This article is part 4 about the plan to completely recreate the Police Spinner’s transformation from running form to flying form.
Transformation of the rear nozzle and rear bumper
Previously, I have completed to integrate the gimmicks of retraction of the front wheels ,moving the tire covers and retracting the front lights into the Police Spinner 3D model.
This time I will try to make a gimmick of transformation of the rear nozzle and rear bumper.
In the planning stage of the film, the rear nozzle of the Police Spinner was retracted inside the body when in running form. And the rear bumper raised up to cover the nozzle.
But you can only see the nozzle and the bumper in the flight form in the full-scale prop in the film.
However, there were some miniature props with the nozzle retracted and the rear bumper raised.
You can see the nozzle and bumper fixed in flight form.
Please read the blog of the late Mr. NYzeki, a leading “Blade Runner” researcher, for more details about transformation of the rear nozzle and rear bumper.

How does the rear bumper move?
Now, I have one question. How does the rear bumper move to cover the rear nozzle?
I thought that the bumper would cover the nozzle by changing its angle based on the edge of the body side (A mode).
However, there is also the possibility of the bumper itself moving up and down (B mode).
Here is the blue print of the Police Spinner.
If you look at the shape of the bumper on the blue print, you can see that the bumper has to move in B mode to match the shape of the body.
Because of the shape of the bumper, you can see that the bumper has to move in B mode to match the shape of the body
However, if you look at the bumper of the full-scale prop, you can see that it is not made according to the blue print. In the case of the bumper shape of the full-scale prop, it will not match the shape of the body side unless it is moved in the A mode.
In other words, whether to use A mode or B mode for the bumper moving method means whether to adopt the bumper shape of the blue print or the full-scale prop.
Which bumper shape will I adopt?
See the result next time!
