I've been trying to design and build, my experimental Ultralight using electric propulsion system, My plane designed base on Slaler and Gensis ultralight , following is the primary calculation
Empty weight 120KG
cruise speed 120 Km/h
I'm trying to select a pair of Brush-Less Direct Current motors (BLDC) for my airplane, but I have no experience using BLDC's before, whereas there is a lot of BLDC ambiguous options (mostly in Aliexpress) which claim to be a different KW.
My design goal is to find the best possible options for propulsion to have longest possible flight time duration.
Following is the 3D image of my design (located in my GrabCAD account) any advice really appreciated
