Altitude Control

Hi there,

I am a newcomer to blueprints, currently developing a game using as a base the endless runner tutorial from ue. However I was trying to implement a mechanic that the character could switch from running to flight mode. I was able to bind the change of modes to a button, however now I wanted the character to move up and down while in flight mode, I tried to use add force and impulse but with no success, also tried tweaking with the flying blueprint but with no success, any suggestions?
