how heavy is that esc

Per their website, it weighs 47g empty, without wires or fan. Case Size(with out fan) - 32.9 x 34.6 x 21mm

SRG-HR sanwa servo anybody got pictures of how they are mounting them? I use the big servo saver and I'm not sure I could do that with this servo. thinking of getting a graphite spacer made up for it.

Dirla, I am running the X-ray saver on mine. Got it shimmed down as close to the chassis, but still "floats" on my X1218. I can get a pic later, I am at work at the moment.

I have an Xray pan car servo saver in my 1/12, and the coil spring that it used is terrible and the car would lose the trim with anything but the lightest bump. I had to tear apart another Xray medium(?) servo saver for touring car and swap the band-spring into the pan car servo saver plastic. After that it worked great... but it means I think I have $35 wrapped up in a servo saver.

That is not the servo saver. Many including me think the xray saver is the best for 1/12. A servo not centering is usually the servo.

That was not the case this time. I could move the plastic relative to the spring and it stayed there. After I swapped the coil spring for the band type spring, it fixed it.

I don't think your was built correctly then, there are no coil springs in a X-ray Servo Saver, it comes with 3 band springs for the stiff version, 4 band springs for the x-stiff. There was a old version that "may" have had a spring, but was not one you assembled, it was more like a Kimbrough, but haven't seen one of those in years.

I'm pretty sure I didn't hallucinate there being a coil spring inside of the servo saver.

Buggy Grip, but it may be too gummy on a track that uses corn syrup for traction aid. It works well on synthetic traction additives or crystal sugar, but it can pick up schmoo from syrup.
