Hi,Today I had an opportunity to fly the FSD Navajo and although the first impressions of the model are positive, I cannot get over both engines failure, a few minutes after the take off. Maybe I somehow overstress the engines by running them at full power but should they go off after such a short time? I tried to reduce throttle during a climb but it actually lenghten the engines lifetime by 1-2 minute so this is not the way :)What else do I do wrong and what should I do to let the engines operate during the whole flight? Of course, I set the realism setting to maximum and I am not willing to reduce it at all.I will be grateful for your help.Kind regards.

Check the documentation for the maximum manifild pressure (MAP) and the max for prop rpm. I seem to recall it was very easy to exceed the cylinder head temperature.Dale

Right out of the POH CRUISE PERFORMANCE TABLESEngine Operation - Max Continuous Limit 85%Sea Level - 20,000

Thanks, I just wanted to fly around and I didn't predict those engines cannot operate at 100% for longer than a few minutes :) Next time I'll read the POH even before test flight.But despite that, has anyone idea how to convert "inches" on knobs into percentage that is displayed in clouds on panels?Thnaks in advance for all replies.

Right out of the POH CRUISE PERFORMANCE TABLESEngine Operation - Max Continuous Limit 85%Sea Level - 20,000' 38" Map / 2500 Rpm20,000 - 22,000' 34" MAP / 2500 RPM22,000 - 25,000' 31" MAP / 2500 RPMI haven't flown this one in a while, but as I recall it's important not to exceed these limits and particularly the prop rpm... I generally use less mp and 2400 rpm without problems.DJ

Well, I succeded reliable flights when running ~2300 RPM and ~30 MAP. But last time I flew upwind and I was not satisfied with GS and I wanted to set engines to operate at maximum performance to make my flight faster. After setting RPM to 2400 and MAP to 31", after a few minutes, the engines blew off :( I understand that I should not overstress them, but still I think that following POH instructions should result in reliable engines operation.Is there any possibility to modify anything in aircraft configuration file that will result in more predictable engine life? Or maybe FSD has changed it in V2 of the Navajo? I am running V1 of the aircraft but before purchasing the new one I just want to know if it is worth buying.
