Default Servo glitching... HELP!!!

I've read though these threads and havn't found anything similar to what I'm experiencing.

This is what I've got...

In my LOSI MRC...

Before there was an issue

Castle Sidewinder Micro
Spek receiver
CC BEC
MG995 Servo
Losi Slider motor

everything worked awesome. I decided up upgrade my servo and motor to a HS-645MG and a Holms Hobbies 33T Mini Tourque master.

Now I have...

Castle Sidewinder Micro
Spek receiver
CC BEC
HS-645MG
Holms Hobbies 33T Mini Tourque master

The issue is that when I throttle the stearing glitches and even turns left with no responce to the stearing.

I've torn it down rewired and same issue.

I removed the BEC and ran just the servo and it's perfect, no issues. As soon as I hook up the BEC same problem. Mind you, it's wired to the BEC the same way it was with the old servo that had no issues.

If I can't fugure this out, looks like I can't run a BEC with the new servo?

Or perhaps the BEC is toast? I can't check with the old servo because that servo is toast. The gears blew out.

Any thoughts?

X2 same problem
MRC
CC bec
Insane 370 can
Hitec 645mg servo
Stock esc
Novak lipo cutoff

If you have the adjustable version of the ccbec then plug in your castle link and up the voltage to the servo until all is smooth. Mine only works good @ 7+ volts.

Yes the lights all come on and here's how it's wired.

I was wondering, I noticed there were no little yellow resistors things(I'm not sure what thay are on the new motor. Here's two pictures.

I upped the voltaget on the BEC to 6V - The servo says the operation range is 4.8v to 6v, Can I safely up the voltage to 7 without tosting the servo?

now that you mention it, I did have the voltage at 7.2V with the old servo and bumped it down to 6v with the new servo. hummmm

Now I have to soder the ends back on to change the voltage again...

Default No bec

Looks like I'm roling with out a BEC for now. it works awesome, no glitching, no stearing cutting out. Servo has tons of power with my 800AM 2S Blue Lipo.

I jus spent 30 min with my sons wood truck tied to the axle pulling it around the house loded with toys and crawling over pillows binding up the wheels to get the stearing of throttle to cut out due to lack of voltage and well, no problems. I guess friday I'll test it a motorama during testing and if all seams well, I'll leave it that way for the event. If not, looks like friday will be a late night.
