been using the LRP QC2 and s9451 digital servo with my DSM pro in my M11 without any problems

(running mod, 19t, or 27t)
I just installed the worlds option kit in my ESC. no need for rx cap etc.
BUT..
i also encountered the DSM rx shutdown during full throttle with my KO hara2.1 esc when i ran mod and 19t before.. i tried to adjust the power save settings from 2.3v to 4.0v and the rx cap option, and it didnt solved it. Found out that my packs cant supply the right voltage for the RX when my mod/19t motors pulls at full throttle.

so i tried new packs and voila problem solved
