I did not create the topic to discuss the propellers for the hurricane.
but to discuss about something much more important, which is the existence of a single flight model.

again, your choice of word is confusing. The i-16 has a Flight Model and the B-29 has a Flight Model or FM. Are you suggesting they be the same FM?
I do not want my I-16 to fly like a B-29. I prefer them to have different FM's
