I'm just returning to Flight Simulator after a few years off. The lastest version I own is FS2000 Professional.
I recently downloaded the FSX beta, and the Mooney Bravo seems to have quite a bit less power than it did in FS2000.
Doing a by the book cruise climb, with 34" MP and 2400 RPM, I could maintain 120 KIAS and 800-900 feet per minute to well over 10,000 feet. In the FSX beta, I can barely keep 120 knots climbing 500 fpm at like 4000 feet. What's the deal? Is the FS2000 model inaccurate? Or did they mess something up in the FSX beta version that will be fixed in the final?
