To take an example, with all the respect to Xray, the T3'11 made a error with his center position servo. It was designed for Lipo, but even with a Lipo (Vs Nimh), the servo corner is already the corner with a lack of weight, and I can nearly be sure that the change on the T3'12 has nothing with the steering system by itself, but with the weight of this corner. The servo is less in the center, and more on the front, which even allow you to put the ESC more on the front if you want (I did it and it seems to work, and saw that Lemieux did it on his car some months ago).
If Xray wanted, they could have kept the T3'11 system, and just fix the turnbuckle coming from the servo on a different point (it was near the rotating point of the system, and needed to be a bit out).
So we can say that the latest Xray car is more balanced, but that the previous one (still a recent car) was not a good balanced car.

thats very clean. is that a photon ex?
A normal servo is 50g, and less than 40g for a low profile.
An ESC is 40g without cap, fan and wire, and the total can goes up to 100g
Only the Receiver weights nearly nothing
A shorty Lipo + Servo = 200 + 40
On the other side = motor + esc + receiver = 180 + 40 + 10 = 230 and you have to add cap, fan (and maybe one for the motor) and wires
