    • Josh, my apologies for missing the part 7 update ! Your doing such a great job with this my friend.. It has to be one of the most comprehensive tutorials , I have ever seen ... I never realized when you started all of this of course how involved and detailed this would be.. But your continuing to do a marvelous job with it to date ..   Brian
    • Clayton,  thanks for your last comments ! Pierre, has not started using the RRW as yet. I do think he is planning on trying it out at some point though..  But it is a rail mod that is a total replacement for the older " Maxis rail"... and its been worked on now for quite some time.. Well at least the last couple of NAM's i know. It is still currently in development, and so they keep coming up with new content all the time .. I just started using it for the first time with this new city, so i still do not know much about what you can currently do with it . But maybe after work today I can try to post some sorta comparison pic, just to give some idea what the textures look like in comparison to the old maxis rails. And i will post the pic to my CJ here, later on..
    • Chapter 3 - Basic Aerodynamics Part 1 - The Four Forces Now that we've actually flown our first flight, we can move onto some of the science-y stuff. Imagine a Boeing 747 or Airbus A380. How do these planes, often weighing over 400 tons, manage to not only stay in the air by move through the air at over 500 mph?  Imagine a fish swimming through the air and a plane flying underwater. Although fish and planes obviously are vastly different in how they move and stay afloat, the basic principles of how a fish doesn't sink to the bottom of a lake and how a plane doesn't fall back to the ground are much the same. Whether it's a fish or an airplane, there are four forces at work, like arms, holding the object in place. Lift and weight are in a continuous tug-of-war as gravity pulls the plane back down and the flow of air over the numerous airfoils create lift, holding the plane in the air. As the plane moves forward under the thrust created by the engine(s), friction with air particles creates drag, reducing forward movement.  Airfoils are devices on the aircraft intended to take advantage of air currents in order to control the aircraft. Lift: Wings and stabilizers are shaped so that air is deflected downward as it moves across and under the wing. According to the third law, this means that the plane would then rise in the opposite direction of the downward airflow. This is why a typical airplane (not counting helicopters) can't simply lift off the ground. They take off down a runway, gaining speed, increasing airflow across the wings. Then, once a point is reached where there is sufficient airflow to hold the plane in the air, elevator is applied to decrease the lift in the rear section of the aircraft, causing the nose to rise and the plane to leave the ground. One interesting thing to note is that, on its own, an airplane would eventually leave the ground on its own if enough speed were gained. However, a runway long enough for this to happen would be highly impractical. Thrust: Thrust works the same way as lift, except horizontally instead of vertically. In our aircraft, a combustion engine powers a piston which turns a propeller at the front of the plane. The propeller in this case has two blades. Think of these blades as wings that are generating lift, except horizontally. The propeller accelerates air behind the plane, and in this case, the opposite force is the forward motion of the aircraft. Thrust is necessary to counter drag as the plane moves through the air. If thrust is lost, drag will reduce the plane's speed through the air, which in turn decreases airflow across the wings, which in turn decreases lift, causing the plane to descend.   
    • @Acko, I wasn't very active in the summer so I didn't get to see this, but what I see here looks pretty interesting, I hope you are back soon with some more updates, I miss seeing you around.
