"I had this same error repeatedly. Compass variances, failure to calibrate compass, etc. I finally figured out that the problem was that my external compass with GPS was too close to my camera gimbal (mounted on the top side of drone). I relocated…"
"Wow, you are lucky the copter survived that flight and landed so well. My failures usually end up with the camera embedded in the mud and pieces scattered everywhere.
I am not an expert log analyzer, but the log clearly shows errors in GPS,…"
Pixhawk is a robust autopilot for a fixed wing aircraft by itself when loaded with Pixhawk or PX4 software. Do you mean that you are to use the Pixhawk in an aircraft design or perhaps modify the software for the Pixhawk (which is open…"
"I would think the transmission lines will interfere with the compass due to their magnetic field. If this happens, you may want to find out how to disable the compass."
"I made a test rig out of an old piece of plywood and some nylon rope. Works like a charm when you want to test something without killing it. See this youtube video.
I have a Quanum Q-2D brushless gimbal on a quad with Pixhawk controller. This is the first time I have used a gimbal. I was unable to make the Pixhawk to Gimbal connection work using the Aux outputs of the Pixhawk connected to the pitch and roll…
"You need some kind of shock/vibration absorbing mount plus an assembly with a tripod screw to hold the camera. You could get a vibration mount from hobbyking or ebay. Add a tripod mount from ebay. Aseemble and adapt to your quadcopter frame and…"
"I had a similar problem and never really solved it and gave up on Pixhawk and went back to APM controllers. I had a quad working perfectly with pixhawk. Then I think I upgraded to a new software load and could not get motors to spin or calibrate…"
"One thing to try is connecting up the battery/BEC so the APM is not relying on USB power. Other possibilities are the USB cable (try another cable) and the USB connector on the APM, which is often not properly soldered when it was built (try slight…"
"Chris is right, you should disarm before turning off the transmitter and you should set the RC Failsafe function and test it with the props off. Modern RC transmitters do not use much battery power so there is not much advantage in turning them off…"
I have both the DX4e and DX6i transmitters and both function well. But I am not sure if either has better performance in terms of range, susceptibility to interference, accuracy of the controls, etc.? Does anyone know if there is a true performance…
