Apologies for  the perennial newbie bleating about PID's..

I have watched literally hours by the truckload of youTube vids giving demo's of PID tuning.  I see one guy doing wonders  with  the  quad on a string - he  gets it to tilt and it stays there.   I have been up and down the scales in increments - up ...then  back down again. I can get to the oscillation wobble - not to severe... but  I can never  get the fabled "Locked in"  state. I ended up  erasing and  reloading  3 CC3D Evo, 1 CC3D Atom and 1 Revo ( or Revolution as BangGood call it)

I know its pointless asking for examples of PIDs on 450 frames - 2212 - 920kv  - 30a ESCs linear because it is different on each machine..so I suppose my question should be  - what criteria decides the default settings in LP ?

PID default are set for most of case user can hover.
This default can't matches all frames size.

Attached numbers for a DJI450 frame, 4s and 8*4.5 pros... pretty close to defaults.

You can use the EasyTune feature or the OPTune but need at least one knob in your radio.

That the contrary, the "Revo" doesn't exist... Chinese invention.
