I was wondering if someone would look at my Autotune log file and be able to tell if the Roll and Pitch PID’s are reasonable. They seem too high from what I’ve seen, and I’m a little afraid to fly with them. I’ve recently re-built this with stronger frame due to vibration problems. Vibrations are now low and no clippings.
I don’t think you can add any weight. In fact It’s probably under powered/over weight now. Perhaps you should consider 12S with 14-15" props.
Regarding the tune, post a log of another flight, not an Autotune log. Do some hovering and then some pitch and roll as aggressive as you feel comfortable with.
I’ll fly again when I get some good weather and upload the log. I’m just not sure what PID’s to use. It will fly with the default’s, but flies a little sloppy. I can reduce the weight a little by rebuilding the landing gear, and maybe cut holes in the body if necessary. Also I have some 20 inch props that will fit this frame I think will help the throttle hover value.
Using eCalc I should be ok, if I’m entering the right values. There is room for improvement with weight and prop size though.
