I believe that it is the manufacturer's US Army descriptor.

Something like

U. S. Army B-26-B-5-MA
AIR FORCES SERIAL NO 41-22614
CREW WEIGHT 1200 LBS
USE 100 OCTANE FUEL

Wow! It just keeps getting better. I feel better having a full crew.
I had reset some of the "cameras" in the previous version and I incorporated them into the latest revision. Still baffled by CameraDefinition.9; it refers to the turret but doesn't show up while cycling the views. Got rid of the reference to the "Yoke" in the Shift windows.
Had the slow pivot problem so incorporated Milton Shupe's suggestion regarding the Yaw MOI and that took care of it. Really appreciated the re-located VSI. I played musical chairs with some of the gauges; Airspeed to Manifold Pressure to Fuel Pressure to Airspeed. I need to see that airspeed.
The only thing that seems strange is the effect produced by lowering the flaps. Instead of increased drag and lift it seems that all I'm experiencing is a downward pitch. Gives me something to look into.
I really appreciate the new control functions and once again thanks for an incredible airplane. As a matter of fact I think I'm ready to go flying.

Do you have Milton's suggestion on the YAW MOI. That is one thing that I am still struggling to eliminate and will incorporate in the next set of upgrades. I am trying to get this as realistic as possible and that is the one bothersome thing. It will help when I get to a late model version b-55 or later. BTW adding

feathering_switches = 1

to the end of

[propeller]

in the aircraft.cfg file will allow the feathering switches to work in the cockpit. I just discovered that.

it keeps getting better - fix the ground yaw problem with parking brake on

Here is a reprint on Milton's great fix in the aircraft.cfg file

A quick look at the aircraft.cfg and I see what I think is the problem. The empty weight yaw is 1/10th what it should be (typically the sum of pitch and roll values will put you in the ball park):

empty_weight_pitch_MOI=72639.00000
empty_weight_roll_MOI=80032.00000
empty_weight_yaw_MOI=14524.00000

I think a number is missing, maybe like a low order zero:
empty_weight_pitch_MOI=72639.00000
empty_weight_roll_MOI=80032.00000
empty_weight_yaw_MOI=145240.00000

Now you see that the yaw figure is in the ballpark and problem is solved for me.

Thank you for this very nice aircraft. :)
 
Hi,

Here's the modified MOI line from the aircraft.cfg:
"empty_weight_yaw_MOI=145240.00000"
He thought that perhaps a zero was dropped to the left of the decimal point.
I was doing a bit of night flying and noticed 3 blue lights in a line just forward of the vertical stabilizer. What are these?
I'm not sure what's going on here. I just scrolled down and see Milton's post addressing this. I guess this has already been answered but I'll post this anyway.
I'll certainly enable the feathering switches. I'm not sure how there used but it's just one more thing to investigate.

Re: Keeps getting better

The three blue lights were some type of night lighting from 1941 and was actually on the aircraft. It showed up in the references, pilot manuals, etc. I went to Fantasy of Flight in Florida a few years ago to see the last flying B-26A and the lighting showed up in my detailed pictures. It is also referenced in the Monogram B-26B model from many years ago.

Regarding the YAW MOI, I must have dropped a decimal point in the calculations.

For all that are interested. I had the patch uploaded to the .zip file. You can either change the following in the aircraft.cfg file

"empty_weight_yaw_MOI=145240.00000"

or just re-download the .zip.


Happy Easter
