Thank you very much for very useful information! It is a very good example of a double clothoid loop. I will try to build a double loop like Shockwave one.

I agree that the speed that the carts made the double loop was a little too fast. The centrifugal force can make poor minifigures pass out.

There are four solutions to fix this.

(1) Rebuild and reduce the height of the acceleration slope a bit. It still can make the double loop. But I have to redesign or shorten the remaining route. Because it may no longer have enough energy to make the climbing banked turn plus a climbing medium hill.

(2) Move the whole double loop structure to a higher position. This method no need to change the remaining route too much.

(3) Exchange with a Double clothiod loop same as Shockwave at Six Flags Over Texas. But only the second loop will be noticed slow down the carts.

(4) Lower the acceleration slope and remove the circular loop. But I have to change the project name, because it is not a double looping any more.
 
I will try every solution in stud-io model, then pick the best looking one for real bricks modification and testing.

iOS bug spotted! Unexpected animated thumbnail image bug


If you use ipad (or ios devices) to browse projects. You may have seen my project thumbnail image animated with wired black afterimage surrounding the carts. That graphic bug animation only shows on ios devices (or ipad only). On a PC or android devices it shows a still image only. I didn’t expect it to be animated on the thumbnail page, because I didn’t see any animated project thumbnail before. I have to click into a project to start the animation. Until I saw this graphic bug on an ipad. I will try to fix it in the next project edit allowed. 

It seem like the black shine bug only show up in thumbnail page and description tab. Other place looks normal.

Testing result on ipad project edit preview, black shine bug fixed but still left some afterimage. At least it looks much normal now.
