This application is a collection of calculators that are convenient for modelers and R/C aircraft modelers in particular. The calculators were designed to be flexible in input configurations and to take input and output unit specifications in a wide range of choices.

I use these calculators often in my modeling and I find them handy for making educated guesses at the least. More calculators and features are in development. I have many more needs and now that I have the basic application and framework in place, I am creating new features as I need them. More free updates are coming.

The calculators and features in this release are:

• Unit Converter
• Wing Area
• Wing Loading
• G-Force
• Pitch Speed
• Engine Size
• Tank Size
• Gas / Oil Mix
• Propeller Chart
• Drill Size Charts
• Battery Voltage
