DeHavilland DH.86 Express by Kazunori Ito

[OleBoy]

T-Square brought this one to my attention in another topic. I figured best to start a new topic, rather than add to the DH89 topic.

T-Square says

Hey OleBoy

If you like De Havillands Ito did this one.

FS2002/FS2004 DeHavilland DH.86 Express. This was a four engined development of the D.H.84 Dragon, developed in 1933 to meet an order by the Australian QANTAS for an airliner to fly the Singapore to Australia route. A number were operated by various military services. A total of 62 were built. The DH 86 had a busy career until eight were impressed into RAAF service from late 1939. Three kind of paint examples (Imperial Airways, Qantas Airlines, for military) are included. By Kazunori Ito.

Mr Ito did a great job. It flies very nice. Has a great 2D panel and VC that's not bad either.

Add to this

Two sets of repaints for it over at the Pond - plus Garys sounds can be modded for 4 engines

Sorry The devil made me do it

Leif

BTW there is a new Express in the works dont quote me but I do believe for FSX and its not by Ito san


what I want is a Dragonfly

[T Square]

Needs a good sound file. Any suggestions ?

[harrybasset]

There is a Heron sound file at Classic British Files.

http://classicbritishfiles.com/index...ileinfo&id=448

Sounds good to me.

[T Square]

Thanks Harry! Downloading as I type.

Something I noticed about the start-up is that it takes forever to get the engines to fire. I tried adding in a bit of throttle but that made little to no difference. Are others experiencing the same?

I looked at the config file but I'm not sure what to be looking for to change.

Under engine section, increase starter torque bit by bit until you have it where you want it. :salute:

[OleBoy]

Thanks for the tip Terry. I'll play around with it.

[Z-claudius24]

Hi,

Under engine section, increase starter torque bit by bit until you have it where you want it.

Mind you .. this aircraft have not a engine or a prop chapter in aircraft.cfg
And adding those have no effects ... so they must also not be in the air file !!

The key is found in "General Engine Data". It's well-documented that Ito-san took great pains with the visual model as that was his area of interest, but was NOT an 'airfile guy'. His only desire was to have a model fly so he could enjoy the visuals and thus he cut many corners. In this case (as many other of his a/c) you find:

[GeneralEngineData]
engine_type=1

engine_type: 0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turboprop
so the reason it takes so long to "spool up" is just that - you are starting a shop-heater.

Many of us cherish every plane he has modeled, but the work required to tidy up the details, as well as respect for his wishes regarding modification tend to limit the number that have been brought up to a high level of flight dynamics accuracy.

Sorry, forgot that Ito uses turbines in all planes. I was thinking of the DH-89.

[AndyG43]

Wasn't there another DH.86 over at The Old Hangar? I seem to recall that it was a beta version, but could well be worth checking out - and maybe the FDE could be applies to Itosan's model?

[OleBoy]

Is this the one? http://www.theoldhangar.net/CLH_DH86Express.zip

[RyDraiggoch]

I think a couple of us over at the Pond played mix and match with those two Oldboy


I know Peter Watkins did a couple of repaints including a Union Airways one


Leif

[OleBoy]

This is odd. I installed the beta and tested it. I found the FDE is better so I backed up the originals from Kaz Ito's and popped the config and air file in there and loaded it up. Contact points are way off, but that wasn't my concern right now. The spooling is no longer there and the engines fire more realistically. Kaz's 86 had a 2D and no VC. But when I put the new air and config file in there, now there's a VC. Problem is, the viewpoint is from the passenger area. Once I get that figured out (if I can) it will have the same view for the 2D and VC. Here's a snap from VC view

[RyDraiggoch]

AH yes

I do remember that problem -- you can move the POV forward (Had to do the same with the Skyvan as the VC position was sitting on top of a box behind the flight deck bulkhead.


Leif

[OleBoy]

How does one go about moving the POV? Please be specific as this is new to me..lol

OB,

Go to aircraft config and find views. The first number is side to sid, the second is up and down and the thir, which you want to move foward is the front to back. Just make it a higher positive number in low increments until you are where you want to be.:ernae:

Sorry for the necro post, but it is applicable...

Did anyone ever put together a workable DH.86 that they could email me?

Mr. Ito's looks very nice externally, has a VC...all good enough for me except it has a jet flight model!!! It is screaming fast and won't stay in the air at realistic speeds, so...

just wondering if anyone has a modded version of Mr. Ito's DH.86 that I could use. I'm not real fussy (I don't care that the engines take a long time to spool up...lol) but I would like something that will cruise nicely at about 120-125 knots.

Thank you!

[Mick]

... Did anyone ever put together a workable DH.86 that they could email me? ...

I adapted the flight model from Lee Holmes' DH.86 by patching in the User Interface, Contact Points and Lights sections from the Ito plane into the Aircraft.cfg file and substituting the Holmes AIR file. I don't have the expertise to vouch for the accuracy of the Holmes flight model, but at least it's not a jet!

I've attached the flight files here. Don't forget to edit the User Interface sections if you don't have the same paints as I have.

[Kodiak]

Thanks for this, Mick!

I'll put it together this evening and see if I can get it up and running Close will be good enough for me, just so I don't feel like a jet...lol

[Kodiak]

Thank you, Mick.

I just applied your files to my DH.86 Ito installation and it flies very nicely. It holds altitude at reasonable cruise speeds and seems to handle just fine.

Mr. Ito made a very nice DH.86 model visually and it just needed some tweaks like this for a more realistic flight model.

Happy holidays!

Bill

P.S. I was also able to find the extra skin you had listed in the cfg, so I've added another skin to boot

[lemonadedrinker]

Hi,
I cheated . I like the models and found the earlier version from Bluegrass Aviation by Lee Holmes as well as Ito-san's, but I also like Fraser McKay's panels and so used the one from the Dh 104 in both versions. A bodge I know, but it is nice to fly around in, so apologies to all!
Andy.
