How to set RotationRate by casting from LevelBP

Hi! I am trying to cast the Rotation Rate variable from the LevelBP to my BP-actor Neurad, following several tutorials. In the level, I have positioned 3 wheels that have been spawned from Neurad.

The idea is that each time the Wheels event happens, a randomly chosen wheel should change its Rotation Rate randomly. Unfortunately, the three wheels do not change from their initial Rotation Rate which has been set in the constructor script of Neurad.

Any hint would be super super super welcome.

Have finally solved this. Had to create the function SuperTurn in Neurad and call this from the levelBP.
