i have been flighting for 2 years with my integral using the following settings in the ESC (spin 99, motor Axi 5325).
I realized that brake runs when there is in idle status (0 rpm). Initial brake starts braking motor to desired % and for an smooth braking a second brake takes the control after few miliseconds.
In my opinion: excesive brake set up in negative, when you try to do a flight with homogeneous speed. Your flight style determines your esc settings. American flight style is faster than european, so downlines cant be slower than the rest of condition flight... is just an example.
try flight with the setup i attach
