What is up with Joe Binka's Widgeon?

[OBIO]

I will be tweaking the stock aircraft config file to get the 450hp Pratt and Whitney powered bird up to snuff....if I am lucky enough to get it right. Flight dynamics are not my strong suit, but will see what I can come up with.

Love that new skin Expat...very very sharp.

With regards to the overheating problem I think I have a set of the original gauges that I brutalised so it does not overheat. It was some hacking in the XML. It was nothing sophisticated if I remember correctly. I'll dig the bird out and give it a spin and see if I still have them.

Thanks. I have no problem anymore with the engines quitting, though the Cylinder Head Gauge is pinned all the way to the right . .

Still messing around, taking another of Michael Verlin's excellent paints in the re-release and trying some more variations. :ernae:

I have begun work on tweaking the air and config file to tweak the R-985 powered Widgeon into a stand alone bird. I am also working on the heat issue...even with the regauged panel, the cylinder head temp climbs way way high.....so I am tweaking the CHT and EGT scales in the air files to get the temps to reach a more normal level.

I'cve been following this thread for awhile and began wondering how come some of the planes I have (fer instance Bill Lyon's Tri-pacer) can be run at maxrpm and max temp without frying the engine...seems most planes are that way. I run everything at full realism and with the exception of a couple of planes have never had an engine burn up....why is that?Is there some kind of setting in the cfg that enables wear and tear and failure from overuse?

The gauges that Joe Binka (or who ever wrote them) developed are filled with xlm coding designed to make these engines go BOOM if you push them too hard. I found that by replacing all of the original gauges with the F6F and P-38 gauges ended the fragmenting engines...though the engines still run HOT. I have had a look through the config file and found nothing there to adjust how hot the engines get, how fast they get hot....but in the air file I found some sections that are specific to these parameters. I copied the sections from the air file of John Woodward's Beaver....and it is much better now.

I have spent the last few hours TRYING to get a dedicated flight dynamics set whipped up for the Pratt and Whitney 450 hp R-985 powered Widgeon.....and have not been successful. The power is there and the plane takes off like a rocket...but it over speeds like crazy and I have not been able to get that adjusted. Will keep trying....sooner or later luck will be on my side and I will find a winning combination of settings.

I'm not surprised. The radials in the S.C.A.N. 30 version of the Widgeon were 300 hp Lycoming R-680's [LINESTRIKE](Continentals?)[/LINESTRIKE] so you have 50% more power than it was designed for (actually 100% if you consider that the original inlines were 200-225 HP)

Middle, within the FS engine there are bits to enable damage, but MS chose not to unlock them. Some have found ways with gauges to do it and as the Widg. shows, they work.. with varying degrees of success. Of course, like most other things, when you make one bit work it runs the risk of messing up others.

There is another thread by teson1 around here somewhere where he discusses a gauge he's working on that will create "damage/failure" from excessive high-power operation.

Hmmm...does that mean if you activate "damage " in the cfg that perhaps
engine damage will accrue in hard or abnormal operation?

The Failures mode in Realism settings can be set to produce a "random" engine failure, or one set to occur within a time interval.. just a cludgy way of producing some drama but not based (as far as I know) on any engine mis-management you may get yourself into.

The gauge-based approach uses some of the coding within the sim to set and then recognize excessive numbers and produce a 'result'

Just for the heck of it I flew about 100 miles in the S.Pacific in the Widgeon with the P&W's with the stock vc.....I found that as long as I didn't redline it it ran fine. I took a bunch of screenies to post after I edit them to show the gauge readings. At 70% throttle I was making about 119 knots and the temp gauge was right below the red.
Now, if I max the throttles for just a few secs then it craps out. I'll try Obio's new panel and see what the diff is.

By the way, if one were to go to CalClassic's site there is a propliner tutorial that explains a lot about how radials work and altho this is not exactly an airliner, a lot of the info holds true especially regarding manifold settings, etc.

Thanks for the updated files OBIO

Haven't tried them yet but they're there as a backup incase I cook an engine.

I've experimented with engine handling in the Widgeon, and as long as the cowl flaps are fully opened before start and the throttles not run full forward , the engine temps in mine stay below the danger zone.

I've also had the engines running hard out untill they start smoking out the back and then reduced the power to lower the temps and they're fine.

Normally I run these P&W 450's the same as the Ag Cat in real life .... climb at 30" / 2000 rpm and cruise at 28" / 1800 rpm max.
