Hi Alisio, is it purely for top speed? If yes, then you'll probably be flying at a constant angle of attack, which means you can select an airfoil that is very efficient at a very specific angle of attack. Check our video on this: airshaper.com/videos/drone-design-1-selecting-an-airfoil/video/kAXN3MlQxxc - hope it helps!
Ah, that can be done in many ways. The most obvious is to work away any extremities & cavities (antennas, landing gear, gaps between body panels). Once you're at a level where everything is super smooth, you may want to start looking at optimizing lift/drag ratios by playing with the airfoil profile (that's more advanced!)
Are you working on a product where aerodyanmics may be relevant? Share your thoughts below if you'd like to start a discussion!
Cool video! Great for people to understand the basic applications of aerodynamics!
Thanks a lot Thomas! It felt good for us too, to take a step back and try to see the bigger picture :)
Thanks a lot Thomas!!
Excellent work on the drone Wolter.. 30% is huge... well done!
Thanks a lot Graham! Yeah, that 30% made a big difference, they now fly 90 minutes on a single charge! :)
Great videos. I'm planing on doing a top speed RC propeller foam plane (or fixed wing drone). What layout would you advise for lowest drag ?

Another brilliant explanation, Wouter! 😎👍 Kudos!

Thanks a lot Parkflyer, the love is much appreciated!! Glad you like it :)
Hi @AirShaper How can you reduce the drag coefficient in a UAV?

@@AirShaper okay. I'll try it out
