Thanks everyone for ur opinion.
I have one question though, so in the video is it mentioned that how fast the airplane will be going depends on 2 factors:
1. pitch or how much air the propeller grabs
2. the rpm or how fast the propeller rotates.
theoretically more pitch and more rpm combined will make the airplane go faster
This is what I don't understand, in the constant speed propeller take off run, doesn't a fine pitch counteracts the high rpm? intuitively for me, if the pitch is fine then it doesn't really matter much how fast the propeller spins anymore because the prop doesn't get much air anyways??
Can someone point me in the right direction?
