Missing parts
Bought this to use with Mould King QJ loco. Joystick controls work fine but the joystick extensions shown in the picture for the controller were not included. Also note that the buttons on the top of the controller are purely cosmetic and non-functional. The motor rotation for each of the 4 channels can be changed using the small switches on the controller. Cable and battery perfect. No instructions provided but all fairly obvious. To connect the controller to the battery, press the on/off button on the battery and switch the controller on. They should connect instantly. The controller and battery can be charged using a USB charger (not supplied) and the USB cable provided. I have found from past experience that these batteries/receivers can easily be damaged by over-charging. Mould King recommend a charger having a power output of no more than 1 amp. Once charged, the charger should be disconnected. It is also important not to overload or short out the battery outputs. Would have scored 5 stars had missing parts and instructions been provided.
