I recently purchased a CC BEC for my rock crawler. I am running a Savox servo and adjusted my BEC with the castle link to 6.0v, to get maximum torque from my servo. I am wondering if I am in for a world of hurt if I try to step up the voltage maybe .3-.5v for maybe a little more torque.

i run analog servos in my crawler (hitec 985 front steering, 645 rear steer and old 605 for dig) with a castle bec set at 6.7 volts. my reasoning behind that a nitro car runs a 5s nimh pack, and when fully charged they put out over 7 volts nominal, and i found under load to be around 6.7-6.8 volts. i figure if servos dont cook themselves in nitro stuff, running the slightly higher voltage from the bec is fine. ive been running my crawler like that for several years, never had any issues.

I run most of my 6v servos at 7.4v without any issues. Savox, sanwa, KO all ok. Just perhaps expect a slightly shorter usable life however to be honest I've not had any issues. It may also invalidate any warranty you have on the servo.
