F3B & F3F rules on airfiol shape shifting! Sceptics welcome!
Ok, I am just a dork when it comes to rules of competition, but... What if we changed the airfoil in flight? Servos that change the aspect ratio or camber or any other thing we want of the wing at the precise time we need speed or to manage effiency of the airfoil? It can be done. It was outlawed in F1 (Formula1 competition) but it can be done in a number of ways! Check out this vid and see for yourself. Call it Frightfull technology from the master herself! This is a 2LB bird!
