After a bit of testing between 1.0.1 (stable) and this 126.96.36.199 (unstable), it looks to me like the force of all Hover Steering blocks has been increased to a whopping 400% (ish) of what it was (almost 4 times stronger)! Left: old max lift capacity. Right: new max lift capacity. They were definitely a little under-powered before. But I would have asked for an increase to 150%-200% of what they were, at most. (No more than half of the new value.) They're now so powerful that hovercraft (or sports cars) don't need any fans or thrusters to easily reach 100mph. You can fly with just them easily too. Also, a single hover steer is now way to strong to use on a small craft, sending my probe careening out of control: ...And all my hover steered helicopters (which I'm in the process of editing a video on) go totally bananas, of course: I'm posting this as a bug because @Sdarks didn't know if it was deliberate. @zanzistar - you usually balance the block values, so I'll tag you too.
