BEC vs Rx pack?

[Sammus]

Any way (apart from what brian mentioned) to stop the ccbec causing glitching? Is there anything wrong with the placement in this pic? I've had some shocking glitching issues in this car (and my rustler when I had a the bec in it. Revo is fine). Is that a little too close to the Rx perhaps?

All that being said right now I am running my MM in my XXXT. The set up is

...Mamba Max w/ latest FW, no fan yet. (9v c/o and factory defaults)
...TRX Velion 3500kv BL motor, no heat sink/fan.
...FM radio. (my 8T has the Spectrum)
...(2) 11.1v /3s /2200mAh /25-30C Li-Po's (Parallel for 4400mAh.)
...86t spur/19t pinion.
...sans wheelie bar. (has more wear on lid than tires)
...2.2 Yakahamas. (all arround)

I do not presently use a BEC or Rx pack, am I taxing my servo?
