Of course not, but it's not just about weight. It's about weight bias. Out of the box with a 550 motor and a stick pack the sc10 has a 42%/58% front/rear bias. This is in stark contrast to most 4wd rc cars. Most are much closer to 50/50. My 8th scale buggy is 48/52. This is the a big reason why saddle packs are used: moving the weight forward. There is only so much mass that can me moved on the sc10 and since weight is typically added anyways most people put it behind the front servo or in the front left corner if they are still running a stick pack.
