Having flown alot of vintage lately, I'm getting used to monitoring CHT, carb heat etc to avoid engine failure. I know this C337 has cowl flaps controls, and what appears to be an advanced fuel mixture model. So, is it possible to get engine failure or at least damage if you push it too far or neglect the temperatures?

Too high CHT most definitely yes... damage / failure.

 

High CHTs can be a sign of a number a things including pre-ignition / detonation which can easily lead to engine failure. Pistons can be pitted or even melted.

 

A problem with the 337 was the fact the rear engine sits right behind the fuselage, rather than on the wing like a conventional twin. This results in cooling being more of an issue for the rear than the front engine.

Too high CHT most definitely yes... damage / failure.

Allright. Is this modeled in the Carenado 337? It's more interesting to manage engine temps if there are consequences.

As far as I know damage/failure isn't modeled. Also, the CHT and EGT run fairly low, same as most FSX aircraft. Getting them to expected ranges where you have to worry about mixture (EGT) or cowl flaps (CHT) requires edits to the air file.

 

According to various C337 owners, the rear engine does not have an overheating problem, if that's what you were saying, Rob.

No sir... just the fact that it isn't in the airstream like singles / twins... just something to aware of.

 

Just like you have to be more "aware" of that rear engine (monitoring instruments) as not so easily noticed if a partial failure e.g.... certainly not like a conv. twin. which will let you know w/ yaw.

 

I used to work on one based at Terry airport when I turned wrenches there... I thought it a beautiful (and interesting) plane. We called it the "school bus" as it was primarily a very nice yellow with black trim.

Having flown almost 300 hours in the real version, I can say that the rear engine does run hotter but not to the point where you have to nurse it. Different story if you forget to open the cowl flaps!!
