lol... I was going to guess he gunned it and twisted the frame/snapped the engine mounts and rolled the motor onto its side, but yes, I see the point.

The 'limiting factor' problem isn't confined to this hobby. Pretty much all systems that require engineering are built with the limiting factor in mind, and when the limiting factor is upgraded and suddenly *isn't* any longer, the system simply finds a new limiting factor.

So, case in point, the RC 10 drivetrain was designed with X capacity in mind, X was exceeded in this case, and the next limiting factor, well, limited.

I was particularly appreciative of grampi mentioning that his new engine produces roughly the same power as the traxx 2.5 (I didn't know this before). So the rustler, presumably, is designed to handle the add'l power and in its case, the suspension/handling is the limiting factor (you have great power that can't always be used).

Let me ask this (and I'm not trying to hijack the thread or anything), how hard it is to tune the suspension (and perhaps reinforce it w/ better parts?) vs. replacing the engine and drivetrain if you are only considering upgradability?

It seems like the suspension would require less expertise, but CAN it be tuned to improve handling? I'm just trying to get my arms around the whole nitro car package.

Thanks, and sorry grampi if i'm steering your thread away, it's not intentional!!
