Hi folks,
I've been flying some of the various flavors of 109s, most recently a K-4 vs the huge buff mission that the rooks put together. Running a K-4 up to 32K, I just couldn't help the feeling that something was lacking. I dug out my 109 books, and over the course of reading up on the K-4 I came upon a notation that the K-4s were equipped with a new wide-bladed VDM-12159 prop. I checked out some of the pictures and you can see the difference between the wide-blade props and the standard props on other 109s. Of course I then checked all the 109s in the hanger, and they (including the K-4) seem to have the same "standard" prop.
So I must ask the questions "is our 109K-4 modeled with the right prop?" and "does it make a difference?". I'm thinking the reason they put on a wider prop is for high-altitude - they can't make a prop turn any faster, so they put on a wider blade so that they get more thrust up in the thinner air. If the AH flight model takes this into account already and it's just a "graphic" needing updating, how can I find this out? What flight testing can we do to check?
