Useful Formulas used with Flying Model AircraftThe formulas presented on this page should be helpful to newcomers to the hobby. These are fairly basic and easy to calculate formulas that will give a good indication of what to expect from an aircraft before flying it for the first time. Some of these formulas depend on a rudimentary understanding of Trigonometry. I have attempted to explain just what you need to know as simply as possible. In this seriesPlease note that the above articles do not describe how to choose the correct parameters for your model aircraft design. The series teaches you how to do the math to convert angles to measurements, calculate areas, etc. If you want to learn how to determine the correct amount of side thrust, the correct wing dihedral or similar information then you will need to consult a trim chart. Before you can even begin to trim your model you must locate the correct Center of Gravity. If you fail to do this then any other trim adjustments you make will be wrong. Trimming a Radio Control Model AircraftThese links to external websites are provided to help you determine how to properly set up and trim your radio control models. Additional information sourcesAn excellent unit converter by Josh Madison. This is a freeware program that will convert just about any unit to any unit. Another way to convert units is to simply type your question into Google. I found this by accident by simply deciding to try it. Go to the Google homepage and type the number of units and the unit type into the search box. Then type "to" and the units you want to convert.
