By comparison, a coaxial-bladed Hirobo XRB Sky Robo is mostly constructed of standard plastics, can only be flown indoors due to its light weight and foam blades, has proprietary onboard electronics and retails for US$80 more than the Blade CP. Stock main rotor blades are constructed of balsa covered by standard model aircraft film and balanced internally with thin, short strips of lead.
It is available under part number EFLH1101 at a cost of US$89.99.Ĭonstruction is entirely of carbon fiber and composites covered by a thin Lexan canopy, firsts for a micro helicopter of this size and price range. An ARF version less electronics was recently introduced for those wishing to do so. E-flite refers to the system as CCPM, or "Cyclic/Collective Pitch Mixing." Standard, discrete micro-helicopter onboard electronics can be fitted. It operates three E-flite S75 high-torque microservos which manipulate a 120-degree swashplate. The four-in-one unit is compatible with other 72 MHz FM transmitters utilizing negative shift deviation, such as Futaba and Hitec. The model is so named because it mixes both collective and pitch via a unique and sophisticated four-in-one onboard module which combines the functions of an electronic speed control, receiver, tail rotor control and piezoelectric gyro. Because of this, the Dragonfly04 utilizes a four-channel radio while the Blade's is a six-channel system. The difference is much more pronounced since the Dragonfly's main head is fixed pitch. Another similar micro-helicopter is the Walkera Dragonfly04. The main difference between the two lies in the canopy design, color and trim as well as a slightly higher retail price because of the Honey Bee's standard lithium polymer battery as opposed to the Blade's nickel metal hydride pack. It is nearly identical to another micro helicopter, the E-Sky Honey Bee. Introduced in 2005, it comes complete with everything necessary for operation except for eight AA alkaline or nickel cadmium batteries for the transmitter. The E-flite™ Blade™ CP is an extremely popular RTF 300-class electric micro-R/C helicopter designed and marketed by E-flite, a division of Horizon Hobby of Champaign, Illinois, USA.
