RC Airplane Database - Wing Loading, Aspect Ratio, Motor, prop, battery combo

Image
  A major problem while designing an RC plane is finding relevant data like wing loading, thrust or power requirements. I have compiled several RC planes in this database to make the search a little easier. I have sorted the planes into categories like gliders, trainers, sport, scale, EDFs, and so on. For each model, I have provided the total weight, span and wing area. Most of the information is obtained from the manufacturer’s or retailer’s website. For those planes that I could not find wing area for, I manually estimated it using Onshape by importing the top view of the plane. These wing areas are indicated with an asterisk mark. With the total weight, span, and wing area, the wing loading and wing aspect ratio are determined. It is easy to see the pattern of wing loadings and aspect ratios for the different classes of models. I have also included the motor, battery and prop combo for each model, so that you can get a reference while choosing a powerplant for your design. M...

How to design an Airplane Wing - Aspect Ratio, Taper Ratio, Sweep, Twist, Incidence, Dihedral

Image
  In this post, we will look at all the important parameters used to decide on the wing geometry and layout while designing an aircraft. The parameters discussed are aspect ratio, taper ratio, sweep, twist, incidence, and dihedral, all of which are crucial for wing design. Let’s get started. You can also watch this video for more on wing design: Once the total weight of the airplane is estimated, we can calculate the wing area by simply dividing the total weight by the chosen wing loading value. The wing loading value may be selected based on the stall speed requirements or by looking at the wing loading values of similar designs and choosing an appropriate one. If you haven’t selected it yet, you can watch one of my previous videos on wing loading for more info.

First, it extends through the ...

Designing a Model Canard Airplane: A Beginner’s Step-by-Step Guide

Image
  Designing a Canard airplane offers a unique set of benefits and challenges. A Canard aircraft features a smaller wing, known as the Canard wing, positioned in front of the main wing. This configuration can enhance maneuverability and improve stall safety. The process of designing a Canard airplane can be simplified by understanding a few key principles and calculations. This guide will walk you through the essential steps to create a stable and effective Canard model airplane. You can also watch the video below: Understanding the Canard Design A Canard airplane is distinct because it includes a smaller front wing (the Canard) and a larger main wing at the rear. This setup can reduce the main wing’s loading, leading to improved aircraft maneuverability and enhanced safety during stalls. In designing such a model, it’s crucial to ensure stability in flight by properly sizing the Canard and determining the appropriate center of gravity (CG) location. Calculating Wing Areas Before di...
