Mass Estimation

In order to determine which motor and propeller combination is needed to power the aircraft, the mass of the aircraft must be estimated. To do this estimation, all the different components that are needed to build the aircraft are found and an average weight of each component is calculated. All the components for this helicopter will be purchased from Hobby King because they have a wide variety of components at very good prices. Table 1 shows the components, their high and low weights, their average weights, and the accumulated total weight.

Table 1 shows an estimated weight of about 809g which will now be used to acquire the appropriate motors and propellers.
