A funny thing happened on the way to the computer:
Earlier this evening, I was testing full power dives with the B-25C from 35,000 feet. Nevermind that the plane can't get that high. Initial tests showed 740+ mph TAS and dropping slightly before collision with terrain.
I did my changes to the AIR file and retested. The new terminal velocity was about 550 mph which to me is reasonable. I then did a check to make sure that the maximum level speed had not changed as a result. 313 mph at 12,500 feet. Nothing changed.
I then throttled back to see if I could reproduce the cruise output from the SEFC I found on the B-25C. Power was too high as was fuel consumption. The family had to go out, so I left the plane cruising and went out. Several hours later, I came back to the machine and the B-25 had bellied in on the ocean (which is landable). Total distance flown was somewhere around 150-180 miles. I haven't done the exact math to be sure. I guess trim settings are pretty neutral....

~S~ Ivan,
I am sure smilo will say that is close enough for him.

How Things have Changed
Hello All,
I was doing a search earlier today and came across this thread.
I did not find what I was looking for, but the content was still interesting.
So many things have changed since the last post in this thread.
A few of the old timers are still here. Some folks were just passing through.
Some of the old folks have left but hopefully not gone from this world
The Little Girl who wanted me to add Smileys to one of the posts is now on a college visit.
She will graduate high school this year and go off to college in the Fall.
My projects described here have evolved very little though.
The B-25C Mitchell has finally gotten a paint job and is now about to get some custom built Gauges for its instrument panel.
It is progressing very slowly toward its release.
There have been many other intervening projects that were not even a thought back then that have gone the full cycle from concept to release.
I now know how to do more things and perhaps because of that, projects take longer to complete and I am often less satisfied with the results.
One of the unfortunate things about being in the CFS Forums is that screenshots tend to disappear with regularity.
Here are a few screenshots that illustrate some of the things that were described in the old posts.
Some things have changed. These have pretty much stayed the same.
