This body of ESKY F150 is based on that famous helicopter and is a great combination of scale and performance for a Ready-to-Fly. Direct drive tail motor power system for improved power and response. Three-axis gyro flybarless system design brings to more stable flight performance.
The ESKY F150 RTF is the ideal next step for any coaxial heli pilot ready to try single-rotor machines. Its fixed-pitch, simple rotor head and Artificial Stabilization Flybarless System (ASFS) has been specially designed to provide plenty of speed maneuverability while retaining the hands-off stability of a coaxial helicopter.

PS: If the ESKY F150 not easy to be controlled when it takeoff, the reasons maybe as like these: as the system of F150（00442）is 3-Axis Gyro Flybarless, so pls be advised to do these two steps as below: NO.1 pls be confirmed that this helicopter must be flat on the floor or table (must be flat lying) when it takeoff, first unplug the power of the helicopter ( it must be lying flat, not on the hand or hold by hand), then turn on the remote control power switch, wait until it finished the self-test and you can move it (after the self-test passes, the lamp on the circuit board will be lit steady), after complete the boot sequence of the above the helicopter can be the perfect take-off. NO. 2 If the plane needs to re-code, then follow the code program on the instructions to re-code it, particularly notes, my dear friend, your helicopter must be flat on the desk or floor, not arbitrarily placed, because this will directly effect its flight!
