ardupilot/ArduCopter/GCS_Mavlink.cpp
Andrew Tridgell 7efca1881c Copter: fixed a problem with initial parameter fetch 
if the GCS connects before the motors have been allocated then it will
get an incorrect parameter count from the MAVLink param protocol. We
need to prevent the PARAM_REQUEST_LIST message from being replied to
until motors are allocated which is done as part of init_ardupilot
