Choosing the right airfoil shape is an important step in drone design, as it significantly impacts the drone's performance and flight characteristics. In this video series, I will be teaching you practically everything you need to know about airfoils, how they work, and how to select the best airfoil for your fixed-wing aircraft design.

    Thanks, this is a well-presented video. Looking forward to whatever else you produce on the subject of low-speed aerodynamics.
  • @FPVREVIEWS
    The video touched on the subject but didn’t actually talk about it. That’s the forward shift in CP with increase of AOA. Dealing with the effects of camber on the pitch of the aircraft, maintaining stability without losing efficiency is a major design challenge and something for consideration when choosing the overall aircraft configuration. It’s actually possible to achieve aerodynamic instability with dynamic stability at the same time with no moving parts.

    Easily the most comprehensive video on the intenet. I've been searching for something like this for weeks, imagine my surprise seeing this video was only a day old. Subscribed!

    Very good video! I like it a lot. Can i make a suggestion to change colour of airfoil and graphs for brighter for better visibility of diffrences :-) Good luck with Your project!
  • @ginonguegang9232
    The correct lift equation has the aircraft wing area and not the wing chord
  • @Boogie3D
    2:25 You should specify it better. From your description you can have a relatively thin (5-6%) undercambered airfoil and the max difference betwwen upper and lower surface would make it something like 7-8%.
