"I agree Chuck, and this is why I am glad commercial platforms are priced much higher than amateur systems.  You either have a lot of time or a lot of money (or both!) in a system, which hopefully keeps the inhibitions high.  Makes me think…"

"I had the external compass installed 180º wrong. So it was doing the same as your copter. I just put it right and now it works great! "

""... Fly with a network printer and let the printed sheets with data drop overboard? (sorry couldn't resist...) " that was good ... The answer is simpler, I already have to Radio modems able to cover up to 20 miles, having…"

"Hi, Well if you can get that to do SPI command and serial data, that would be the easiest. Then you need to write some extra code to set up your connection in SPI (remember to add a mutex, there is one in the libraries) and just connect its serial…"

"Thanks for your answer, so I need to get back to arduino programming to make this work :(  but how about the hardware connection ! any idea ? if I realy need all those connections:…"

"Hi, All you have to do is basically to locate, in GCS_MAVLink.cpp: void comm_send_buffer(mavlink_channel_t chan, const uint8_t *buf, uint8_t len) { switch(chan) { case MAVLINK_COMM_0: mavlink_comm_0_port->write(buf, len); break; case…"

"Hi Cody O, I'm building a similar project like yours, and I would like to ask you for your expertish on that matter. Did you manage to connect ardupilot to an ethernet device? Did you try this one https://www.sparkfun.com/products/9473 or…"

"OK, Tried the something similar yesterday. Not an expected outcome. The unit was decending  at its last  (second last) waypoint as expected (land command on 5th wpt) after 4 waypoints and auto take off. Pressed restart mission about 10…"

"The battery was not changed, it was fresh before the first/successful flight (takeoff, go to 25 meters, hit 3 quick waypoints all within a few 100' of each other then land) which was less than 2 minutes long (normal flight times for my setup…"

"Hmm, nasty. Feel for you. Was a new battery put in, that is the unit rebooted? Maybe a re write of the flight plan on the mission planner might reset the plan? Or maybe trying the " Restart Mission" action button? I could be wrong but…"

"Hmmm...I had a very similar thing happen today.  I performed a flawless autonomous flight and after landing and waiting for a few minutes tried the exact same flight.  The copter took off and headed at top speed in almost the exact…"

"Hi CodyO, Does the light blue track on the mission planner stay stable around the copter on the ground before launch? I find that the Media Tech GPS is slow and not as good as the UBlox Lea6 version. It can show the gps tracking around my general…"

"Sorry about the bad flight! Grab something like this http://hobbyking.com/hobbyking/store/__14521__Hobby_King_Discovery_Buzzer_.html and hook it to an unused channel if possible. Great for locating tree-dwelling copters."

"There are a few apps that dump all of the phone's sensor data.  AndroSensor and Z-Device Test are two that I like.  GPS Essentials and GPS Status are pretty useful also."

"Thats interesting, What did you use to scan the area with on your cell phone? Thanks"

"It's the Turnigy HAL.  There is also a hexacopter version.  The dome is quite large and provides excellent protection to all the guts (see video!)"
