"I'm not sure why that would be.  You'll have to direct that question to one of the QGroundControl developers like James."

"I've been trying to build QGC with mavlink v0.9 on Linux (Fedora Core 16) and I have had nothing but problems.  It seems that the v0.9 branches of QGC and Mavlink are not actually using the same versions of the header files. Has anyone had…"

"the mission planner is mavlink 1.0 ready (compile time option), but will be a switch to 1.0 when needed. I dont support both because there are structs that have been modified between the 2, also the wp packet structure and a few other things has…"

"What are the plans with the mission planner? Will it support both, or switching entirely?  I will likely match the path taken with the mission planner with copter-gcs. Thanks, Bart."

All,Which version of MAVLink does Arducopter v2.5.3 use?  I want to used it with the latest version of QGroundControl, but the latest version of QGroundControl used MAVLink v1.0 and I can't seem to get QGroundControl to connect to my APM with the new v2.5.3 release.  Can anyone advise as to which version of MAVLink Arducopter v2.5.3 uses and how to connect to it with QGroundControl?See More

"David, have you successfully been able to get a GPS lock? I was able to get a lock outside, but it took a long time before it happened.  After the first lock all subsequent locks were relatively quick."

"All RC transmitters are different. Some go one way, some the other. Just reverse your rudder (yaw) channel on the transmitter side. "

"No, I haven't been able to get a GPS lock yet. I'm gonna take it outside this week to see if that cures the proven. I think it should though. I still haven't figured out why my controls are reversed or how to get them back to normal."

"Are you getting a GPS lock after you arm it? I am having a similar problem, no GPS lock."

Donald R. Poole, Jr. replied to Donald R. Poole, Jr.'s discussion Ardupilot Mega IMU Shield/Oilpan Rev-H Gyro Calibration
"Well, it looks like I solved my problem.  For some reason I have to arm the copter with no-throttle and full-left yaw.  And disarming is no-throttle and full-right yaw.  Why would my controls be reversed?"

Hello Fellow DIY'ers,I have recently bought a ready-to-fly w/ basic electronics Arducopter 3DR Quad for Udrones and am having trouble arming my quad.  I read the wiki for the arducoptor and the autopilot mega to gain an understanding of both.  But, when I power up the copter the A & C LEDs (Gyro Calibration and GPS Lock) keep flashing in the alternation manner and never go solid.  I even took the copter outside to try and allow it to get a GPS lock, but it still failed to obtain a lock and…See More
