wow very cool

thx

Really stunning WIP...

Just tested VonS's new FM - it does a beautiful job of capturing the slow but steady flight qualities of the Junkers.  Click on shots for hi-res image.

[+Geezer 3,569]

VonS keeps tweaking his FM and it keeps getting better and better.  For example, the model now experiences wing vibration in certain flight conditions, just like the real aircraft in 1918!     Click shots below for hi-res images.

VonS is close to getting the Junkers to sit on the airfield correctly, while I have finished all four LODs and have made good progress on the cockpit.  Click on shots for hi-res images.

Meanwhile, I have also worked on the Pfalz D.III (not D.IIIa) and improved the the upper wing ribs.

The cockpit is more difficult than usual because of the lack of data.  Shots below show progress, plus only known photo of J.1 cockpit.  As usual, click on shot for hi-res image.

Update of the cockpit model. 

[+Geezer 3,569]

VonS is establishing new standards of research and historical accuracy with his FM.  Samples below:

 

Here's the polished data ini for the Junkers J.I. Wing vibrations are now frequent enough to be noticeable , as historical. Also successful were the altitude table entry tweaks under the engine section - that took a lot of tweaking and different variables but I've managed to "fix" things in such a way that the 200hp Daimler engine is now over-compressed at lower altitudes, as reported (see included pics) - this also gives the AI a bit less work to do when taking off.

Here are some basic stats for the engine now:

- below about 1000m/3800feet alt, use 70% throttle to reduce wing vibration, top speed at low alt. this way is around 168kph

- if run at 100% throttle below suggested height, wing vibrations are nearly constant with no great advantage in speed or climb (about 171kph, climb is around 3.5 m/s with the nice cantilever wing, nearly same climb rate as at 70% throttle at low alt)

- above 3800 feet, open throttle freely to 100% for max climb of about 2 to 2.5m/s (in the 120s and 130s kph)

- top speed around 1500m/4900 feet is about 157kph, drops off then with height; max theoretical ceiling is around 4000m/13000 feet but good luck getting there in this heavy steel crate, although the wings give nice lift, and vibration

- listen to the AI's engine management and you will notice that he's also using about 60 to 70% throttle at altitudes below about 5000 - 6000 feet, the management kicks in about 10 seconds after take off for the AI, with it using full throttle only to "unglue" itself from the ground

- also tweaked some of the manifold and oil pressure numbers under the engine section; and damage chances; now if there are too many vibrations while rolling out and gaining speed for take off, you might catch an engine fire; trick is to gently use throttle at first, get the tail up, and then accelerate smoothly before lifting off

Von S

P.S. Have scrapped the 220hp variant since the 200hp is an over-compressed job anyway, giving about 200hp at about 1400 rpm - I've limited the engine to 1600 rpm - this gives about 210-220hp from it, as historical, at full blast

Also, the cockpit as nearly done.  Click on shot for hi-res image.

Got a good start on mapping the Pfalz D.III this morning.

Nice to see !

[gambit168 27]

looks great !! love the wings

 

[+Geezer 3,569]

Today, made good progress on the D.IIIa fuselage.

Superb detailing! 

[+Geezer 3,569]

Finished mapping the D.3a.

 

[Heck 496]

Beautiful, Geezer. I have always loved this much maligned, but underrated aircraft.

[+Geezer 3,569]

Thanks.  VonS likes it too, and intends to make an exceptional FM for the model.  More shots - click to view hi-res images.

[+Geezer 3,569]

Maybe I should make the pilot look like George Peppard?

All right, as long as no one does the paint scheme...

was gonna say cant wait 2 skin it but looks like there's no need
u got it covered

I'll also release a graphics pack, with templates and the Photoshop art (with layers).  You can have a great time making new skins.  

[Heck 496]

Awesome, Geezer. The skinners will go crazy with a template. The model is fantastic.

The model is a 1/32 scale kit from Wingnuts:  http://www.wingnutwings.com/ww/productdetail?productid=3002&cat=5
