3 Dec 2018

Today is the 3D day, and I want to share with you some secrets of the new particle system in Xplane11.30. Hope you can modify the particles of your favorite planes.


12 Dec 2018

After the release of the plane, we continue working (and still we are) for releasing better stuff for free for our costummers. Here you will see the different avionics you can choose from, and the option to fly in the right side of the cockpit as the 90% Siai Marchetti are.


13 Dec 2018

This one is really cool! and it is an idea that I had long ago. We all make flights and then if we have a maintenance system as REP or other you could have, if you favorite plane simulate it, when you have a failure of something, you just click "fix" and it will be fixed inmediatelly. 
This is not true in real life. Fixing needs time. And need money.
We introduce you the economic-mechanic feature in the Siai Marchetti thanks to Simcoders. Still is under development but now is on Beta, so soon you will be able to have fun with it. 
Here there is a video making the presentation but in Spanish. Soon I will make another one with more advance features en English.
