Walkera 4F200 discussion/review

 
First Impression

The new Walkera 4F200 is my first flybarless helicopter with 3-axis-gyro system of the Walkera range. At first glance, it is evident that no short cuts were taken with the materials used in the construction of the Walkera 4F200. The helicopter really looks good, and the supplied top of the range Walkera WK-2801PRO transmitter is an extra bonus. I'm very impressed...

 
Technical and Designing Review

The Walkera 4F200 comes standard with three carbon fiber main rotor blades. The rotor head, blade holders and swash are all metal. All three feathering shafts runs on one ball bearing each that ensures for smooth pitch changes. I'm very impressed with the construction of the main frame. The main frame consists out of two glass fiber side plates, glass fiber battery tray, glass fiber landing skid support plate, tail boom holder, metal spacers and tree metal bearing blocks for the main shaft and tail belt gear. All parts screwed together, gives the Walkera 4F200 a solid main frame.

The 7.4V 1500 mAh/20C LiPo battery is situated in the nose of the helicopter, and is secured in position on the battery tray with the supplied hook and loop Velcro strap. The LiPo battery position gives the Walkera 4F200 a perfect CG, and there is no need to move the battery forward or backwards. All three swash servos are neatly tucked away inside the main frame for optimal swash movements. The main gear is driven by the powerful   WK-WS-21-004 Walkera brushless motor through a 17 tooth metal pinion gear, and gives the main rotor head plenty of torque to cope with 3D maneuvers.

The 20Amp WK-WST-20A-2  Walkera ESC is situated on the side of the main frame just below the main gear. What I like about the Walkera 4F200 is its strong landing skids. They are made from strong plastic and aluminum tubing. The Walkera 4F200 utilizes a tree axis gyro system that stabilizes the helicopter in the rolling, pitching and yawing axis. The tree axis gyro system is incorporated into the 2.4 GHz receiver, and is situated on top of the tail boom-mounting block. All three gyro axis sensitivity can be adjusted on the receiver to suite your flying skills.

A fast digital tail servo ensures for fast and crisp rudder responses, and is situated on the tail boom. Two carbon tail boom struts gives the aluminum tail boom extra support and strength. The Walkera 4F200 is equipped with a tree bladed belt driven metal tail rotor system. Each tail rotor feathering shaft runs on one ball bearing each. Tail rotor pitch changes are very smooth and effortless. The horizontal and vertical stabilizer fins are laser cut out of glass fiber. The high quality plastic canopy is easy removable for battery changes. Two canopy nuts secures the canopy firmly to the main frame, and won't come lose during flight.

The included Walkera WK-2801PRO 2.4 GHz transmitter has an eight model memory, and is programmable to fly helicopters or planes. I found the WK-2801PRO transmitter to be very user friendly. Programming and setup is a breeze with the help of the transmitter manual. Eight AA batteries are needed to operate the transmitter. It would have been nice if Walkera included a rechargeable transmitter battery pack and charger with the WK-2801PRO transmitter.

Overall I'm very impressed with the Walkera 4F200 construction. Walkera is just getting better and better with their new helicopter designs. Great job...

Walkera 4F200 Setup

The Walkera 4F200 setup is done at the factory by professional technicians, so there is no setup to be done. It is just good practice to do an overall pre-flight check before your first flight. If you accidentally erase the Walkera 4F200 model memory from your 2801PRO transmitter, reprogramming can be done with the supplied Walkera 4F200 programming sheet. Each main rotor blade are balanced and set to track perfectly at the factory.
 

Flying the Walkera 4F200

Read the manual carefully before your first flight. The Walkera 4F200 is designed for intermediate and experienced pilots, and is definitely not a beginner's helicopter. At first I thought that there was something wrong with my helicopter as it was pitching forward and rolling to the right just before lift off. The trick is not to touch the aileron or elevator controls until the helicopter is lifting off into a hover. It seems that the 3-axis gyro system gets a bit confused with cyclic inputs while the helicopter is on the ground.

Once the helicopter is in the air, it is very stable and easy to control. Transition into forward flight is very good, and the tail is solid as you apply power to accelerate forward. Rolling left and right is very responsive, and there is no nose up pitching tendencies when you roll out of a turn. The helicopter flies straight as an arrow. The Walkera 4F200 flies very well with the 3-axis gyro settings set at the factory. For faster or less response, pitching, rolling and tail gyro sensitivity can be adjusted to suit your flying skills.

At first I was a bit sceptic to how well the flybarless 3-axis gyro system will work, but I'm not disappointed. It works flawless in normal and 3D flight. The tail is solid during the whole flight, and won't start to wander as the LiPo battery loses power during flight. My timer on the 2801PRO transmitter is set to eight minutes. Eight minutes flights per 7.4V 1500mAh Li-Po Battery won't put excessive strain and drainage on the LiPo, and will result in longer lifetime. Overall the Walkera 4F200 flies very stable without any bad habits.
