Spawn Per Unit on moving PlayerPawn

I try to Spawn a Ribbon behind my moving pawn.

The problem is, that it doesn´t start spawning at the beginning when I start moving. I have to rotate many times until it works.

I already found out that it works when I set my currentforwardspeed and currentrightspeed to fixed values.

this are global variables wich are set by my axisinput events. When I set them i.e. to 1000 the ribbon spawns immediatly.
