Specification:

Brand: Eachine Item: E250 Product size: Rotor diameter:455mm Body length: 485mm Height:155mm Radio Frequency Band: 2.4GHz Remote control distance (m): More than 300 meters Battery:Body:LI-POLY 11.1V(1800MAH) 30C Charging time: about 90 minutes Use time: about 12 minutes 

Function Description:

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

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

3> The propeller is designed based on the aerodynamic principle 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.

4> It uses 4306 540KV brushless motor for self-stabilization and co-drive to reduce gear agitation, with low noise, high torque, sufficient power and high efficiency. The special high-temperature resistant magnetic steel can withstand 150 degrees high temperature without damage, which increases the service life.

5> The tail lock motor uses a special 1206 5500KV brushless motor, which is high temperature resistant, fast in response speed, stable tail lock, and not easy to damage after long-term work.

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

7> Use a 6-axis gyroscope. It has a stable, fast and accurate flight attitude, especially suitable for beginners.

8> Use 2.4GHZ communication protocol, expandable satellites receiver, support DSMX DSM2 PPM S-BUS format.

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

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

11> Standard six-channel remote control with LCD display and power prompt. It supports digital parameter adjustment and simulator function, and optimizes the output of the joystick for more precise operation.

12> 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.

13> Dedicated 11.1V lithium battery dedicated charger with charging balance and charging stability functions. Package included: RTF: 1 x E250 RC Helicopter 1 x Transmitter 1 x USB Cable 1 x Battery（1,2 or 3 Optional） 4 x Main Propeller 1 x Tail Propeller 1 x Instruction 1 x Aluminum Box
