DC Designs Northrop P-61C Black Widow RELEASED

warchild said:
I know.. But you see, the files in the fde, follow the version and date of the fde itself. So for instance, FDE v1.0 dated 7/15/2018 has files in it dated 7/15/2018, While FDE v1.29 dated 7/30/2018 contains one file dated 7/29/2018 and one file dated 7/30/2018. The files inside the FDE are almost always in near lockstep with the FDE itself. Thats what makes you having a file dated in may that much more of a conundrum. I didnt release anything in may, unless it was a one off on the rf-61 reporter, which is a possibility, although you would see an amazing difference between the two.

Hi,
The aircraft.cfg you supplied as an update this morning, "Northrop P-61C_FDE-2.5.zip" has ( May 2018 ).

For me, even with the updates you supplied this morning it still pulls incredibly hard, thus my decision to eliminate the three realism settings. The other things I noticed (1) If I taxi below 15kts the airplane will track straight. . .above that and it gradually begins to pull. (2) Despite setting the contact point for the nosewheel to allow nosewheel steering rather than differential steering unless I taxi very slowly it will react as though differential steering is required. . .which because of my control setup means hitting the brakes to turn.

Ed!
I'm sorry to put you through this, but i need you to do two things for me and then report your experience..
1.
In the aircraft.cfg file, go to the [Propeller] section. Under that heading is an entry called "prop_sync_available". Set it to "1"

then

2.
Under [Piston Engine] find the entry titled "idle_rpm_mechanical_efficiency_scalar" and change its value to "0.689"

then give it a try and let me know. Yeah, I know it sounds absolutely insane, But i just did several tests in FSX SE and it works for me.. The theory is, those props weigh about a thousand pounds each, and if they get out of synch, one prop will become dominant providing more thrust and causing the plane to turn.
let me know if that works or if i've completely gone over the edge. Ok??
Thanks.
Pam

Loading FSX now. . .by the way, this is what my [piston_engine] section was already set to (this is your aircraft.cfg from this morning). . .

max_rpm_mechanical_efficiency_scalar=0.689 //1
idle_rpm_mechanical_efficiency_scalar=0.689 //1

It's pretty much spot on perfect in my FSX, Pam! No hard pulls in either direction on the takeoff roll. Smooth as butter with the A/P turned on climbing out at 1000 feet/Min and levels off smoothly at the desired altitude.

Happy camper time:applause: :ernaehrung004:

I will try some taxi tests later while I'm mucking around with trying to install a radar.

Thats absolutely awesome news Zippy :) :).. Thanks for letting me know..
 
I downloaded and tried it late last night and also had the problem holding it on the runway, full rudder one way and it would still turn rapidly in the other direction. Then I noticed I still had activesky/real world weather active and there was an 11 kn cross wind. I turned off activesky and reset for fair weather with no wind and was able to takeoff straight.

This morning I tried again, winds 8 kn at 240 degrees using runway 27 and could barely keep her on the runway, but was able to safely takeoff. Changed the wind to an 8 kn crosswind and there was no way I could keep it on the runway.

I hope this information helps debug things, its a great aircraft.

I was using P3D v4.3
 
No change Pam. Actually at any speed above 15kts, if there was enough area, it would do a complete circle. It requires full right rudder and braking to bring it back in line.
 
This is supposed to have quoted you.. ::sigh:: Just one more weird anomoly to deal with today..
Anywayyyy..
I can see why you made changes too things like the minimum throttle. You see, As I was telling Falcon409, those props weigh upwwards of a thousand pounds each. When you set the MOI to 35 slug pounds of force, you gave them all the weight of a cessna's prop. The engine actually has more friction on the shaft than that prop can develop, and thats why your engine dies. Your using a butterfly to pull a freight train so to speak. Now, an MOI of 135 Slugs is what is correct for the P-61B which still uses a Hamilton Standard electric prop, but its a normal prop. The props on the P-61C are paddle props and almost a full foot wider at the apex. They weigh far more than the P-61bs and require a lot more effort to overcome their inertia. What your doing has set you on a course that will at some point end up in disaster.. Trust me. I'm an expert at blindly creating disasters.. Setting the prop moi back ti 135 should give you an rpm oif 800 for idle. If it doesnt ( which I still think may be accel or SP2 related ) then go to the [Piston Engine] section, and increase the Idle mechanical efficiency. That should at least get you running.
And if this browsers weirdness ever goes away I'll be able to post quotes and converse more directly with you..

Thanks Ed.
I'm really sorry.. Let me jump back into it and see what i can see..

Hi,
Open the aircraft.cfg, at the top of the page. See screen shot.

Also from a remark made by falcon409, message # 126, where he notes a wrong texture location.
"NOTE: the texture name for "texture.791" has changed to "texture.Baremetal". Make that change to your texture folder or the Sim won't display that airplane, lol"

I think this might indicate that an older aircraft.cfg was being used and not the release version.

Killing time...

Waiting for the paint kit and the texture "pros" to start their magic.

OHHHHH.. No.. That was a notation by Dean. When he started on the P-61C he used the fde from the RF-61 as a starting point. I yanked the guts out of it leaving only the flightsim and camera entries, and put in the FDE from roberts plane. THATS why it says May 2018. Thats when he started on the P-61C. I just havent changed it because its just a notation and serves no purpose..
 
once the kit arrives I have a handful of "B" nosearts I want to throw on and, of course, one for my personal plane, which I make for every A/C once I take a liking to it :encouragement:

Yes I understand Pam, but it seems that reducing the MoI is the only way I know to make the prop slow down more quickly, having said that maybe the 0.689 efficiency scalar might have an effect corelated with values in table 509? - Something else to try. I might also light up my old 'puter & try it in FSXA which I assume Falcon is using as opposed to me using SP2.

Seems rudder authority needs a bit of tweaking with others not able to cope with a crosswind.

Interesting...... ain't it - & not only with Rowan & Martin!

Except for the fact that the sim entry is wrong...

Where??? The very top where it says may?? Everything else on that page is correct.
So, the creator of the model, decides to notate this as an rf-61C in and FDE i spent thousands of hours working on ( about 5.5 actual years ) and you wanna bust my chops for it.. You dont like it, change it to something else. Simple as that. You know why i only worked on the fde 5 years and it took 8 years to get it too you?? Its because i got tired of the absolute bullhocky like this that was happening and I left simming. I'm sorry the notation is wrong. Tell Dean.. I'm sorry the XB-35 wasnt finished. Find someone whose good with MCX and Gauges, I'm not. I go the mile and more for all of you on a daily basis because i really DO care about this community. Give me a flippin break..
 
I guess at this point a full setup description is in order:

I have been using FSX/Accel for all but one flight (I also have P3D_V4.2 but rarely fly it).
I have a CH Pro Throttle with one control so I do not have the ability to regulate individual engine settings (dual throttles)
I have a fairly new Logitech Extreme 3D Pro Joystick with twist grip (the normal throttle tab on that is mapped to Prop Axis)

Both controllers were calibrated a few days ago after I woke one morning to discover that both controllers had lost all the mapping and had been reset to default (a PITA).

I always fly with realism settings "middle of the road". Crash detection off, Engine damage off, Aircraft stress off, automixture on, gyro drift off, unlimited fuel off and so on and so forth. However for this airplane I turned all damage and stress settings on and did my level best to fly with the intent of making it home alive.

I also have a weather program (FSRealWX_Pro) which I rarely use and several REX Programs. . .also rarely used. So in fact, whenever I fly on a normal basis I have "0" wind so that is a non-factor related to the inability to control the airplane during taxi (above 15kts) or take off roll.

I do have now and actually have from the start, had a sound running in the VC with engines off, reminiscent of an old car I had as a kid that wouldn't shut off after I had removed the key. . .something we referred to as "dieseling". It's not heard from the exterior. . .only in the VC.

I think that about covers everything.
