CRRCsim

Crrcsim is a model-airplane flight simulation program. Using it,

you can learn how to fly model aircraft, test new aircraft

designs, and improve your skills by practicing on your computer.

It rules! The flight model is very realistic. The flight model

parameters are calculated based on a 3D representation of the

aircraft. Stalls are properly modelled as well. Model control

is possible with your own rc transmitter, or any input device

such as joystick, mouse, keyboard ...
