I'm a graduate student using FSX for simulating a custom aircraft for my final grad project...

I'm Just using FSX for creating screen captures and sort videos of the aircraft in flight. The flight dynamics are not important with this model.

I'm just good enough to get the model in FSX from GMAX after a lot of work and trial & error but totally lack the skill of making the prop spin as well as adjusting the textures. Could somebody help with this task.

Help would be very much appreciated.
Thank you

Since my last post... I've been doing a lot of .mdl chopping and .cfg wacking... with little success.

The only thing that has worked is I took a tutorial GMAX aircraft deleted out everything except the prop and dropped in my model. I took the .mdl for GMAX and replaced it with the original.

Now this worked but the aircraft is the laird air racer tutorial and flies at 300 mph... My model is a ultralight paraglider.... It looks really stupid flying at 300 mph. So I tried messing with the .cfg file but I didn't get anywhere.

If anybody has the slow aircraft... paraglider, ultralight gmax file that has also is ready to fly in fsx I can get this to work I think... Otherwise I'm not doing to well.

An yhelp would be greatly appreciated

Hey Gradguy, I think you are trying to get something for nothing. If you use the flight dynamics from some other aircraft it is never going to be right. Down load the SDKs for the entire flight sim package and start reading. You will first of have to label all your aircraft’s parts with the right nomenclature and animate moving parts with the right number of frames, so that the game engine knows which item to move based on the users (the pilot) input. And second, you will need to measure everything and input that data into the CFG file. Imagine making an actual flying model aircraft out of balsa wood or foam and glass-fiber, you would have to make sure everything is in balance and works together. On the confuser, you are making a virtual copy of that aircraft design as it would be in the real world. You will have to have the numbers correct. One of the nice things here in flight sim is that you can make virtual prototypes. If you don’t like the roll rate, you can easily change the ailerons for example, without having to get out the exacto-knife and glue. Then when it flies the way you want, you can change your 3D model to reflect those changes. So, the SDK is your best friend, start reading.

Hey thank you for the feed back... Really!

I really respect the folks who are "into" flight sims This is serious and complicated stuff. It has elements of 3d molding, aeronautic engineering, programming, mechanics and pilot training.

For myself I came to FSX in the hopes of using its graphics "like google earth" to just simulate a real physical prototype model being built in project The purpose for FSX was to make some demonstration video clips of the project concept to help people understand the big picture. I wasn't looking for anything accurate. I Just wanted get fsx model in the air and make some slow turns while I recorded some screen captures.

It's been difficult to say the least... I can model fairly well but animation is not my cup of tea, as far as aeronautic engineering... I'm not even close to understanding it.

From a lot of trial and error I think I've got something that will work. I used the the FSX Laird Air Racer 003.gmax tutoral file to combine my model with its spinning prop. I kicked out an .mdl file and replaced the original that came with the tutorial. When I loaded the model in FSX everything looked great except the thing flew way to fast... totally unrealistic by all accounts. So tried to mess with its .cfg to see if I could slow it's speed but figured that all the settings represent real world physics and I couldn't slow and aircraft down to 20mph by simply cutting it's speed.

So finally I went looking for an aircraft that flew at the speed I needed and copied its .cfg into the Laird Air Racer folder... tweaked the name/title and tried it out.

It works... though its climb rate is a bit slow for some reason. So maybe somebody can look at that for me. But otherwise it's a lot better that what I started from.

Yeah it not accurate, and it just fudging the model... but that's all I need it to be. If somebody would like to help me tweak it I would accept any help.

Thanks again for your reply.

hi im simon i design my own aircraft for FSX i mainly design military jets like this screen shot which is my latest project

if u can send me the Gmax file i will apply some simple textures and design a Aircraft .cfg file that will suit the model you have designed

email me simon_hildrew@hotmail.co.uk

If you still need help with the textures, I'd be glad to help. Grin
