I've put together a new scratch build and was running Autotune on it yesterday. Had Autotune OFF at the time. Quad started slowly rotating about the vertical axis while flying. Did a rough, (but not too rough) landing, pulled all motors and re-secure
Recently I've come across the suggestion that when you are using the Pixhawk power module, you should snip the (+) wire (middle one) that connects the ESC to the Pixhawk unless you are using a Zener diode in the line to prevent over-voltage. I've got
I'm having a problem with a Pixhawk that came with a 3DR DIY 4X kit. APM Planner is reporting "Bad Compass Health". The compass is an external uBlox GPS combo that came with the kit.
Hey all- I've got Pixhawk set so that when my battery falls below 25%, the aircraft automatically descends and lands. However, when this happens above 20 feet, the aircraft develops vortex ring instability, which is followed shortly thereafter by a c
I've just finished independently autotuning pitch and roll for my little quadcopter (Emax 2204-2300, 6030, 310mm, 702g) however, the quadcopter is unstable using these values while in Autotune mode for yaw. The P for roll is 10.18, and the P for pitc
I've got a Turnigy 9X (TGY9x) transmitter that I have been using for basic control for about 6 months. I am still using a stock ROM in the transmitter. I would like to add multiple Flight Mode switching ability. This would ideally take advantage of t
Most quadcopters have motors where the propeller is situated on top and the motors pull air down and through. I am interested in building a quadcopter with the motors above the propellers. Is this simply a matter of building a frame with appropriate
Is there a best way, (secret way?) to remove the switch, buzzer and other plugs from their sockets in a Pixhawk? Pulling on the skinny little wires seems like a bad idea. I've tried leveraging a knife blade beneath the plug and then twisting...this w
I've got a genuine Pixhawk that I bought from 3DR that I am trying to get configured properly. I am running Mission Planner 1.3.36 and have run through the basic configuration process (compass, level, radio, ESCs), but after this when I put the prope
