770mph hydrofoil (weasel)

Bit finicky this one, took a while to get right. Throttle to 5% or so for manoeuvres, steer with roll control. 15% power should get you up on the foils, at about 100mph. If it starts wobbling you're screwed. Above 180mph is safe for full power. It'll flip over at the end. Have fun.

    There's a 1000mph version of this now. Much more unstable getting it up on to the foils though.

    Easier to add more info in comments than type on Android.

    Bit of a tap up on the right stick at about 100mph helps get it up on to the foils. Don't steer at speed, unless you like watching cartwheeling. Which you do, so you will.

    Tried various configurations of four engines, but ran out of patience fiddling with various foils, dead weight etc to make it work. I did manage to get one run to work with a four engine version, and saw 830mph.

    Lots of potential tweaks, now wondering why the frontal area is so big, originally had two foils mounted there, but never reduced it when I went down to one foil.
