ABSTRACT
The majority of RC component (Battery, ESC, BLDC Motor and Propeller) manufacturers do not state accurate empirical performance measurements for these vital parts. Those that do sometimes state inaccurate and/or inflated values, presumably to drive sales and to fool the unsuspecting consumer. It is therefore vital for the user to seek corroboration of data online and/or conduct their own static thrust tests, before specifying and purchasing a complete system solution. A rare exception to this situation is the data provided by the US-based propeller manufacturer Advanced Precision Composites who provide computerised performance data on their full range of 493 propellers used in both fixed-wing and rotary-wing aircraft. The majority of this design guide is focused towards the optimum design of an all-electric multi-rotor configuration. In terms of payload capacity, most small multi-rotors are designed to carry a small payload of about 0.5–1 kg.
