Iv never tuned any of my quads not sure if this is a good thing or bad 
Iv tried a couple of the pre sets in BF but didnt go to well hence I might start researching how to do it myself…
Does anyone ells tune theirs ?? and what are the pit falls you have come across??
Nope… not me, I just run BF defaults…
The bf tune is pretty safe.
In my opinion, the presets are for really solid tight off the shelf frames.
And, only my opinion again, if you go up a cell count, reduce the pd. If it wobbles, its too high.
I just have a throttle limit…
Do you have a throttle curve? I’ve noticed a gradual p wobble increasing with throttle.
I’ll check tomorrow.
Me?
I just have a hard limit on the throttle on the PID page, 66% when using a 6S, 80% when using a 5S. The motors are for 2555KV for 4S.
I’ve found the higher the spec of the quad the more tuning is required. As an example my Diatone Taycan flew bloody awful with the default BF script, as did my iFlight Titan. My cheap and cheerful Eachine Tyro kits were pretty much dialled in after the build, and needed next to no tweaking.
What quad is it youre having issues with Nick? Ive not tuned any of my quad yet (it looks pretty complicated to do it properly)
I built up a quad from bits and pieces, the star parts were a set of scorpion motors. That used a scorpion commander ESC and I did tweak that a little.
TBH it did have a tad more power than it probably needed, the vertical climb rate was vicious and the roll rate was far too high but it was fun in a crashy way 
None really Steve just thought it would be an idea to learn how to tune the, I agree with you it looks a might complicated. But that said it would be nice to see if tuning any of them would make a difference to how they perform…
To be honest with you, if theyre bnf quads I would stick to the manufacturers factory tune especially if youre not having any issues with them. Self builds would probably benefit from some tuning but the betaflight defaults are pretty good for most normal builds. If you do decide to have a go at tuning I would definitely take a full backup first, that way you can always go back to where you started if it goes badly. Just be aware that its possible to take a perfectly good working quad to something un-flyable or even worse have a complete flyaway if done incorrectly
I’d agree with Steve with regards to the pid’s.
But do mess about with rates to suit you. If you do a flip and are always coming out of it to early, increase you’re pitch rates etc.
Adjusting the rates curve gives you…
At point A - more or less smooth micro adjustments
At point B - the main roll / pitch spin rate
At point C - full stick deflection rate.
Racers tend to have a straight line, freestylers will have a curve like the one shown. Its all preference and you should try it on a ‘rates tuning day’
A sim will let you mess about with rates too.
Also, I’ve been trying out throttle curves and quite like a 0.75 at 1300. Though I need to tweak it a little.
It depends what you fly. Most BNF/RTF quads, just ignore them and fly. Throttle scale/limit is nice and gives better throttle resolution. Limiting motors can be good if you are a beginner flying a flighty 2S whoop. Same for Angle mode tilt angle (try 30 degree if starting out). I don’t touch PID on BNF/RTF, they usually come tuned from the factory (on some level).
On self built quads, you will probably have to tune it. Default settings are ok, but not brilliant. You can try a preset if you have built something fairly mainstream. If it isn’t though, well you will need to tune it. But I am not an expert by any means.
I always have to adjust my rolls as I come out 2 early but just thought that was me hence Ill give the above a go
