Unlike the Challenger V, the Challenger VI was built for supersonic speeds. This aircraft features a powerful mix of contra-rotating engines, powering 4 large propellers at the front. It's recorded top speed is 950 MPH, breaking the record of the Challenger V-2 by just 10 MPH. It's whole airframe and even it's engine was optimized for minimum drag. It currently holds the record for the fastest piston powered creation, and propeller powered aircraft in general.

It's shape and handling is a reminder of the old Challenger IV, incredible power but dangerous and unstable to fly. This is pretty much the apex of what you can do with pistons in this game, for now.

INSTRUCTIONS:

You want to be very gentle on the controls, mouse as joystick is recommended

(Start anywhere you want)

1. Throttle up to 1-5% for engine start.
2. Slowly throttle up to about 50% and as you throttle up slowly slide VTOL up to get thrust
3. Takeoff at about 140 MPH.

INSTRUCTIONS FOR SUPERSONIC FLIGHT:

1. Throttle up to 70%
2. Slide VTOL up even more, but remember do it slowly(you can use X and Z on your keyboard for VTOL aswell).
3. Keep flying as straight as possible, do not go any higher than 70% on the throttle when the blades are at a very high pitch angle.

When going for 950 MPH or higher, chances are the plane will explode, so be careful. You want to fly more than 950 MPH? Just climb a couple thousand feet.
