I'm trying to find a way to do a controlled slow, smooth yaw (though if it can't be smooth, I can live with it) while in auto mode hovering at a waypoint. I've tried using "wait for heading" (mav_cmd_condition_yaw) but nothing seems to happen. Am I m

Read more…Hi. After weeks of fighting this I'm getting pretty close to giving up on ever getting Er9x firmware installed on my 9x transmitter, using a SmartieParts SP Basic programmer board.
The 9x is new and of recent vintage with the programming pads in the r

"The FAA responded that it would have the Chief Counsel’s Office again review my request. It seems the third time was a charm and I got an answer that may not make many hobbyists very happy. F

Oh goodie. The FAA has announced its ultra-rushed plan for a drone registry -- they desperately wanted to get this on the books before Christmas. It's worse than even the most vocal critics had anticipated:
Read more…I'm unclear on how sonar and LIDAR are used for reference altitude readings as opposed to barometer-based altitude readings. I assume that sonar or LIDAR (when available) are used for altitude references below a certain altitude as determined from th

PLEASE NOTE THE FOLLOWING! (As the saying goes, not th

I have a new pair of model 1 915mhz radios -- I haven't worked with these before. The ground side plugged into USB fine, green light flashes once a
