I finished my Tricopter LR build yesterday, after ordering the full package from David incl. emax 2207 1600kv, KakuteF4V2, etc. I really was planning to give dRonin a try (it was my first try) but after some hours I simply gave up and switched to Betaflight. The thing is, I am so comfortable with Betaflight and the available settings, I just wanted to get the thing in the air and maybe try again later.
To my surprise, after some PID tuning of the Yaw servo it is actually a very good flying Tricopter. It is by far not as solid on the tail as a racing quad with betaflight and all bells and whistles, but it is also by far the best Tricopter I have ever flown.
I setup the tail PIDs quick and dirty flying LOS in my garden with two 3s 4000mAh batteries, giving me plenty of juice to fly long and really feel the differences made. Now, I had to smile when I found this thread and especially Claude’s PIDs which are quite close to what I have found today with my TriLR.
But judging from your dump/diff, you are also not using the feedback from the servo, correct? Bugger, I really wanted to see how much this feedback changes on the flying characteristics of a Tri.
Maybe you have an idea what was the reason for my dRonin problems. The final nail in the coffin was the fact that the tail motor wasn’t running right when I armed the Tri. It was perfect when I tested it from the motor page, the idle speed was def. high enough, but as soon as the PIDs had their say, the motor sounded like one of the windings burned out and got really hot.
After switching to Betaflight the exact same motor/esc combo was perfectly fine and has been in the air without a problem for almost 2 hours. There was something not right in dRonin, but I followed David’s setup video to every single point (I had to without a clue about dRonin, as it was my first time).
When I could not find the mode “Tailtune” in my dRonin which David shows in the video, I gave up.
