Run ok for a while than program start to crash

Excellent program

Frankly, this program sucks.

Bottom line: if you're doing IFR training, this program is extremely useful for developing core instrument skills, especially the scan, radial intercepts, and VOR tracking

The program may work in some aircraft where the settings can cover up for the lack of precision in the basic program, but the problems show up in tailwheel and sport aircraft where control Inputs and responses need to be precise. .
