Dear fellow simmers,<o:p></o:p>
<o:p> </o:p>
Andreas Becker, who gave us the Heinkel P.1079A night fighter and the Driessen D.<st1:stockticker>III</st1:stockticker> flying wing airliner, was working on a Junkers D.I all-metal monoplane World War One fighter for both FS9 and FSX. The (freeware) aircraft is almost finished, but due to personal circumstances Andreas cannot conclude this project. He has asked me to make the plane and necessary files available to anyone who is interested in putting the last touches to the aircraft. These last touches include:<o:p></o:p>
- tweaking the airfile<o:p></o:p>
- Modifying the windscreen<o:p></o:p>
- finishing some details on the VC<o:p></o:p>
- Correcting some skin issues.<o:p></o:p>
- Any other improvements that pop up.<o:p></o:p>
<o:p> </o:p>
The aircraft is made in FSDS 3.0 (so not in Gmax). As is apparent from the accompanying screenshots the model is almost finished. If anyone is interested, just send me a PM. We can discuss by email or by telephone how to proceed. I have a lot of information on the D.I that I can make available.<o:p></o:p>
<o:p> </o:p>
Best regards,<o:p></o:p>

Hi, I don't know anything about modelling but I'd be happy to pitch in on any texture work.

Regards,

Hello Sascha,<o:p></o:p>
<o:p> </o:p>
That is very good news, thank you for your offer. Can you PM me a mail address where I can send material to? Or even better: a postal address that I can send a CD to? I have quite a lot of material.
 
The D.I is now available in the Warbirds library. If anyone wants to further improve the flight model, you are welcome!
 
Hard to improve on damned-near perfection...a little tweaking can be done but not too much! AWESOME release Amigo. Everything I read said that the D.I was a handful to fly. The handling of this aircraft seems reasonably close to what I would a imagine the real thing would handle like.

Stickshaker.
Just curiosity but is the flight model still the one i had started for it?? I had a rather huge breakdown and couldnt continue any more but i'm hoping i at least did ok. I'm thinking i'm in a place where i could probably finish it now as well..

D.1 flight model uploaded..

ok, so I just uploaded the last version of the flight model i worked on for this plane. It is still in pre release condition at this point and has training wheels ( steering ) attached. there are no brakes and the til skid has to be used. Landing speed is still quite high as the lift and drag have not yet been balanced in this version. If you people wish, as I said i will be happy to continue from this point and finish this project, but if you do not want me working on it I cant blame you there either.. Let me know..

Hello Pam,
So glad that you are ‘on line’ again! I mailed you several times but in the end we felt we had to move on. Yes, if you want to help making the FM better, excellent! It is your FM but I tuned it a bit. Just mail me and let me know how you want to proceed.

HANS!!!! :) :) ..you got a deal, and no worries.. I was flying it earlier and looking it over. There's a buncha things i left out of balance so i'll be working on those first. bear with me. I cant work as quickly as i used too but that also allows me the opportunity to be more thorough. Landing speed seems a bit high as does take off speed. The D.1 had brakes although they were primitive an I need to find out if they were grabby or ineffective.. Over the net couple of months i hope to slowly jockey it towards a more accurate and original type of flight characteristic. Not sure f my words here. forgive me.. but yes, happy to be on it again. will send email in the net day or so. Have a lot on my plate for today and tonight but should have time to think tomorrow ( i hope ) or Tuesday..

Hi Pam.
One day at at a time please, we can wait.
:encouragement:
 
Pam the way you recommended landing this aircraft was exactly what I did because it did not have brakes on the original aircraft...at least the prototype. Not many of these made it to the German front lines as they were not the performer they hoped it would be.

they have a tendency to nose down in a bank beyond what you expect.. Georing relegated them to balloon busting.. he hated the plane..
Oh on the brakes, we had a bit of confusion there too but we got to look real close at the wheels and sure enough theres brake lines going to them. I dont know what kind of brakes they were or where they put them but the lines are there.. I left the brake etremely primitive and not as effective as they could be, but i did so on purpose. no i have to get the landing speed down to fourty mile per hour with minimal ground effects..
 
So, over the last couple days I've done a lot with this flight model: too many details to go into here, and i just maile it off to Hans for testing and approval. I do not believe it is final yet, but its at the stage where i am no longer looking at making gross changes, but rather am focusing on minute changes here and there to draw the plane into what is perhaps a much closer representation of the aircraft.
I say much closer representation because frankly, theres little to no useable data for a flight modeler out there. theres mostly impressions and pilot reports but nothing definitive. As a comparison, i've also been studying the Junkers CR-1 which was a two seater version of this plain. I merely have to scale what we know about it ( not much ) to a single seat level.

Over all, the plane is becoming a wonderful handful, if there is any such thing. It oes want to go to the left on acceleration, but the tail skid in the back acts as a sort of anchor and keeps it fairly straight. Throttle control has become a real thing. too much and your running the engine too hard, too little and you lose altitude.

Its shaping up into a fine little plane and i do hope Hans likes what he sees so far. Its been a while for me and i'm just a little rusty so we'll see how it goes..

Yeahh, the German high command really didnt like the monoplane with metal. the previous monoplanes they encountered made by the French were easy to shoot down. Goering flat out said the D.1 wasnt good for anything more than balloon busting which is where the plane became relegated too. The CR-1 which was the D.1s two seat version made some impact, but not much.. Old man Junkers really didnt care though. His eyes were on inter-continental passenger service, and the D.1 and other planes were merely stepping stones to realize his dream. Sadly the German government confiscated Mr Junkers factories in 1936 and began using them to make dive bombers like the JU-88.
 
It wasn't for nothing Herr Junker's WW.I corrugated sheet monoplanes were known as 'Tin Donkeys', albeit the few combat reports (mostly referring to the J.1) made by allied pilots confirmed that it was bloody hard to make a dent on, let alone shoot down.
Very few, if any of the D.1 fighters appear to have reached the Front.
Just as a matter of interest, I looked through 30+/- years worth of 'Cross and Cockade', and more copies of 'Windsock' than I knew I owned.
Plenty of speculation but SFA facts.

Thats a LOT of magazines ::lol:; I envy you.. But yeah, this time I'm being made to prove my own words and make the plane fly by nothing kore that what it can tell me by just sitting there.. Its got good wide wings with a hell of a curvature to them, and a nice narrow body but an underpowered motor. Its a conundrum an even more so because its a standard design for canvas but it uses metal. Mr. Junkers we know now was a bloody genius, but back then i would have sworn he was nuttier than a fruitcake.
 
I just received Pam's new FM - much appreciated, and the changes should make a real difference - and will test it in the coming few days. Be back soon!
