The Extra 300 SHP is designed for all out 3D flight. The Extra 300 was developed around a wing that has a thinner airfoil with very accurate, sharp LE that makes for a great stall breakaway and very precise flying airplane. To better understand this concept I would like to suggest you take a look at
this thread. The posts in this thread clearly illustrate the benefits to 3D flight that a thinner airfoil wing can have on a 3D airplane. What this all comes down to is a 3D plane that will be rock solid in high alpha flight modes, can be flown at slower speed with out the fear of a tip stall and a plane that someone can build confidence in very quickly.
One of the things I notice with new planes when they get announced is there is never any video to see how the plane actually flys. Not to be the case however with the new 3D Hobby Shop Extra 300 SHP. Here is a little "teaser" video for you.
