Loop cut and slide in Blender 2.81 and 2.82 (for thruster)
In the Blender 2.81 and 2.82 you can't add more loops with the scroll wheel anymore with hitting CTRL+R or selecting the icon( :/) . But there is a workaround - In order to do it - Select the edge that suppose to get cut , right click, choose "Loop cut and slide" and then you will get the "old" functionality portrayed in the video.

All the best,
