if you use a repository you don't have to post all of these... your information is kept in the repo and the work you do is tagged to you... if someone wants to see the work you've done, they would simply search the commits for your name and there's all the work shown... you really should use a repo to store the history of the development... you don't have to do anything manually other than committing the latest changes to the repo...

Hello wkitty42

if you use a repository you don't have to post all of these... your information is kept in the repo and the work you do is tagged to you... if someone wants to see the work you've done, they would simply search the commits for your name and there's all the work shown... you really should use a repo to store the history of the development... you don't have to do anything manually other than committing the latest changes to the repo...

After reading the suggestions of kind people like D-ECHO, that invite me to upload on GIT, and dg-505 that suggest to upload on FGAddon, and now you; I realize the huge importance of having a repository, that other developers can access, to collaborate with this project. Nowaday I have from years a GIT account. But nothing is there. On the other side, I'm not clearly aware how to upload on FGAddon. I didn't take that decision yet.

By now I want to continue to post all of these here on the FlightGear Forum. Because as I already said I want to discuss here (the Forum) the decisions and the making of this Extra EA-300 aircraft. I will not change this path to get a faster result. Maybe that can be boring for you. Hope not. But I'm sure, on the long distance, all this thread will be very useful, for that new developers, that want to collaborate and contribute with FG Community; adding their piece of art, to the FlightGear Flight Simulator we love.

Regards

~Patrizio.

The Directory Models



The models directory is one of the most complex because it contains several other sub-directories necessary to give the development whole work a certain organization.

The sub-directory Effects contains all aircraft effects



The sub-directory Immat still nothing much there



The sub-directory Interior contains all the elements will go inside the cockpit.



The sub-directory Lights it contains the light effects



The sub-directory Liveries contains all other textures than default



The sub-directory Pilot contains a really new pilot for FlighGear. Actually a female character.

[D-ECHO]

Looks good!

[danielHL]

Yeah - it looks really good. I'd offer to tinker with the YaSim FDM. But sadly there's no way to collaborate...

[cobe571]

@D-ECHO

Looks good!

Thank you

@danielHL

sadly there's no way to collaborate...

That's not really true what you say... I'm still showing the entire job. When I'm done, I'll upload for sure into some repository that I have not choosed yet. You can already contribute showing the parts of code you want to add to the project into this thread.

Thank you really much.

Regards

~Patrizio.

[danielHL]

Yes, of course I could post a yasim config file here. But it would be much easier if I knew for example the 3d model origin and can overlay the yasim visualization in blender and so on... Also FDM creation involves a lot of flight testing and that's much more fun (and easier) with a visual model (as viewing reference) and not only a yellow glider and a HUD as cockpit

[cobe571]

@danielHL:

I really thank you for suggestions and good hints. I know most of the things you said. I have to repeat I have not choosed yet a repo. Every idea is really appreciated. As you know into this thread we already talk'd about using GIT and FGAddon for this purpose. A choice will come soon I think. Anyway let me time to show what I've done on these past months. I want to show every file and discuss them all, if possible. You can help this way also. I'm trying to follow a path. I want this project to be very collaborative, as possible. Not simply adding code parts. But explaining too, why we're doing a way, than another. Isn't really easy I know. Coders likes more to make things than talks about them

Regards

~Patrizio.

[wkitty42]

use github for your main development stuff... later, you can have a branch placed into FGAddon and update it as new major versions are released...

[danielHL]

For the fun of it - I made a flyable YaSim FMD. I will contribute this to the project if there is a repo and the development goal is to commit to FGAddon.

[cobe571]

@ danielHL:

I'm already developing the FDM. What I need is help - not a new FDM. At the right time I will upload to some repository I will choice. That's all!

Regards

~Patrizio.

[danielHL]

If I compare what you posted earlier with what I researched on this type - you don't even have the basic features right. The EA300 has no flaps. It has more than two tanks. It has no retractable gear. Pilot and Copilot weight are not listed. And a tandem vstab and rudder? Really? Nearly all engine and prop parameters are wrong.

And the YaSim output of that file is totally unbalanced. Lift coefficient is way too high, max thrust doesn't compare to spec, MAC and CG are out of bounds. Yes, sorry, you do need a new FDM.

[cobe571]

@danielHL

I'm glad you said that.

~Patrizio.
