An array of improvements have been made to give this model a definitive edge in performance over the groundbreaking original. Beginning with the latest in Carbon-Z construction, the entire airframe features strength enhancements that increase its durability and the ability to withstand aggressive 3D maneuvers better than ever. At the same time, engineering enhancements allowed the low wing loading and 2-to-1 power to weight ratio to be maintained. The proven E-flite 25-size outrunner motor now uses an improved ESC that features a more robust BEC so the complement of upgraded digital servos can consistently deliver peak precision. Even its propeller has been refined to deliver greater efficiency and smoother power.The CA hinged control surfaces feature serviceable hardware with ball-links installed. The landing gear has been made slightly taller so that you can takeoff more easily from grass and perform Harrier landings with less risk to the propeller. The two-piece wings feature a carbon fiber joiner tube and bolt into place with a single socket-head screw each.
