"Yep, I remember and like the 1/2 pool noodle crash plate on the bottom. I have a section of ABS septic line under both ends of my fuselage that I reshaped with a heat gun as landing gear. Springy and unbreakable. Thanks for the response."
"Hey, great to hear from you! You are precisely correct w/regards to getting the compass away from electronics/metal to reduce interference. Murray, what are you flying now? I've got a couple of variants of your design on my drawing board now. I'm…"
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…
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…
"Ooooh, nice! Thanks for sharing this. I'm impressed w/the code as well as the Big X platform. It is a nice big technical drone like I wish we'd see more of in the market. Best regards and happy holidays to you and your team!"
"I did just that. Didn't work after installed in the 3DR X4. So then, I swapped in the GPS/compass from the bird that I'd robbed the second Pixhawk from, and you guessed it, everything worked fine. The kicker is that when removing the suspect…"
"I've got two GPS/compass setups. Same errors with both. If there is a wiring problem it's gotta be inside the Pixhawk unit. Chad Frazer said:
I had a similar problem, turned out to be a crossed wire going from the gps/mag unit to the pixhawk. Do…"
"Thanks for responding Martin. "Yes" to both questions: arrow is facing forwards, and light does flash blue. Both of the external compasses report "bad health" when plugged into this Pixhawk. I'm starting to think that this Pixhawk has a factory…"
"Okay, with 12c and GPS unplugged I can do a compass calibration. With just the GPS plugged in (and 12c cal unplugged) I can arm and spin the motors. However- I am not getting a GPS signal. I've tried this with my two uBlox units outside with an…"
