Oh yeah, it oversteers easily, and was almost uncontrollable without the rear spoiler, even with the gyro turned on. The rear spoiler makes it behave a lot better though -- odd considering there's already so much weight in the back, but whatever, if it works it works.

No idea how it will behave as a 4WD car yet; still waiting for the ball diffs to show up so I can finish overhauling the car.
