On my Alien I use full KISS setup with Lumenier 2306 2350kv motors. My Gremlin its the Femto controller on Beta flight with bullet esc's and the 1104 emax motors. For my Versa copter its a clone SPF3 running clean flight on Bl heli 30 amp esc's with emax 2204 2300 and for my 100 mph build I am working on Its a Kiss FC, soon to have Spedix 45a esc with Emax white top 2306 2400 kv motors and that will run Kiss. May change FC's later depending how that mix interacts.
