Who wants to alpha test Flybarred Acro code?

Started this discussion. Last reply by Jim Johnston 8 hours ago. 32 Replies

I am attempting to fix the flybar acro code, wanted to get it out with the upcoming 3.1.3 release, but I'm in a bit of a pickle.  It compiles in Arduino, but won't compile in Make for PX4.  I assume…Continue

Helicopter Presents Attractive Alternative to Multi-rotors and Fixed-wing UAVs

Posted on February 3, 2014 at 1:10pm 305 Comments

I've been working on a new helicopter platform the last few months. Based on an MSH Protos heli which I chose because it's an extremely light weight platform, weighing in at only ~1200g without battery. It has a full belt drive which I much…

Merry Christmas and a Happy New ACRO!

Posted on December 24, 2013 at 7:01pm 16 Comments

3.1 was released just in time for the holidays, but I felt the new Acro Mode we have developed has not been adequately demonstrated.  So I shot this video to show that Arducopter now has a competent Acro mode to go along with all the other functions.  This is kind of a big deal to me, as I am interested in learning acrobatic flying, but I really appreciate having…

Group Attempts Prison Contraband Deliver with Hexacopter

Posted on November 27, 2013 at 4:15am 7 Comments

I think this is actually the second attempt at this.  Wasn't there one last year?  Good to see that they actually caught the people involved and arrested them.  Hopefully it won't result in a knee-jerk reaction, but I doubt it.  The article is horribly written, but at least they didn't call it a "drone".…

Extreme Arducoptering

Posted on November 3, 2013 at 6:30am 6 Comments

 

On Friday we experienced very high winds, 60-90km/h, or Beaufort 7-8, this caused damage in the area, actually knocking over some trees, etc.  I decided to go out and test the wind performance of my F450 quadcopter, see if it's even possible to fly a quad in such conditions, and test the inertial Loiter performance.

 

Overall, it went fairly well.  Flight…

Robert thanks for your input the 1/8 aluminum on  on the fuselage will be a milled out channel running  half way down the side of the plane    to attach the wing the horizontal stabilizer and the vertical fin to a Exoskeleton about 1 1/2 pounds the rest of the plane is foam and fiber glass there was no distortion welding we had it clamped down  pretty good Thanks again Carl

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
