I enter the data of the actual plane -span, length, weight, motor, ESC-, rigging it for 3D, and then run the EZ Optimizer. It returns a 2S 3200 mah battery with a 4.5 x 4.5 propeller. This makes no sense.
Hi. When it comes to the calculator's optimizer, it is an overachiever. I will examine every combination of power system component that it can get its hands on. A lot of these combinations will not make any sense to you, but it does not know any better.
The key to getting the type of result that you are looking for is to use the component filters. This is the button labelled "Off" next to the component name. If two cell battery packs makes no sense to you as a possible solution, then filter them out.
You cannot run the EZ Optimizer after you have manually created all the filters. If you do, it will delete your filters and create its own simple filters. You need to run the standard optimizer.
