Some how I missed this thread until today. Congrats on a successful build and working out the tail issues. I was kind of surprised to not see Litterbug in here anywhere as he is our resident tri copter mad scientist. He uses Dronin on his quads and does a lot of the testing for the devs. they seem to have matered a lot of the typical issues on quads.
Might be worthy to look into for a future build or when the time comes to update this once clean flight goes by the way side all together as planned.
Thank you for the compliment And tip! David (RCExplorer) himself said Triflight might be a good firmware to run on this tricopter, but I'll have a look at Dronin as well..
Thanks again!
