Hello everyone, I feel the time has come to make an announcement, which I've been avoiding for a few weeks now, but which I can't put off anymore.

As some people are aware (and some maybe not) for a little over a year I have been doing development work and community support as a full time job, with the generous support of 3DRobotics.  This represented a major shift in the direction of my career from industrial mechanical engineering, to this burgeoning field of aerial robotics.  However, 3DR has decided to discontinue that support.  As the project has grown in scope and complexity, the overhead time requirements just to stay on top of program development and developer group communications has grown with it.  Prior to the support provided by 3DR, I was moonlighting while maintaining a "day job" outside of the industry, but that ended up burning me out and I won't go back to that situation.

This has led to me scrambling to figure out what to do next in order to pay the bills, etc.  I actually saw the writing on the wall several months ago and began working in the direction to solidify my future in this industry, but the change happened a little before I was ready.

In any case, regretfully I must announce that my efforts to directly support the community, answering questions, analyzing logs and doing general improvements to the code will be ending.  I am committed to seeing AC3.3 finally go Stable for Tradhelis, and updating the Wiki to be up to date with this.  But beyond that, I'm not sure how much I'll be able to help out.

My hope is to produce revolutionary new turn-key UAV helicopter systems and use them for professional services, or 3rd party sales.  If I can make this transition, I will likely continue to do Alpha testing on new AC code and contribute new features.  I have almost completed design of an excellent new 700 helicopter design, and hoped to do a proper 500 size helicopter for mapping after that, but likely won't have the cash to bring these to market on my own at this point.  Unfortunately, due to timing, I may be entering into development contracts with other companies which will be a bit more "closed" in nature.

It is my hope that the community can get to the point where it is self-supporting.  We already have several members who are quite successful with helicopters, and are still coming around to help others, and that is encouraging.  Hopefully this can continue to grow.  I don't want to see Helicopter support in the code die.  Helicopter mechanics are largely a "solved problem", and this platform delivers superior combination of flight performance.  VTOL of a multirotor, range and speed similar to many of the foam airplanes used today, and absolutely unmatched stability and weather tolerance, while carrying payloads greater than any platform of similar size. And Ardupilot is the only full-featured autopilot system that will fly a UAV helicopter, unless you purchase military-grade autopilot systems. I feel, and I think the worldwide UAV community agrees, that Ardupilot is the most reliable, full-featured, high performance and cost effective autopilot system available.  The fact that it is truly open source, distributed under a GPLv3 license means that is flexible, extensible and capable of meeting the needs of all users, big and small, while reflecting a share-and-share-alike mindset.  And I don't need to tell you guys that Ardupilot is flexible and cost effective on the hardware side as well, capable of running on a wide variety of hardware systems from many companies offering differing capabilities to meet various user needs.  This could be anything from tinkerers and hobbyists, to small service companies, UAV builders, academics and research groups.  It's important that the project continues to keep UAV technology accessible to all, and not be locked down by big corporations or governments.

Best Regards,

Hey guys, thanks for all the well wishes.  Just to note though, that I'm not planning on disappearing anytime soon.  Just wanted to make sure people know what's happening and that I won't be available as much in the future.  Also, that the position of lead helicopter developer may be up for grabs if somebody is interested in taking it on. 

Hi Rob,

Many thanks for your support, you will be missed as one of the experts on this forum.

Good luck, and best whishes !


Thanks for everything Rob and while it's not the best news to hear that you're leaving, its exciting to hear about your own project(s)

As one doors closes, another opens.

Looking forward to reading and seeing your creations.

Really enjoying your acerbic observations on the Plexidrone Q/A thread over at RCG... thanks for all you have done for the community Rob, and if that work continues in the form of a new business enterprise then all the better.

Thank you for all the hard work and advancements made on the Heli program. I think any of us who have tried to use "Drones"for work and need something larger than a 800 size quad realize there is no better option than a Heli. We figured this out the hard way and now have completely abandoned quads all together for any real work. I hope this does not mean the end of development for the Heli project, but, I think it wont be. 

Keep in touch!


so sad to read that Robert. I just say thank you for the talks we started some years ago, and for the beatiful job you have done here. This a great loss. But It's totally understandable there are other priority needs. Maybe stop in Italy for a wee while when you'll be back from Australia ;-). 

Thanks Rob for so many years for the great efforts to develop traditional helicopter member pay and selfless dedication, so now AC3.3 FW has been perfected, these are for all to see. I also started from 3.2.1 FW, follow all the way Rob constantly updated firmware came to make my T-rex500 constantly reached new state. Get the news, really shocked, I could not believe this is true. But we bless Rob successful career, have the opportunity to come home and continue to develop the traditional helicopter firmware open source projects.
Good luck to you, our beloved Rob ......

Sad to see you go, Rob. I always thought you were a very balanced voice on these forums.

I know what you mean about the moonlighting thing, I'm going through the same now and it takes a heavy toll on life and family.


Thanks for all your help, best of luck to you and be safe.

Thanks for all the help you provided. Good luck!

Whoa, that was big news. Whatever it is you decide to do, very best of luck.

So sad. The whole 3DR thing is sad. Sorry that it has effected you. Best of luck.
