Hi,

I recently discovered a post on RCG here back in May 2015 from a new member about using a single Pixhawk for VTOL control on the BirdsEyeView FireFLY6. It lead to the PX4 page below describing some development firmware for the Pixhawk. Does anyone know if there have been updates to this development or how to obtain the firmware for testing?

VTOL Firmware for Pixhawk

PX4 Page to BirdsEyeView FireFly

Thanks.

Hi Greg

Happy New Year. Please, can you find the attached image for my drone. I want to start with hexacopter mode and do the transition to fixed wing mode. I will use PX4 and qgroundcontrol. Please , can you help me in this.

Hi Greg

Thank you for your reply. I will let you know what will happen to me. Thanks again

Hi Nada,

If you use the APM stack with APM: Plane v3.6.0 release firmware then you can utilize the QuadPlane features that you desire. Here are a few links to get you started. You will see my QuadPlane projects for Bix3 and Ranger EX in the forum link below. At this time, folks are having QuadPlane difficulties using APM Plane v3.7.0 so please start with v3.6.0.

Nada,

After looking at your image, I would choose to treat the frame as either a quad or a tri, not a hexacopter. If using a quadcopter or tricopter setup, the front left two motors are treated as one in parallel as are the front right two motors. The rear motors would be left and right for a quad or treated as two in parallel for a tri.

Break the problem into basic steps as follows:

  1. Vertical Takeoff and hover - Test vertical lift to verify thrust/weight level (correct motor/prop choice)
  2. Normal flight with normal gear or belly landing (fly it like a normal plane)
  3. Transition from take-off to flight
  4. Transition from flight to landing

Thank you Greg for your help.

Hey guys

I accidentally stepped over this discussion and just wanted to let you know that we've added a new tiltrotor configuration to PX4 a few days ago (for the E-flite Convergence):

http://diydrones.com/profiles/blogs/e-flite-convergence-with-px4

This update also improved the Firefly6 handling and is now available in the developer build (this is bleeding edge code so be ready for anything ;)).

Have fun!

Hallo Andreas, thanks a lot for your efforts and for sharing. Just a question, as any of you devs actually flown this new firmware on a firefly6 ?

Of course we have! Just yesterday :)

thanks Andreas

Hi Andreas,

Thanks for the information. I have also found a video on YouTube below. I think it is you but I could be wrong.

E-flite Convergence Autonomous Mission Flight

@Paul btw, I think it's a fair question and I understand very well why you would ask ;)

@Greg yes that's us (UAVenture). The updates to PX4 came from the work we did there.

After looking through the posts here I gave the build page for the Firefly on PX4 an update as well: http://px4.io/portfolio/firefly-y6/ . All that is really needed to get PX4 going on the Firefly (or the Convergence) is selecting the airframe in QGroundControl.

The more technically interested will find this commit informative: https://github.com/PX4/Firmware/pull/6245/commits/364a57016fe88abbd... . It shows the basics that were necessary to get the Convergence going (startup configuration and mixer).

I just acquired the FireFLY6 and am puzzled how to bypass the AVA key. $499 for mapping and camera control? Can I start with the provided (birdseye) firmware and modify it in Mission Planner? Is there now support for Tiltrotor?

Hi Paolo and babak,

When you say, "I downloaded the Y6 tiltrotor BirdsEyeView configuration", I am not certain what this means.

If you meant that you downloaded a Pixhawk configuration file then you do not have the required custom FireFLY6 firmware for the Pixhawk.

If you meant that you downloaded the custom FireFLY6 Pixhawk firmware, then you still need the AvA key to activate it.

Lastly, if you are using the older "Classic FireFLY6" firmware, then you need the Transition Bridge module and a second flight controller; one for hover mode and one for forward flight mode.

I hope this helped...

Is there Mission Planner .px4 file for this? Will Mission Planner work after loading with QGC?
