We are using the DJI FlameWheel F550 frame for our first production model of the DroneKone Professional because of it's commercial value. It is a great platform by DJI. We understand that the DroneKone will add weight and mass to a Multi-Rotor copter.


To handle the weight we use a basic induced power formula.  The very basic calculation is a ratio between motor power and rotor size with respect to the weight of a six rotor copter.  The DJI F550 sports (6) EA 9.5" blades.  There is no wanting for lifting and stable power. One of the most simple formulas is Required Thrust = (Weight x 2) / 4.


The DJI products operate with minimum RPM leaving a lot of headroom for manuvering, but generally use 30% of their capacity while hovering.  The slight weight of the DroneKone  will more than be compensated for by the thrust of higher RPM's.  It won't change the center of gravity and will not tax the motors.

There are too many engineers working on the Thrust vs. Weight Dynamics for quadcopters for us to site them all.  Below we have sited what we believe to be a excellent document discussing the formula's and designs.
