The manual does provide information - but not pictures - on the servo plug positions.

If the controls still do not respond properly after ensuring the servo reversing switch positions are correct, you may also check the servo connections to the receiver of the 4-in-1 unit. These should be positioned as follows (when viewing the helicopter from behind):
Channel 1 – Right-hand rear “aileron” servo
Channel 2 – Forward “elevator” servo
Channel 6 – Left-hand rear “pitch” servo
