RE: Trial & error matching electric system
Hello
All the questions originated from problems due to basic assumptions,
attempt to find the sclution I also began to understand better the problem (it's a natural process)
The problem was the Power Consumption when I fly very slowly relatively constant series of P11/F11
HACKER C5013XL
20X13 PROP received power in the 4000 MA P11 flight of 5000 it was plenty
In retrospect: not suitable for my model
It is for those who love to fly faster F3A
I got another lesson about the “big differences” between Outrunner considered less efficient
Again I found efficiency propeller is the Major dependent .
The differences between inrunner+gear 89 % to outrunner 87 % should not determine when Choose the motor fit
The best propeller suitable to the model and the motor that can turn this propeller wthe efficiency should be it .
I found my model like the propeller 22X12
This propeller should be a very big load on the motor = a lot of Power Consumption,
But it turned out well mor Economical when flying appropriate speed.
The logs wer after I let myself learn the new system on the model , understand the system and it is not the first flight after changing the system & Attempt flying at the same speed.
The fact is that the time it takes all series by the graph ,which means that almost one Variable is Tested (as far as hand-eye know how to fly precision)
