Under rating threshold (hideshow)
To hit the 12.5k points you'll need the top cash output for arcade; Thor Ram-jet and Hightech with full fuel will capitalize your outcome. However to do so you need to "feather" your throttle while making your way up to 200 feet. Then, tilt just slightly down so your speed is stable keep your speed between 160 and 200 (only tap the throttle when you hit the minimum, and release no higher than 200.). This'll be a slow descent. It'll be a very steady ride, but you'll make it. :) i finished it with 12,809 points.
