The HoneyBee CP2 is a nice little helicopter, but mine wasn't really set up correctly out of the box, so here's the sum total of my knowledge having got it into a flying state

For most of this setup, you want the controls in a neutral state. Unplug both motor connections on the 4-in-1 (on the side where the battery plugs into). This is to stop it spinning up and hitting you in the head/hands/arms etc.

Switch on the transmitter, and plug in the helicopter battery. If you move the right stick around, the servos should move.

Controls
Check the controls work as they should. Right stick forward should tilt the swashplate towards the front of the heli. Back should tilt it back. Left and right should produce corresponding tilts on the swashplate to the left and right.

Moving the left stick up should see the whole swashplate move downwards, and you should be able to see the main blades angle upwards a little bit. It's quite a small movement, so don't worry if it doesn't move much, just make sure it moves.

Left stick left and right won't do anything at the moment because you've unplugged the tail motor, worry about this later on.

If any of these controls are wrong, you'll need to alter the switches on the front of the transmitter. Mine are, from left to right: Down, Up, Down, Up.

Neutral Control State
For all this setup, you want the controls in the following state. Both sticks centred, and all the trims centred as well. Flick the idle up switch towards you. Make sure the motors are unplugged first though

Servo Arms
When I got my heli, the servo arms weren't straight. With the controls in their neutral state, all the servo arms should be horizontal. If any of them aren't horizontal, unscrew the small screw that holds the arm in, and pop the arm off. Put it back on as close to horizontal as possible (you won't get it exactly right due to the little splines on the servo output shaft). Now use the transmitter trims to get the servo arms level.

Swashplate
The swashplate needs to be level with the controls in a neutral position. Adjust the 3 links from the servo arms to the swashplate until the swashplate is nice and horizontal. (They adjust by screwing in and out on the metal rods). Now waggle the controls around a bit, and check that the servos are still free over the whole control range.

Pitch links
Now you need to set the pitch of the main blades. Look end on at each blade. With the controls at neutral, the blade should have zero pitch - i.e. it should be perfectly in line with the flybar (the rod with the paddles on each end).

If the blade is angled, unclip the link that goes down to the swashplate. Unscrewing this will increase the pitch on that blade, and screwing it in will reduce the pitch. Adjust these links until both blades are horizontal.
