Hello, im also having issues with drift, but only since installing dronin.
Im trying to get back into RC flight again so i decided to fire up one of the quads i built in 2016, it consists of:
naze32 rev6, et-160 frame, 1306 motors, 8A or 10A simonk escs, 4" 4045 dalprops, flysky 6ch rx, runcam sky+, generic 200mw vtx, some pdb. 3s 1000mah and 1300mah batteries. Cheapo beginner build basically.
I figured it would be a good idea to update to a more recent firmware so i initially tried to flash the latest cleanflight onto it, this made the FC unbootable and as i (a day of banging my head against a wall) later learned was because f1 support was dropped a while back.
After figuring that out i then installed the most recent version that did run, went out to fly and the quad flew like ass.
I figured they must have changed something about (the magic i dont understand of) the PIDs so plug the quad into my phone and loaded the default pids through ez groundstation, it flies better but still oscillates some.
At this point the quad still works in level mode with no issues, i walk back home after flying two or three batteries and decide to look up some other alternative to having to relearn the basics of tuning pids again because i hated that part the last time i did so.
Finding that dRonin has an autotune feature that is getting some praise and i check some videos of people flying with dRonin autotunes and it looks very good for the end user effort put into it.
I install the dRonin version that still supports f1 boards, (artifact?), follow guides to configure it and go out to do the autotune late at night.
Autotune does its wiggly bit, i then land, go back inside and apply the settings.
The next day i go out to try to fly my newly tuned quad, im a pretty novice flier so i usually take off and land in level mode so i take off and the quad starts pitching forward straight away, i pull back on the pitch but it keeps going until it crashes.
I try again, pitches forward again.
I try taking off and then quickly switching to whatever the mode that is called where one has manual control, acro?
Now it only occasionally starts tilting one way or the other but overall it flies well enough, i do a few laps around my chosen area.
When i come back to land i turn on level mode and the quad flips upside down for its landing, no damage but annoying.
Why did this behavior start with dRonin? Is there a way to solve this or can i export the PIDs from dRonin to cleanflight or betaflight get the the benefit of the nice tune but with a firmware that doesnt drift?
(i put that cam up top yesterday because it doesn fit in the frame, ran one of those itsy bitsy mini cams but i couldnt see ANY ground details on my last flight because i was using a screen mounted to my Tx instead of my quanum v2 box headset thing, i think not having everything else blocked out made it harder to see detail so i moved this better cam onto this 160 from my 210 quad.)
