I need someone to explain this to me.

Five updates for the Steadicam

[YB2Normal] has updated his steadicam 5 times! For those that remember the original, it allowed indie film makers to create smooth and steady video. Version 2 implemented a new gimbal based on a throttle linkage in cars. Version 3 allowed the user to easily adjust angles and weights to prevent accidentally knocking the assembly. Version 4 seems to have disappeared. And finally, version 5 updates the gimbal again using a Traxxas U-joint and redistributes the weight. What should come next? We think a handle, holding onto a threaded bolt can’t be good for your hands.
