Visible airscrew disc

[swift]

Today I was flying as passenger with a friend in an ultralight aircraft and I had to make following observations:

1) The airscrew disk is, when running, invisible, and my guess is that the rpms are lower than what we have in Clod

2) The reflexion from the sun (heading East during evening hours ~6 p.m.) was very limited and basivally only a thin light bent line. The reflexion in the game is completely exagerated. The airscrew disk is still not visible or barely visible at best apart from the very thin reflexion line. Knowing that the blades were painted with a non reflective colour on our warbirds I guess the reflexions should be even less.
