I am currently using FlightGear version V3.4 Stable. I’ve been waiting for V3.6, but it has been迟迟不来. So I went to the official website and checked http://wiki.flightgear.org/Portal:Developer. It says Next release: 3.6 (-69 days from now). I still have to wait for over two months.

Left with no choice, I went to http://download.flightgear.org/builds/nightly/ to download 3.7 and give it a try. I found it runs quite smoothly. The c172p (detailed) I installed previously couldn’t work on 3.4, but it’s actually quite good on the 3.7 test build. The aerodynamics feel more realistic than before. Just a small recommendation.

Done.
