Function Description:

1> It is scaled down according to the 32:1 ratio of the AH-64D Apache attack helicopter of Boeing Company of the United States, with high-simulation appearance details, cool lights and shock-absorbing landing gear. 

2> The new optimization and upgrade is more realistic, with a new paint job, and arms racks, rocket launchers, missiles, airborne Gatling guns, aerial refueling pipes, etc. The tail rotor adopts a high-efficiency four-blade propeller, which is more efficient, quieter and more simulated. 

3> It adopts a flybarless design, a dual-axis co-drive motor, and an electronic stabilization system, which makes the feel more precise, the flight more stable, and the optimized structure reduces the chance of damage. 

4> It adopts a laser radar + lower visual optical flow positioning and height determination system, which is more stable and more accurate in height.

5> The propeller is designed based on the principle of aerodynamics to provide strong power and self-stability of the fuselage. It is efficient, power-saving and has a long flight time. The blades are made of nylon + carbon fiber composite materials, which are high in strength, good in toughness, impact-resistant, non-deformable and durables. 

6> Use 4306 540KV brushless motor for self-stabilization and co-drive, reduce gear agitation, low noise, high torque, sufficient power and high efficiency. Special high temperature resistant magnetic steel can withstand 150 degrees high temperature without damage, and increase service life. 

7> The tail lock motor uses a special 1206 5500KV brushless motor, which has the characteristics of high temperature resistance, fast responses speed, stable tail lock, and long-term work without damage. 

8> Use an enlarged 4.3g metal digital servo, high torque, fast responses, high precision, accurate return to center, and a response speed of 60°/0.05ms, which makes the aircraft fly accurately, feel good, and last longer. 

9> Intelligent flight control, equipped with GPS module, compass module, lower vision module, and air pressure height setting module, with GPS stabilization, lower vision flight, manual self-stabilization mode, and multi-function flight mode, with one-key return, low-power intelligent return, out-of-control return, one-key landing, electronic fence, one-key 8-shaped route flight, one-key circular flight and other safe flight functions. 

10> New 8-channel high-precision remote control, 2.4GHZ two-way communication protocol. With 1024-level operation feel, high-definition display, and two-way return data, it can provide real-time feedback on important information such as aircraft power, flight speed, flight altitude, flight distance, flight direction, and GPS number, effectively improving users' precise control of aircraft 

11> Adopt high-precision CNC rotor head cross plate to optimize structure, reduce weight, and greatly reduce the probability of aircraft damage. 

12> The casing adopts hot runner injection molding process, with high simulation details, good elasticity, toughness, and not easy to crash. 

13> Professionally customized high-rate lithium polymer 11.1V 1800mah 30C battery, high discharge rate and long service life. The flight time is about 10-12 minutes, and it can be used for 500+ cycles under normal use. It has functions such as preventing overcharge, over discharge and low power indication, which can effectively extend the battery life. 

14> Equipped with a dedicated charging stand and a high-precision digital display balance charger. 

15> Can be equipped with 5.8G analog image transmission, with an image transmission distance of 300 meters (user optional) 

16> Supports flight with the open source remote control ELRS protocol receiver. Package included:

1 x F11-S RC Helicopter 1 x Transmitter 1 x USB Cable 1 x Battery（1 or 2 Optional） 4 x Main Propeller 1 x Tail Propeller 1 x Instruction 1 x Aluminum Box
