WILL REACH OVER 3600mph.
HOW-TO:
Step 1 - Pull power to 100%
Step 2 - Use group 1 to activate engines and detacher
Step 3 - Take off and pull landing gear up
Step 4 - Once lift off, have a fly and when you are bored activate group 6 which will push you above 3600mph)

- - - WARNING - - -
Rear wings will work at full control without snapping off until past 1500-1700mph. At around 3600mph only small movements but still works OK. Past 4500mph, I don't know.

- - - PLUS - - -
- Can fly higher than 475,000... YES, not 47,500 BUT 475,000.
- If more intakes are placed on the base, it will go MUCH faster
