The most beautiful RC helicopter I’ve seen must be Walkera 4F200LM! Firstly I’d like present a whole-frame picture for you to have a closer look!
Walkera 4F200LMYes! This is the first as well as the only tri-blade helicopter provided by Walkera. Pilots who have experienced Walkera 4F200LM all speak highly of it! The special model is a collective pitch helicopter. And it provides both blue and white versions!

Measured 448mm in overall length, the helicopter only weighs 410g with everything included. It is compact and concise structure that enables Walkera 4F200LM to achieve agile and smooth flights. Additionally, the flybarless system can enhance flight efficiency as well as response speed.

CNC machined tri-blade main rotor is composed of metal blade holder, metal rotor head and metal swash-plate, which eases 3D stunts operation. The 3 main blades can change angle to generate more wind for quick moving. And it will move much quicker than normal fixed pitch helicopters.

The tri-blade helicopter is super stable and smooth in normal three-dimensional flights. Let alone, Walkera 4F200LM is capable of hovering, rolling, 360º rotating, flipping, crabbing, pitching, vertical flying and inverted flying. Equipped with a capable transmitter, more amazing flights are allowed.

With integrated 3axis gyro, Walkera 4F200LM can automatically correct the attitude when flying into wrong direction. 3Axis gyro can sense X, Y and Z axis moments, including leaning forward/backward, body rolling left/right, tail drifting CW/CWW. It can constantly monitor any off-balance in all directions, and it can give signal to all CCPM servos and rudder servo to balance the helicopter.

In addition, Walkera 4F200LM adopts translucent canopy made of ABS plastic, which is of great toughness to survive many crashes. I’ve never saw a helicopter so much resemble the bee, especially when flying at very high altitude. The striking canopy to some extents can help pilot identify the flying direction.

All in all, Walkera 4F200LM is the capable kit for relatively experienced pilots. The main blade adopts carbon fiber of great toughness can’t be deformed easily. And the remote distance is about 300m to 500m. Considering its size, the tri-blade helicopter is suited to fly both indoor and outdoor.
