Wraith steering servo twitches when crawling

[Blinkfan5150]

Hi guys first run with my wraith Tekin Rs gen 2, brushed 35tHH, Savox titanium servo, 3s, underdrive setup for crawling. As I was crawling and going over huge rocks I noticed when tires weren't straight, and hung up on a rock, the esc didn't like it. If let too long the front tires began to twitch AND ESC would chime twice. Once tires straightened out esc would chime again and wouldn't move for 5 seconds AS IF THE ESC RESET. Did this a lot. Is this a safety device on my esc so the servo doesn't overheat? Do I need a BEC? Thought Tekin Rs have internal BEC. Do I need a glitch buster? Do I need to program the esc setting differently?
Thanks guys.

And my steering servo is a little noisy as you can hear. Here's the video, is this normal?

Should I try adjusting steering settings on my remote?

Yes Castle seems to be the best choice so far.
Maybe I need a Tekin Hotwire to program the esc BEC.
I'll order the Hotwire and try and program and if it's junk I'm gonna install the castle. Thank you very much.
