Helicopter Vibration Levels

I just wanted to make a post to specifically address the issue of vibrations on helicopters, as I am seeing quite a few logs which exhibit excessive vibrations. This not only affects Loiter, but can…Continue

Warning about Helicopter Power Supply!

I've posted about this before, but I feel I must reinforce this:You MUST use a completely independent power supply for your APM or Pixhawk than you use for the Servos.  DO NOT use one BEC to supply…Continue

Who wants to alpha test Flybarred Acro code?

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

Well, the moment we have all been waiting for in Canada is finally here.  Transport Canada has published the new UAV regulations.  It is important to understand that these regulations effectively come in 2 parts.  Basically, you have one set of regulations for UAV's less than 25kg and for simple…See More

Now we're cooking with gas!

I have just completed a project to build a helicopter with a gasoline engine, controlled by Arducopter (of course!)  This helicopter serves as a test bed for future gas heli development work for a client of mine.  The goal was to prove out that it could be…

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

Posted on February 3, 2014 at 1:10pm 335 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…

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!
