My favorite aircraft is the Hot Start Challenger 650 in X-P11/12. Pretty much haven’t used anything else since I bought it But here’s the rest of my Flight Sim interests:

MSFS: BAe146, PMDG 737, CJ4 with Working Title mods.

DCS World: F18 and A-10C II Tank Killer. Caucasus and Persian Gulf maps.

X-plane 11/12: Hot Start Challenger 650.
