I am looking for a general understanding of how frame sizes are defined or described for hexacopters.
When I see a hexacopter frame defined as 550 or 600 or other larger sizes, are there typical or common prop sizes that are used for those frames?
Is that measurment from center to center of opposed motors/props?
Is there a tutorial out there that addresses these questions of props sizes for a given frame size?
Is there an accepted minimum size that is considered a "heavy lift"? What would it be called if it were smaller/lighter than a heavy lift but nit a mini? Does anyone build a "medium lift"?
