After I built Pirate Ship Ride last year, I've just completed my new project - Free Fall Tower!
I always want to construct a minifigure scale thrill ride and make it fully automated model without any manual control or mindstome programming.
Spec of the Free Fall Tower:
Maximum capcity: 12 minifigures
Length: 32 x 32 Studs (not include motor and gear box)
Structural Height : 65 cm
Drop Height: 54 cm
How it works
Gear Box serves 3 main functions:
1) Generating pull power
It will pull rope which connected passenger car so the car can be lifted up.
2) Looping 2 gear modes
First "pull mode" & Second "neutral mode". gear box will keep looping between two modes in a fixed time period. Pull mode will lift up the car and neutral mode will stop giving pull power so the car will drop.
3) Reducing drop speed
The main axle connects to a high scale gear. When the car drop, the main axle will make the high scale gear spin really fast and it will generate a reverse force to the main axle for reducing the main axle spin speed. As a result, the drop will slow down. (Just imagine you are playing beyblade)
I've submitted it to LEGO IDEAS, if you like my work, please vote:
