^Eh close enough. It's called a variometer, and it attaches to a bottle like device via a tube. In gliders, you don't have a source of power so it works by air pressure. It takes longer for the pressure to change in the bottle then it does outside, so the pressure differences tells you how fast, in knots, you are ascending or descending.
^Yes, but don't you think that that's what the point of the turns is? An F1 driver can experience as much as 5 G's in a turn. This "coaster" is designed to provide it's riders with the same experience an F1 driver has. Granted these won't be 5 G lateral turns, their intent is to show what an F1 driver goes through.
Please stop asking this question over and over again, it has already been answered to you multiple times. You have been PM'd my two moderators including myself. This is your final warning.
And that Malibu has an absolutely terrible body kit. It probably puts more drag on it then anything.
Just get an eBay turbo kit, wait until it kills your car, then buy something that isn't domestic.
^Close, but not close enough. Not used for crane.
EDIT: Actually I'll give it to you. It's a tow line release mechanism for a tow plane. It mounts to the tow plane so in the event of a emergency it can release the glider (such as when the glider is unable to release).
