After IMRC released their drawings for the larger flight controller bays to accommodate a Pixhawk flight controller the next question was on how to get the flight data read out from the integrated OSD due to the lack of the compatible Naza GPS unit. Pending the availability of a converter or the APM copter feature to output NMEA streams on one of the telemetry ports, I opted to install a small secondary GPS unit. This thing is a suitable mount and case for the Hobbyking Micro U-blox Neo-6M GPS unit (e.g. part of this set: http://www.hobbyking.com/hobbyking/store/__74654__Micro_HKPilot_Mega_Master_Set_With_OSD_GPS_Telemetry_Radio_PDB_BEC_Power_Sensor_433Mhz_APM_.html) Case, print with 20% infill and the mast with 100% infill. Use CA to glue together. Center mast can be shortened if required.
