Well I take-off from MMMY and head towards MMTC. It´s a 1 hour flight on RealAir´s SIAI Marchetti SF-260 and all is going well untill I get a little over half the distance when suddenly I start to loose manifold pressure. I also noticed a drop in fuel pressure as well and thus RPM´s. I click the auxiliary fuel pump but the RPM´s continue to drop until the engine is just about to die when suddenly, just as it started, the engine comes back to life again; full power.

I start to gain some altitude when it happened again. It went through the cycle described above like 6 or 7 times untill the engine composed itself and carried me all the way to the destination airport without a hicup.

This is the first time that this has ever happened. And I thought FSX was trouble free unless, ofcourse, you tell it to fail something in mid-flight.

Is RealAir´s SF-260 designed to fail from time to time? I´m beginning to think that perhaps REX2 had something to do with it since this is my first flight since I installed REX.

I forgot to mention that at some point my ailerons ceased to function properly. It lasted only a few seconds and then it stopped. It happened only once.

Saludos.

what altitude were you flying at, or attempting to fly at?

I was cruising at 8,500ft. I descended to 6,500ft after the first trouble.

Don't argue with idiots, they drag you down to their level and beat you with experience.

Yeap, I went straight through a snow storm.

Does RealAir simulate ice effect in the SF-260?

it should simulate it for all craft. I have NEVER experienced 'ice effect' on any craft even if i set the temp to -40F and fly at FL800 (80,000 feet AGL).

Just a thought. The RA Duke has this problem. Even though the airplane is fuel injected, FSX is still simulating Carb icing. You have to hit H and the engine comes back to life even though there is no carb, as a work around.

Apply carburator heat to a fuel injected engine? Wow, how real can it get Grin

I took a closer look a the cockpit instruments and found an "Engine alternate air" knob which is the equivalent of a carburator heat in a fuel injected engine.

I other words, the engine alternate air is for the FI engine what the carburator heat is for the carburated engine.

I clicked on that knob and no more problems.

Let that be a lesson to you!
