Isn't the FDM of the C172P good ? And what about the C182 ? I'm talking about that kind of JSBSim FDM, but yes,
And finally thank you for not polluting again a post which is only there to present the new models and the updates.

you are right, I am sorry, and I'll shut up now.

Well, that being said, today, after many design errors, the Latécoère 523 arrives on FGAddon Trunk.

Hi there.

A few years ago I started an Italian model, but I had problems with 3D.....Lack of experience, lack of information etc... In short, I left it on hold . But there was an entry in my Hangar with no file to download....It made me more and more nervous. So here it is 3 days ago I started everything from scratch. And I don't know if it's the extra experience, or luck, but this time I went all the way.

So here I see present and offer you the Savoia-Marchetti S.65.

Asked by a friend on FB (he learned to fly on this plane) I couldn't refuse. So here is the PAC CT/4 Airtrainer. Hoping you like it.

Available in my hangar and on FGAddon Trunk

Merci Baranger!  Tous les avions que vous avez créés pour FG sont les meilleurs en termes de réalisme et de caractéristiques!

I've just fly this plane and it's very well made... next PAC aircraft will be a P-750 XSTOL? :lol:

However, I really enjoyed your aicraft, because they are very realistics and also all the flight features are so well represented. All of them, I prefer Tecnam aircrafts, because I know them so well and the ones you make available are truly exceptional and very realistic.
It would be nice if your Tecnam series was completed with the light-weight P2002 Sierra or Sierra Mk.2 and the P2012 Traveller, two aircraft that are highly appreciated for their simplicity and effectiveness all over the World.
If you prefer, I can collaborate in the realization, but please don't ask me too advanced programming stuff! :D

Regards, PaoloA

Well here it is, to please PaoloA, here is the Tecnam P2002 Sierra arriving in my hangar and on FGAddon Trunk :)

And after some discussion, it is possible to choose in the menu between the classic panel and the glass cockpit.

14 years ago I modeled an airplane that I never placed in FGAddon because I couldn't find enough information and detail to estimate it sufficiently advanced... The years passing and my little experience increasing j 've managed to move forward enough to finally propose it.

13 years since I started this model. But little information found. Luckily recently I have been in contact with an American museum which is restoring an identical model. Here is the first evolution of the Burnelli CBY 3

B-25 take off from carrier

Postby naplesAPF » Wed Feb 15, 2023 3:39 am

Emmanuel, thought I'd post here because i think you originally developed the B-25. Can't get the B-25 to take off from a carrier; which is a Very Important part of its WW2 history. I wish I could get it to get up enough speed to get off the end of the deck, but have been unsuccessful. Any help you could give would be greatly appreciated, to this guy who's a historian.
FYI maybe it would be helpful to know that the DHC6 plane is able to take off from a carrier.
Thank you in advance for any effort you may consider devoting to gettinng the B-25 to take off from a carrier.

The Doolittle B25's were specifically lightened to enable them to take off from a carrier.

And still, Doolitle's own plane almost went into the drink before it started climbing.

How fast do the carriers in FG go? Do they turn into the wind? And did the OP set at least a 20 kt surface wind (so that the relative wind would be >40 kt before the B-25 even started moving)?

Indeed, as StuartC points out, the Doolittle B25s were greatly lightened for this operation. Armament removed (even the tail machine guns have been replaced with wooden brooms lol). A specific FDM would have to be reworked for this. It's not impossible...I'll see. The challenge is interesting :)

Do they turn into the wind?

Yes they do turn into the wind. I was able to take off using the stock B-25. I dropped almost to the water before I had any lift and climbed back up. It was an interesting experience.

LOL. A plane scheduled to take off with 700 meters that takes off with 150 meters .... That makes a hell of a difference

The real problem is the difference between the Nimitz that we have in FG and the USS-Hornet CV-8 of 1940. 0 the time there was only one runway to land and take off using the 250 meters totally. This is not the case on the Nimitz.

The ideal would be to be able to choose the starting point on the aircraft carrier. Positioned around the rear at the level of the attachment cables.

It is impressive that they managed, but the 150m vs 700m comparison doesn't fully apply. I don't know the actual speeds, but if you assume combined carrier speed + wind of 40 kt and lightened planes, then they would have been about halfway to liftoff speed before they even started rolling.
