Specification: Brand: Eachine Item: E190S Product size: Rotor diameter:375mm Body length: 415mm Height:118mm Radio Frequency Band: 2.4GHz Remote control distance (m): More than 120 meters Battery:Body:LI-POLY 7.4V(1200mAh) 25C Charging time: about 60 minutes Use time: about 10-12 minutes Function Description: 1 It is scaled down according to the proportion of the U.S. UH-1 helicopter, with high-simulation appearance details and cool lights. 2 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. 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 adopts laser radar + lower visual optical flow positioning and height determination system, which is more stable and more accurate in height 5 It uses 2511 1200KV brushless motor for self-stabilization and co-drive to reduce gear agitation. It has the characteristics of 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. 6 The tail lock motor uses a special 1204 5500KV brushless motor, which is resistant to high temperature, fast responses, stable tail lock, and not easy to damage after long-term work. 7 Using an enlarged 4.3g metal gear servo, it has the characteristics of high torque, fast responses, high precision, and accurate return to the center. The response speed is 60 /0.05ms, which makes the aircraft fly accurately, feel good, and last longer. Using 3 servos, it can fly accurately even if there is a 4-5 level wind outdoors. 8 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. 9 Brand new 8-channel high-precision remote control, 2.4GHZ two-way communication protocol. With 1024-level operation feel, high-definition display, and two-way data transmission, it can provide real-time feedback on important information such as aircraft power, flight speed, flight altitude, flight distance, flight direction, GPS number, etc., effectively improving users' precise control of aircraft. 10 Adopt high-precision CNC rotor head cross plate to optimize structure, reduce weight, and greatly reduce the probability of aircraft damage. 11 The casing adopts hot runner injection molding process, with high simulation details, good elasticity, toughness, and not easy to crash. 12 Standard six-channel remote control, independent potentiometer optimizes the output of the joystick, and the operation is more refined. 13 Professionally customized high-rate lithium polymer 7.4V 1200mah 25C battery, high discharge rate, long service life, flight time of about 9-12 minutes, normal use can reach 500+ cycles. It has functions such as preventing overcharge, over-discharge, and low-power indication, which can more effectively extend the battery life. 14 Intelligent module battery, with charging protection and low power protection function, using the universal TYPE-C plug on the market, charging is more convenient.
