you mean that you can't get the MFC specific functions to work - eg. lights? Or with the sticks in neutral the trims don't move the servos at all? Try starting again with a calibration of the MFC as per the manual....

Also check that the 3-position switch on the MFC control unit, next to the on/off switch, is in the middle position. In 'position 1', the MFC is effectively de-activated and the truck behaves as if the MFC isn't installed. In 'position 3', the MFC ignores any RC input and only limited functions can be activated with the round push button switches - like a 'demo' mode for the lights etc. The switch needs to be in the middle position ('position 2') for the MFC to work fully with RC. It's easy for the switch to be moved when you turn the unit on/off....I've often done it....
