Motor / Prop selection ...
My idea is lets say a 1.2m span ... maybe 4 x 1200 - 1500kv motors with 7x5 props with 3S Lipo. (Correct me if thoughts are I should change that ...)
Question : With 4 props spinning away .. contra rotation. My thoughts are to not only have contra rotation based on each wing side .. but also the pair each wing ... that is ....
not only one pair contra to the other pair per side .. but also the two making up the pair are contra.
ie left outer anticlockwise rotation, inner left clockwise. Inner right counterclockwise, outer right clockwise.
The motors paired as inners and outers ... so in event of one system failing - we still have a prop either side turning.
