An oddd request
Hello
I have an idea that i would like your opinion on.
I currently have a jett 50 FIRE
i would like to do a science fair project that is interesting and id like to do it on airflow and propeller Id like to make a jig to measure thrust and bring tip speed up ABOVE the sound barrier to see if you reach a point where you will no longer produce more thrust no matter how much more power you throw at it
So my Q is what size prop would you use for it and what rpm can i use? im thinking that maybe somthing in the 11X5 would work maybe 11X4?
