Right Engine Gear (Metal Ball)
Spin Gear: Right Engine Gear (Metal Ball)
Engine Gear does nothing of any use, at high RPM it just causes slightly more aggressive movement, at low RPM it causes instability.
While remarkably heavy - heavier than a Heavy Metal Core in Neo Casings, it is let down by Base availability and tip shape.
The Metal Ball tip and its surrounds skip over the Tornado Ridge very easily, giving it poor defense and recoil control.
Stability is too poor for Stamina (not to mention being heavy and centrally-distributed) and not mobile enough for Attack.
Not a useful part.
