I made a better simulation for the K-39 kit with the paper fins (no distortion), I also attached the simulation file that includes both fin sets (paper and plastic).

I am working on the Estes Saturn V K-36 simulation, I hope to include as much detail as possible, the Saturn V .rkt file at rocketreviews.com is very basic, it does not even take into account the fin fairings and escape tower.
