Need to convert millimeters to inches or vice-versa? An inches to millimeters conversion chart, complete with fractional equivalents, provided here free! Quickly translate between metric and imperial measurements. Fractions are NIST standard conversions.

Learn how proper ducting design, based on Bernoulli's principle, minimizes tip vortices and accelerates airflow, leading to significant increases in EDF thrust and overall efficiency. Essential knowledge for VTOL aircraft and future electric propulsion systems.

RC Airplanes that fly with gas, nitro engines are described by their size in CC (Cubic Centimeters) and Cubic Inches (CI). This article goes into more detail on what CC and CI mean including a conversion chart.

Aeronautics is one of the most importance scientific fields of our modern world. It brings together a vast array of skills and technology and contributes heavily to global GDP

Ever heard of Stringers in aircraft? In this article you will learn what they are and how they are used in Aircraft Design and how they are different from longerons.

Learn more about Wing Cube Loading includes free calculator.
Since Wing Area Loading (WAL) directly correlates to the size and weight of the airplane, it is not a good measure of an airplanes “flyabilty” or flying characteristics, this is where Wing Cube Loading comes in.

Cl v Alpha polar charts might seem intimidating as you choose an airfoil, but it’s actually fairly easy to understand. In this article, I’ll help you understand these charts and how you can use them in your airplane design.

A stabilator vs stabilizer, they look almost identical and they both control the pitch movement of an aircraft, however, how they go about doing so is different in one key way. Horizontal stabilizers, in many aircraft…

What’s the difference between dihedral and anhedral? Well, it is very important to an airplanes desired roll stability and maneuverability. Learn more about these two types of wing configurations.

A wing without washout is a wing that may cause a pilot to lose all roll control in stalled conditions creating a potentially dangerous situation.

Ever heard of a longeron? In this short article you will learn what they are and how they are used in Aircraft Design.
