Walkera Dragonfly V370D01 4CH FP CNC Metal Flybarless RC Helicopter RTF 2.4Ghz w/ WK-2403 Tx, 3 Axis Gyro Stablizing Sys.

This new 4Ch fixed pitch should be the first helicopter you should fly if you are new to RC hobby circle! The new helicopter, equipped with 3-Axis Gyro with Auto Stabilizing Technology (AST), and by the meaning of 3-Axis Gyro, it acts like a Co-Pilot for the helicopter, it helps you to keep the helicopter's stability, isn't it amazing? This V370D01 is specially made for beginners, and for those who can manage flying a coaxial helicopter should also fly it well.

What exactly a 3-Axis Gyro do?

3-Axis Gyro means it can sense X, Y and Z axis moments, that means body leaning forward / backward, body rolling left / right, tail drifting CW / CWW, it will constantly monitoring any off-balance in all directions, then it will give signals to all CCPM servos and Rudder servo to balance the helicopter, it works constantly and unless you have the helicopter drifts too much, you will not even notice the system exists. The following diagram will simply tell you more on how it works.

What is flybarless system?

Paddles are doubtless an important component in RC helicopters for a long time, it the aircraft stable. Recently, 3-Axis Gyroscope has been introduced to RC helicopters and this is how Flybarless System has born. The NEW Flybarless System takes away the paddles and flybar, leaving the stabilizing job completely to the high tech 3D Gyroscope. Proven by Helicopter World Champion, result is 100% positive. Without the weight of the flybar and paddles, the helicopter now moves in higher speed, and saves almost 30% energy. Also, less parts means less repair and maintenance!

Features for the NEW Flybarless system:

• Compact flybarless structure, which features lower power loss, remarkably improves efficiency.
• 3-axis gyroscopic flybarless system to simulate the stability of mechanical flybar system, yet at the same time achieving agile 3D performance.
• Flybarless system dramatically improves power output and efficiency, resulting in reduced fuel or electricity consumption.
• Highly sensitive gyroscopic sensors combined with advanced control detection routine providing higher hovering and aerobatic stability than other flybarless system.
• The design of flybarless balance characterizes low power loss and great efficiency improvement.
• Three-Axis-Gyro in receiver control makes the flybarless balance system automatically amend the flight status and provide favorable safety for the beginners.
• Adopting high efficient shaft driven system presents green, environmental friendly and safety concept.

The simple mechanism is another characteristics that shows it is how suitable for beginners. It has simple structure, just a few parts and everyone understand how it works! This also means easy repairing, you won't find fancy electronic settings nor difficult physics theory. Simply, just replace the broken parts with another one, then you can start flying it again!

A few points best summerize the features for V370D01:

• Simplicity of the helicopter off the scale. A compact helicopter includes all components it needs to fly.
• Three-Axis-Gyro in receiver control makes the flybarless balance system automatically amend the flight status and provide favorable safety for the beginners. You will find a great different without this little gyro!
• Super easy to repair, even for beginners
• Middle size, with all up weight 267g, convenient to fly outdoor and capable of flying indoor.
• The flying time can reach 7-9 minutes for one battery cycle with the high performance brush motor and the high capacity Lipo battery .
• 2.4Ghz Radio System, the WK-2403 provides you with almost zero interference for signal transmission.
• Cool Appearance, looks professional. You are a step nearer now!

Highlight features of the Walkera WK-2403:

• The WK-2403 adopts frequency-hopping spread spectrum 2.4G technology and features automatic code pairing and ID assignment.
• Graphic display menu is simple to understand and to set.
• The appearance design accords with ergonomics and features easy holding. The LCD screen with backlight and graphic interface looks more personalized.
• Both the length and tension of the stick can be adjustable. It is convenient to freely switch among the 4 stick modes.
• New! Throttle Limit. This limits the throttle to 30-80%, which limits the height.
• New! Dual Rate Switch. This limits the servo travel to 50% for more stable flight
