Intergers and Floating Numbers

Intergers are whole numbers such as 1,2,3,4,5,.....120,....,etc. Floating numbers are not whole numbers such as 0.7, 2.5, 3.4, etc otherwise described as decimal numbers, also seen in an the earlier blog post:

Building Model Aircraft from Plans

The process of building model aircraft from plans can also be used even if you are building a helicopter from metal and composite materials, its just that a more complicated process will be needed to make the individual components, also seen in an the earlier blog post:

Lift Coefficient

In both cases of fixed and rotary wing aircraft the lift coefficient equation can be used to calculate the size of wings to produce the required lift. However, in the case of a rotary wing the equations are a bit more complex., also seen in an the earlier blog post:

Circles and Rotor RPM

An understanding of circle geometry is very important for rotorcraft, for example the rotor area needs to be determined using circle formula, also seen in an the earlier blog post:
