It is equipped with High Performance Brushless Motor, Electronic Speed Controller, High Speed Tail Motor, Redesigned Body Frame, 2.4GHz advanced radio system, Metal Swashplate, Metal Blade Clamp and Metal Rotor Head.

This is the latest 2.4Ghz Walkera 4-3, the super micro radio controlled helicopter, come in Ready-To-Fly package with all the necessary items inside. It is stable and easy to fly, you can learn how to fly it in 1-2 days. Its overall length is only 185mm controlled by 2 x 3.5g only micro servos. With compact 90 degree swash plate structure, the servo and other parts are easy to install. The tiny 4-in-1 controller is integrated with Receiver, ESC, Gyro and Mixer with high sensitivity and strong resistance to interference. The 4-channels 2.4Ghz transmitter with over 100+ channels allows you to find different 2.4Ghz at the same time without collision, also the power indication avoids the crash caused by lack of transmitter electricity.

Walkera HM 4-3B Features
The 4#3 comes with a small and simple layout that?s very clean and robust. Everything flows really well, as the writing is organized and all the components are laid out with room to spare.

  • Super mini servo (3g) is prompt and accurate in reaction;
  • One cell Li-Po battery at 3.7V 400mAh offers 8- to 10-minute flight after fully charged;
  • 4-channel transmitter with visible power indicator can avoid helicopter losing control due to the shortage of battery power, and support you to fly without any worry.

ROTOR BLADE
The main rotor blades are conventional plastic blades commonly found in fixed pitch designs, it is designed with a predetermined angle of attack and both blades are attached together in a single assembly. The blades also have a unique color scheme (which is breath of fresh air) and even contains a well- written warning.

COMPONENT LAYOUT
The 4#3 uses two small servos that mount to both sides of the frame with all aluminum tabs directly below the swash. The motor is mounted inverted, directly in front of the aluminum swash and on the frame itself. There is a designated battery tray that is mounted to the main frame which snugly holds the battery. The receiver mounts on a tray in the very front which screws to the frame.

LANDING GEAR
The one- piece landing gear consists of a very thin wire- like metal materials that runs through a small top on the bottom of the frame. It can also be disconnected from the loops in the back.

HEADBLOCK
The aluminum head block a small o- ring type damping system due to the over lapping style plastic blades, and it is clamped to the main shaft. It also utilizes a swiveling fly bar that is attached with small brass inserts.

CANOPY
The plastic canopy comes pre- painted with a black windshield and a red and black color scheme. It has two slits in the bottom where the landing gear slides in, and it utilizes two grommets on the back that attach to a single plastic rod.

SWASHPLATE
The all aluminum swash plates are bearing supported and because of the heli?s fixed ? pitch design it sits permanently in the same position. It is directly connected to only two servos with the use of integrated balls. It uses a anti rotation pin that slides freely in the anti rotation bracket.

DESIGN
The frame is a simple, small one piece plastic design. Both the plastic battery mount and front receiver tray both to it.

MOTOR MOUNT
The motor is mounted directly in front of the main gear in an inverted position. It is bolted to the frame itself by way of two self- tapping screws.

PINION
The pinion is made of plastic and meshes directly to the main gear.

MAIN GEAR
The black plastic main gear is retained with a very small Jesus pin and has large cutouts in order to reduce its weight.

TAIL DRIVE
The tail is a motor driven so there isn?t any use of a conventional belt drive, pulley systems, etc. However, the motor in the tail does directly spin a small gear, which in turn meshes with a gear attached to the tail blades for tail control.

BOOM
The carbon boom requires no boom supports because of its light weight and measures in at 105 mm in length.

?OVERALL, 4#3 PROVED TO BE A DURABLE AND RELIABLE HELICOPTER. AFTER MANY FLIGHTS AND A FAIR AMOUNT OF INDOOR CRASHES [IT?S BOUND TO HAPPEN] , THE HELI SHOWED NO SIGNS OF DAMAGE AND KEPT FLYING THE WAY IT SHOULD.?
