My Wankel, redesigned.
Test2
Smooth, fast and eco-friendly. (Only uses two fuel balls to power it.)
With fast, I want to say that it's fast between the Wankel engines group, because a spring engine can go up to 100 rad/s, and this engine max speed is 14 rad/s.
It's normal, and it would be some unusual that you find some wankel that goes up to this speed.
