SweepWings Flinch with Pixhawk 2 Cube and PX4 VTOL TiltWing/Tailsitter

- I want to document the process of building a TiltWing/Tailsitter with the SweepWings Flinch, Pixhawk 2 Cube, and PX4 VTOL firmware. Not sure how this will turn out but I'm excited about the prospect of flying a tiltwing. Once I get this build dialed in I will share the 3D printed motor mounts. Please stay tuned as I will be uploading more videos of my progress. #pixhawk #vtol #sweepings #flinch #px4 #uav
Cool! Can't wait for the results. Good to see someone doing something different.
Thanks Ken. Me too. Hopefully I can get in the air soon.
Thanks so much Dennis. Looks like I'm going to scrap my Tricopter/Wing VTOL config and go with this design.
A very interesting project, thanks for the sharing and curious to see the continuation. The vertical plans and the landind gear should help to balance the CG.
I hope you're right. The CG is actually pretty decent right now after getting a bunch of the electronics installed. Will share more soon. Thank you.
Hi Dennis, you got more videos of this project? I have a question if I may, I'm building a mini talon with pixhawk 2.1 cube, my question is :- if the battery is connected and plane is armed, if you put it in RTL mode should the motor start? I'm talking about
If the plane is still on the ground just bench testing. Or the plane needs to be a certain altitude or distance from where it's got 3d fix before RTL kicks in? Many thanks. This is my second question, my first question was about 5 years ago I can't even remember what the question was !! 😁 so much goes on in this hobby. So much changes so quick lol thanks again
Can you share the params for this build? My Tailsitter doesn't seems to behave as expected after following the official documentation.
Thank you for sharing this project, it helps very much that you can't imagine. My only concern is, what if we try to set the flying wing up with just a single rotor and two servos? Will it still hover in vertical position with the help of large control surfaces?
Not with a pusher propeller, but a tracker propeller of course
Please do more pixhawk 2 videos. im still flying on an apm 2.6 in a skyhunter San Antonio Tx.
curious to see if the px2.1 is worth the upgrade.
You got it. I still love my APM boards. They are always up to the task. Thanks for following along.
Hi Dennis, I really like the direction you are heading in, I was wondering if you had the Intel Edison board in the pixhawk 2 or is it flying solo?
Thanks Randy. I'm still experimenting with this and right now I'm only using Pixhawk with no Edison board.
Hi Dennis, Congratulations on the Tailsitter project.
Friend I am setting up a similar version and I am in doubt about Q_FRAME_TYPE, which use X or H. Which one did you use and what is the rotation of the motors for CW and CCW. Would you help me?
I'm fairly certain that Q_FRAME_TYPE does not apply to tailsitters. Check this thread for the necessary parameters: discuss.ardupilot.org/t/dual-motor-tailsitters/15302/2 There is a lot of discussion in there but I would recommend bookmarking it and coming back from time to time. That's what I do to stay up to date.
I found the PX4 firmware difficult to work with. The documentation was too sparse, and the developers at the the time (mid 2016) weren't responding on the PX4 forums. Ardupilot have been making steady progress with this style of configuration, and there's active thread on their forums that may help you out: discuss.ardupilot.org/t/dual-motor-tailsitters/15302
The PX4 is a lot more than difficult to work with, it's impossible to ever get one working! I tried for 3 years to get a PX4 to work installing hundreds of updated versions of the firmware with bug fixes that came out almost every day and finally gave up after it wore out just from handling it so much!
Thanks Guy. I didn't realize Ardupilot was that far along. I've used it for a Tiltrotor (Firefly 6) but wasn't aware of Tailsitter support. It's definitely my preference so I'll start there. Appreciate the heads up.
Ardupilot FTW

Howdy Dennis, any chance you can upload the stl files for those motor brackets, please plus cake? Matt
Matt, are you going to modify them because they are designed specifically for this wing and Lumenier motors? When I get this fully functional I'm going to work on designing a few variations. Let me know what you're thinking.
Howdy Dennis, I've got a collection of wings here that I could use to put twin motors on. I know they won't be perfect, however if they're opposites, if rammed, sorry "gently placed" onto the wing in the same place on both sides, they should skew evenly. Well thats my logic anyway. As for the motor mount being for the Lumenier motors, if they're not standard mountings (16x19), enabling a standard X mount to be fitted would be best as that would cover all the 20' sized motors. Matt
Matt, these are the motors I'm using:

I'm not at my computer so don't have exact dimensions atm. But here are the files so maybe you can look:

Flinch right motor mount:

I'm going to work on improving this design next week. I need to add more distance between the prop and wing by lengthening the mount. Right now the props are too close (< 5mm) from hitting the wing.
Thanks for the feedback.
I can predict how it will turn out, if you are using a worthless Pixhawk with it's crappy firmware it won't ever work at all!
What makes you say that? I've done lots of builds with Pixhawk over the years and never had any major issues. Community has been very responsive in times that I did struggle. The code is open source so feel free to contribute and make it better.
steve c this will work Dennis is not one of the stupid people that can't comprehend. Are you saying you are.
The PX4 might work if there is an F3 hiding inside it! LOL
Steve you obviously no nothing about pixhawk other than comments online from people like you
Can't wait to see the flight trials Denis. So far the successful hovers I have seen are on wings with huge aileron surfaces so it will be interesting to see how a regular wing responds.
