I couldn't wait for 1C Maddox to get around to 1948 so I built my own Mc Donnell XF-85 to fly around in:

http://uk.youtube.com/watch?v=QcikXH_Cwfs

If any of you have FS2004/FS9 on your HDD you can try it yourself.

If you're happy with the FS9 Aircraft Container System, and think you can fly a hot-to-handle experimental jet fighter, then you will find the XF-85 zip file on my site at DPSflight.com

I created the .cfg and .air files with FSedit, plus some further post-test flight tweaking. If you're interested you will also find a copy of the gmax file (more polygons than you can shake a stick at) on my site. Some of the normals went a bit weird and skinners might not like the stretched polys.

IF YOU DON'T UNDERSTAND THE AIRCRAFT CONTAINER SYSTEM DON'T TRY THIS AT HOME.

There is no skin on the model and it will simply alias to the default Lear 45 sound and panel use the left N1 gauge.

Unzip the folder to the FS9/aircraft directory, launch the game and under select aircraft scroll to Mc Donnell.

When the sim loads, the model will bump down onto its scrape points.

Unfortunately, I can't take you up in a B-29 for the launch, so you will have to use the slew mode: centralize game controllers, hit Key_Y then F4 and slew up to 15,000 feet. Hit F2 to stop the ascent, then Key_Y again for the fright, sorry flight, of your life.

This is a very small, underpowered, swept wing jet and the flight envelope is tight. If you don't follow the guidance in the video tutorial you will loose control or break-up in flight. Be prepared to use a lot of pitch trim input.

I managed to zoom up to 33,000 feet and achieve Mach.75 in level flight.

BTW, you only have 40 lbs of fuel so it will then suddenly go all quiet and you will have to glide home the video will show you how to do it.

If you can put it down on the tarmac gently enough it will skid along the runway.

The trapeze hook will animate with Ctrl_L so my next task will be to work out how to build moving scenery (a B-29) with an inverted arrestor system.

Have fun.

DPS.

Extremely Mint work on this addon Bird! http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

And some excellent flying in the video.

Maybe have to look into this game. Really liked the XFY-1 you had worked on before also.

Again Mint work on this project... and Thank's for the preview.

Glad you like. Physics/Flight Dynamics is my strong area - not so hot at modelling. I'm hoping someone will grab the 3D, make it better and paint it.

This model is a must for future versions of IL2.

Did anyone spot the foo fighters?

Interesting.

Wil it work with FSX (MS sim noob here)?

I'm still very much an FS9 man. I think the control surface animations for FSX all have to be keyframe. I've posted the gmax model file up to my site at DPSflight.com so if you know anyone who can mod it for you you are welcome to have it.

One of my buddies has asked for a flight profile diagram for the glide approach (I thought that was the easy part of the flight) which I'm working on right now and will post in a couple of hours.

If any of you are going to try out this model, in addition to the training video above, this diagram might help

Nice model! Real over the top.

Bill Yenne ('The World Worst Aircraft') is right: that thing looks like taken from a kiddie ride or fair ride in some cheapo amusement park.

Considering it was released from a trapeze and that it was reportedly unable to rejoin the carrying plane most of the times, it really gave 'Flying Circus' a new meaning. I guess it was supposed to make enemy pilots laugh to death, otherwise I would feel very embarrassed to be seen in the cockpit of that flying 'Isetta'.

Great find, F16_Neo. I'll need to add a skid - and the second pitot tube - to my model.

I wonder if any of the XF-85s with winglets flew? I've only ever seen pics of them in static dispalys.
