รุ่น:Walkera HM V120DQ02 Helicopter (2.4Ghz Edition)
World's First Palm Size Professional Scale Helicopter
First, I need to explain about the long product name. Factory tends to assume players knew all their product history..... for V120DQ02, "V120" means Flybarless helicopter in 120 size, "DQ" means it's a Scale Fuselage model and "02" means it's a rudder servo controlled tail pitch model. This V120DQ02 is a unique and one of a kind on the market, but you may say there are a lot of palm size helicopter with scale body, why this one is special? I would say because of the advanced electronics, V120DQ02 has a Flybarless Rotor Head to keep the best of a Scale Helicopter should have, and thanks for the Walkera 3-Axis Gyro, the helicopter flies perfectly stable, yet keeping the most realistic appearance. Mass producing a detailed Scale Fuselage and a 3-Axis Gyro involves very difficult technology and production skills, only Walkera has this ability to do it at the moment, so in another word you're buying the most advanced palm size helicopter in the world.
This year every RC hobbyist are talking about Flybarless Helicopter. Now Walkera has developed the Smallest Flybarless CP Helicopter platform in the World - the V120 series. It is a Palm Size Helicopter with Collective Pitch Flybarless Rotor Head. It also has everything you find on a big helicopter, like three CCPM servos, 12000KV Brushless Motor and ESC, a 2.4Ghz All-in-One Receiver, a Gyro (3-Axis) and a Rudder Servo. You may ask "Why Flybarless is good?". Please allow me to explain.
What is 3-Axis Gyro?
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 to much, you will not even notice the system exists, please take a look at the following picture.
It's 100% assembled, you can have it flying in just a few minutes out of the box. Just a quick charge of the battery and you are ready for lift off!
Flybarless Palm Size Helicopter with Scale Fuselage - Only one on the market
Breakthrough in Palm Size Helicopter - They go Flybarless!
3-Axis Gyro and Rudder Servo means good!
Tail rotor is used to generate wind to counter act the main rotor rotation. Precise of tail rotor wind is needed to keep the helicopter heading one direction. We usually have two ways in generating the precise of wind from the tail rotor, one is the Tail Motor, another one is sharing the power from the Main Motor by a tail drive shaft. Tail Motor is usually slower, it can't keep up the main motor's speed and causing the tail to drift while heli is going up and going down, usually low price model and small scale helis use a tail motor. The best solution is to have a Gyro and Rudder Servo. By changing the Tail Rotor blade pitch, you can adjust the amount of wind generating to keep the heli in one heading, to do this, you need a good performance gyro constantly monitoring the heli heading and give correction to rudder servo, then it will push the tail rotor pitch. You will not imagine how quick it worked during the flight, but it is the heart and soul for any RC helicopter.
Tail Rotor and Tail Pitch Mechanism
Shaft driven tail rotor provides smoother and more precise power delivery.
Aluminum Flybarless CCPM and Swashplate Design
Using the most common swashplate design in recent days, the main advantage of Flybarless CCPM swashplate design is that it has much less parts than ordinary RC Helis, less complicated to assemble and repair and because of the swashplate was supported by 3 servos, it can distributes the forces over all 3 servos, leading to less workload on the servos.
12000KV Out-Runner Motor and 20A Brushless Speed Controller
Great power to compensate the extra scale fuselage weight.
Special designed Main Gear
Integrated with Tail Shaft Gear, easy repair and less maintenance.
The New WK2603 6-Channel Digital Transmitter
Thanks for the success of the top of the line WK2801 transmitter, Walkera used the same appearance and make the new WK2603 6-Channel LCD display, 2.4Ghz Digital Transmitter.
