Gyroscopes are unreliable for engine timings -- try doing a loop-the-loop in a car powered by an engine and you'll see it'll slow down whilst upside-down until it goes backwards. A much more reliable approach is to have a ranger seeing how far away the slapper is, and using the delta of that to see whether it's going in or out.
I made one. Haha, it's one of my later ones.
What I don't like about rangers is they lag in multiplayer.

Nevertheless, a very well-made slapper engine.
