RE: Trial & error matching electric system
Hello Joe
Exactly what you write and others write, I try to prove or disprove .
I believe that models have a different working point - flying at different speeds with different style
I personally have difficult to establish such general things to all spectrum of options
so I want to show the work I have done on the specific model that I'm flying in the style I emphasizes (my model has a lot of dragge & it is flying very slowly ),
I want to show how different it is from the familiar general formula ,that's all .
I have a problem with assumeing that the rpm Remained constant =constant Watts? in flight?
The watts will change when the load on the propeller varies, it depends on the speed of the Air flow on the propeller .
so when ther is larger gap between the rpm & Watts can we assume it is mor eficient ?
But everything changed in flight , no one Can fly perfect ,
At least I can't
So maybe we need to use average rpm & average Watts
I have no problem providing the data
I fly the Osmose of CA is my third electric model, after an Intgrl of CARF& Beryll of OXAI
The Clubs I belong to are 50% electric F3A today
I work every day ,regardless F3A, in electric aviation
