That's my choice too, real nice servo and they last. The Savox 1256 works well too.

I've been going through this also. I tried a Savox SB2271SG (.065 / 277.0 @7.4) and it was not enough. I run the 2271 in my buggy and it was fine, but it just fell short for the truggy. I just switched it up to a SV1270TG (.11 / 487.7 @7.4)
I underestimated the weight and forces on the large spinning truggy tires. My suggestion is get the strongest servo you can with out getting too slow. I prefer very fast servos so picking a truggy servo was tough for me.

Also is this feature available in the HW xerun 150a?
From Tekin's website:
"Current Limit: Adjusts throttle response during acceleration. Low values allow less amounts of current to pass to the motor, high values alow higher amounts. Putting the slider in the full UP position disables the Current Limiter and allows full potential power of the system."
The way I explain this is when accelerating and creating high amp draw situations the current limiter puts a cap on the amp draw. This results in a softer,smoother acceleration. It does not change the throttle profile or curve, while still letting the motor and speedo to rev out to full throttle and still reaching the same top speed.
As for the HW stuff, I can't help ya there.
