MMp is a great esc,but MMp,Spektrum and Savox servo don't get along !! I run MMp and Savox and a 4 pole motor on my Scte 4x4 with a glitch buster and its flawless.If you run a CC BEC will be for sure to be over kill but will cure all glitghes problems.
To me,I like the MMp cuz its small,light and easy to adjust.I even sun it on my Losi 8ight paired wtih Tekin T8 1900 kv without any cap or bec and run on 4s with no issues.Get a castle link for sure...make your life a little easier !
Good luck .
