Design and build of a coaxial drone

Congratulations @jasclarke308 on making this fly!
Could you post a log from this flight?
I assume you created a new frame type to support this; could you post a link to your fork of ArduPilot?

I’m sure you will need to add some support (or redesign) to use an FDM printer:

I have the cheap Creality 3D printer but so far never failed to print parts at least the complexity I put it through…

Should be ok?

Hi Guys,

got the Link to that Thread from iSkyMaster, thanks for that.

I’m working on a similar build, bot with a single rotor. So far I cannot select Singlecopter as Frame. Please find the detailed description of my issue here: Singlecopter Frame

Do you guys know how to solve my issue?

Thanks and congrats to your successfull project jasclarke 308!

Thanks Mark, I’m quite new to github but have created a branch here: https://github.com/jasclarke308/ardupilot/tree/Coax_Thrust_Vectoring. It’s still based on the Coax Copter code with an additional parameter.

I wiped the logs from that flight but will try to fly more this coming weekend. I expect them to look quite bad though; it’s definitely not flying anywhere as well as I’d like. It was however quite fun to test my test piloting skills.

Greetings @jasclarke308. I was wandering if you can explain how you designed the thrust allocation matrix for this vehicle.

Can you share your parameter files for setup! I am going to start printing one this week!!

can it work with apm 2.8 controller

@Asty_Official No, APM 2.8 is no longer supported by ardupilot. You could load older version of the code but they did not have this functionality when the APM 2.8 was supported. I believe the last version that was supported was ArduCopter 3.6.9, but I am not sure of that.

Im saying that can i make coaxial drone with apm 2.8

A coaxial helicopter or coaxial copter? For a coaxial helicopter, you would not be able to do it because the firmware would not have the updated motors library that supports independent swashplates for a coaxial helicopter. However You could do it if you used a ganged swashplate that uses mechanical mixing.

I don’t know anything about coaxial copters.

This model is in the code of that folder

Hey Jason,

Seems the file links have expired :frowning: Wondering if you could reupload them. Thanks!
