I have owned and used every surface Castle Esc since I've been in this hobby. I've ALWAYS used a Castle 10A external BEC for every application and just remove the center red wire off the ESC bypassing the internal BEC.

We all know Castle ESC's are prone to high temps, weak internal BEC power, and usually my servos are 300 oz/in. to 600 oz/in. since most of my rigs are crawlers or huge monster trucks so a separate external BEC is a must.

If I run a Cap pack do I need to run also another Castle 10A BEC? This is for a Savox SA-1230SG digital servo 500/oz in @ 6.0V on an 1/8 OFNA GTP2e on road GT basher.
