No actual RC out on channel 7/8 unless safety switch pressed even though it's shown to change.

Started Feb 21, 2016 0 Replies

Hi folks,I've just noticed that the logs / tuning graph shows RC 6/7/8 having output even though there is no actual output. Once I press the safety switch then the outputs really do spring to life.I…Continue

Crash - why did it flip?

Started May 20, 2015 0 Replies

Hi folks,I had a quad Pixhawk, 3.2, which has had two "wobbles" in the air. Both occasions it looked like one motor shut down. On both occasions it turned back on and had enough height to recover…Continue

"I cannot see what the CPU is. If it really is then is it not like buying a 486? I just found out all my pixhawks are essentially bricks soon. If this is APM then why would you?"

Hi folks,I've just noticed that the logs / tuning graph shows RC 6/7/8 having output even though there is no actual output. Once I press the safety switch then the outputs really do spring to life.I have channel 6/7/8/9 set to rcPassThru (1) and watch the values in the graph shows the outputs correspond to the inputs however there is no actual output (I put a small servo on as a tester).Once the safety switch is pressed then the servo springs to live and does what it's told.I don't think this…See More

FLIR Tau2 640 + GoPro and 3D printed case

Posted on March 5, 2015 at 4:00pm 17 Comments

I've been doing a bunch of filming with my Tau2 (more to come on that) and recently I have needed to film with both the Tau2 and a GoPro with the aim of blending the video.

3DR battery tray and camera mount.

Posted on February 12, 2012 at 3:30pm 1 Comment

Not being overly chuffed with the battery mount on the 3DR and wanting somewhere to mount a camera, I decided to make another layer to the quad. A third plate below the quad seemed idea.

The normal plates have a series of 3 holes in the middle of each edge which seemed a perfect option to mount stuff. I…
