AC3.3 TriCopter Improvements, need Input and Testers!

As part of my work to fix the RC Map problem for AC3.3, it makes sense to fix the Tricopter tail servo problems at the same time.  The timing on this work is really tight as we're down to the wire to…Continue

CBC Documentary: The Age of the Drone

On February 19th at 9PM, the Canadian Broadcast Corporation will air a new documentary on drones, following up the one they did last year called Remote Controlled War.  Last year's was more focused on the military aspects, this new one is more commercial/recreational.

I'm not sure what the availability will be for those outside Canada.  Hopefully our…

Iris/Pixhawk Cold Weather Testing

Posted on February 18, 2015 at 5:00pm 27 Comments

Last weekend I drove up north a bit for some real cold weather testing of my Iris+ equiped with Pixhawk.  I had to get up early in the morning to catch -30C temperatures which is about as cold as I'm interested in testing.  At -30C, my gloved fingers froze after a few minutes.  Not quite frostbite, but deep into pain territory.

Spurred…

Dear Mr. Lefebvre,

I saw some videos from your heli in Loiter Mode and thought wow this heli is standing rigid in the air.

I'm using a TREX 700E and want to fly this heli with apm 2.5 version 2.91 autonomously.

Currently I want to adjust the PID parameter. The stabilize and the Altitude Hold Mode is working perfect, but I have some problems with the Loiter values.

So would it be possible to send me your PID values of the loiter mode? I think they have to be very similar.

Thanks.

Nice Greets from Austria

Hi Mr. Lefebvre, 

Thanks for getting back to me.  Do you have any suggestions in terms of renting or hiring aerial videography crews or drones?  

All the Best, 
Jon

Hi Rob,

Interested in making a Tandem out of 2x 800 sized helicopter. Just interested to discuss your thoughts.

Hi Rob, I saw your DroneCon talk on youtube (which was great, thanks!), and it looks like you got cut off towards the end there. By any chance is the full slide deck available somewhere? Or was there much more left? Thanks!

Hi Rob, i know you had a lot to do with AC yaw control, could you confirm if motor values are used in the formula for the yaw servo control? In other words if running a motor in a wrong direction would affect the yaw control. If so is this something that appeared in the code since 3.1.3 or was it there before? Thank you!
