"do not use internal and external compass at the same time!!"
"thanx Clive"
Can any body help me to solve an issue...wheather APM2.8.1 firmware uses haversine formula or equirectangular approximation in case of waypoint distance calculation in navigation??In the distance calculation function belowfloat get_distance(const…

"if your connectors are ok then just replace the cable by simply detaching them from cable... it is quite simple to detach the cable from those SMD connectors by using only a small pin . after detaching just uncouple the leads from cables by using…"
"either u can manually repair it or try to search in ebay"
"u can do calibration inside but to test feature related to GPS u need to place the quad outside...."
"from APM mission planner teminal tab u can check the sensors by typing simple commands.....connect and type help u can see several options... to stabilize the quad first try position hold because it is a semi autonomus mode... u can control the…"
"okk best of luck....., while enabling pre arm chk make sure all of your sensors are working and calibrated properly.... otherwise apm will oppose the copter to arm"
"yes make pre arm check disabled or skip GPS"
"you must wait for some time to lock gps... if GPS is locked u can see blue light of APM become solid..."
