Issues I've noticed

As I'm relatively new to making crafts, I noticed when making crafts that I don't check a couple of crucial things on some of my crafts. For example, the most recent craft (F-63 "SBS") I did not check for how it might fly with little to no fuel. Another issue is weight distribution and control. I will review the crafts I've produced and remove them until I've been able to fix any issues and check for any other issues I can think of (such as the case for the F-63 Evo, F-64 Tungsten, F-65 Angel, and F-67 Bullshark). If there is an issue with a craft I've produced that I may have missed, I would greatly appreciate it if you could tell me! Until next time
