Hey Bison
Since it seems that you are doing the 3D work, here are some tips
The prop spins clockwise from the pilot's POV
The pilot's eyes are much higher


This photo was taken at around eye level as if i was sitting in the seat albeit a little to the right
The nose is clearly visible
Another thing is the startup mechanism
As we know, it uses an inertia stater so the prop doesn't turn until it's fully ran up and engaged
Some engines have similar starting animations in engine mod
Vasya also commented on my sound test vid asking for corrections and tips for the FM and I also told him these (along with some flight characteristics) as I don't know which of these go to FM coding and which is 3D modeling (i'm really dumb for these)
So I can only help like this but I do it gladly for my favorite plane

Another idea came to my mind of making a crop duster loadout with the spraying gantry under the wings (don't know its name in english) only appearing when selecting that and the fuel leak effect could be used for spraying
Of course if someone with good knowledge is willing to make this
Sorry if I seem too pushy and post too much but I'm really an enthusiast of this old legendary gal and you presenting us with the new 3D model woke up the old fire in me again hehe
