Hydrofoil on KSP 1.10
And yessss, the thingy took off. :D
Note the lack of drag, by the way.
Oukey, I thought, back to 1.7.3 so... But then I reconsidered due that
Physics easing message. This stunt is not there just because, right? And if the glitch was not in the physics engine as I thought, but on the Easing itself?
(I just reviewed my last attempt on 1.9.1 just to be sure, and there's no
Physics easing message there - but the behaviour are curiously similar!)
So I installed Vessel Mover and gave it a try.
