the complete tail assembly was engineered with very robust molded plastic and additional support guides to insure the EP Caliber enjoys super smooth tail control and tail performance. Every part of the Caliber EP 400 was well thought of in advance, the skids cover a wide area and the metal head parts insure crisp cyclic control with no play or flex. Carbon Fiber main frame and a two gear system are just some of the advance specification which all come standard in the EP 400. Kyosho has years of experience making R/C Helicopters ( back from the original Kyosho EP produced in the 90?s ) which translates directly into this awesome superior remote control electric Helicopter.
