I use this servo in my SC10. Now, I don't have that speed controller, but I run a Spektrum radio and ran a Mamba Max Pro last year. The Mamba esc has a notoriously weak bec and is well known for causing servo glitching, even more so when paired with a Spektrum radio. I have not had one single issue with brown outs or servo glitching. The 6040 is a fantastic servo and can not be beat for the money. Check out the reviews at Amainhobbies. Nobody can give you an iron clad guarantee that you will not need a glitch buster or capacitor, but I'd be very surprised if you do.
