READ THE DESCRIPTION OK?
Use High Physics Settings
Ok basically the X-57 is a plane built for SPEED and altitude. It doesn't use any modded parts, and it has detachable VTOL engines instead.
Controls:
Take-Off: Full power, press 1 and your up

Flight: It has this annoying problem that it pitches down by itself. Good thing you can adjust trim with the Vtol slider, so slowly pull VTOL slider down until you feel confortable. Input 2 turns on the medium engine which lets her go above 2200mph.

Landing: Dont bother about landing gear, it has a structure under it that allows you to belly land. Do it. I recommend only the vtol engines for landing, so deactivate 2.

Tips:

1- If your Vtol engines just stop working, you probably took-off from USS-Tiny, and the detachable engines fell into the water. You still have the medium engine though.

2- You can only get to 2200 with both all engines at full power.

3- THIS IS NOT A VTOL AIRCRAFT, it's only VTOL engine powered.

Commands:
1- Detach from launching thing, necessary for take-off
2- Turn on Medium engine
6- (Don't press, I only used it to lock the engine in place) Makes the front nozzles movable and the plane unstable. Do Not Press ok?
