An upgrade of my other droplet( http://www.simpleplanes.com/a/IT9Hsi/Droplet-2 ), improved the look. Original description: My first aircraft made with "dark technology". Used fine tune mod and override mod. This is a tribute to the author of the earliest droplet and the author of the novel The Three-Body Problem. Controls: My first aircraft made with "dark technology". Used fine tune mod and override mod. This is a tribute to the author of the earliest droplet and the author of the novel The Three-Body Problem. Controls: switch between fast mode and slow mode, both mode support normal airplane cont trol with no yaw. To switch to fast mode, accelerate over 300mph and pull (you don't need engine in fast mode); to come back to slow mode, enable airbrake (VTOL) and roll. You can land in slow mode.
