I have frequent FSX crashes with the Realair Duke. Unfortunately, this usually occurs well into flight, after an hour or so. Isn't there a log within FSX to help determine the cause?

How does this chrash look like? Blue screen or does FSX stop responding and CTD?

FSX stops responding and CTD.

Occures this only with the Duke or also with other aircrafts?

This only occurs with the Duke and RXP 530. I also start FSX with the default Cessna 172, thence a saved Duke flight.

Have You tried Duke without RXP's Garmin (with stock 500)?How about different planes with RXP530 added?

Saved flights may sometimes be corrupted. Just delete it and create a new flight.

I've tried with both saved and non-saved flights. I have not tried with the stock GPS for quite awhile; I'll try that. What makes this tricky is that the crash does not occur on every flight. Thanks for the advice.
