RE: Lets discuss P-Factor
DK:
Sounds like a good experiment. Try to have the incoming air at a high velocity to get as close to the real world as you can.
Let us know the results.
The presessive forces definitely exist, it's just that in a conventional prop they are much smaller than the aerodynamic. In high speed high power aerobatics precessive forces do become a factor to consider, but not in take off or normal climbs.
