Auto Credit Based on mario3154's Fast Challenge
          
        
          My entry into the  Fast Challenge by 206 mario3154.
#1 Activates the VTOL engines.
#2 Activates the two main engines.
VTOL down tilts the VTOL engines into forward propulsion.
My advice is to take off using the main engines and then rotate the VTOL engines down and activate #1. Reverse this to land.
With all engines forward it will hit 760 at 80,000 feet.  
Experiment with using the VTOL engines with the main engines for STOL.

Good job. :D I got just over 730mph @ 80k ft, and you get extra points for making it float!
