Esky Honey Bee King

The Esky Honey Bee King is a small electric helicopter with collective pitch. It is equipped with a brushed motor and rate mode gyro. It is available ready to fly and almost ready to fly.


The King comes in a number of variations

  • King
The original version, with a shaft driven tail; discontinued.
  • King 2
A revised version with a belt-driven tail.
  • King 2 Carbon
An upgraded version of the King 2 with carbon fibre main frames, alloy head and tail, carbon main blades, and brushless motor.
  • King 3
New model, essentially a restyled King 2 with a brushless motor, heading hold gyro, and a different canopy design.

Known issues

The stock brushed motor has poor life, sometimes only lasting a few flights. It can be helped by removing the carbon brushes and cleaning them and the commutator. The brushed motor has been known to get hot enough to start fires.

The idle up mode switch on the top left of the stock transmitter will cause a dangerous situation if accidentally engaged, instantly applying full power to the motor whatever the collective position. As it is engaged by pulling it forwards, it can be engaged accidentally by putting the transmitter down on an uneven surface.

The diagram in the manual showing how the tail belt drives the tail rotor is wrong. The tail belt should be twisted so that rotating the main rotor (clockwise) causes the tail blades to come up towards the front of the heli (so counterclockwise when viewed from the helicopter's right hand side (the same side the tail rotor is on)).

The tail belt on the King 2 has a habit of coming off the guide rollers and then off the drive gear. Some people make a small guide to prevent this.

Some people find that the tail rotor has poor control authority. There is an upgraded tail belt drive gear with more teeth that increases tail rotor speed, giving better authority. Reducing the 'hover pitch' control can also help.

Another method of improving tail authority is to oval out the holes where the tail pitch slider screws onto to the ball links controlling tail pitch, and ensure that the pitch control is on the "leading edge" of the tail blades. You will need to reconfigure your gyro and rudder channel reversing if this is different to what you currently have.

The frame can flex, allowing the motor pinion to come away from the main gear in high power maneuvers. Some people have reinforced the frame to prevent this.

The King has a very similar head to the Esky Belt CP; in particular the replacement alloy head can be used on either. Some bits are directly interchangeable, in particular, the feathering spindles (Belt CP spindles come in a discounted pack of four), and the washout (which is particularly weak on the King). There are reports that the E-flite Blade 400 feathering spindles also fit (edit to confirm).

The stock Esky gyros will not initialize unless the rudder trim is moved to the center.

Unless using a heading hold mode gyro, the tail will tend to swing when the collective is moved, due to changes in the torque reaction and no revolution mixing.
