Extra 300S photo
A big, beautiful aerobat with "point and go" performance.

The full-size Extra 300S, arguably the most popular Extra seen in competition, has seen many R/C versions modeled after it - but none quite like this one. Great Planes' .60-size Extra 300S is lighter than other similar kits, allowing it to fly better on a 2-stroke .60-.75 engine. "Builder-friendly" construction will inspire confidence in your assembly skills, and when airborne this Extra exhibits precision maneuvers that are nothing short of remarkable!

  • Perfectly interlocking CAD-engineered parts produce a fuselage that can be built flat on the board
  • The wing features simple D-tube construction that maximizes wing strength
  • A large radio compartment offers room for optional twin elevator servos, which improves flying characteristics and radio setup
  • Heavy-duty aluminum landing gear, reinforced by dual ply rails, spreads landing stress at impact across a larger area, for greater strength during rough touchdowns

cowl photo
Among the high-quality Great Planes hardware included in this kit is a precision-formed, 2-piece ABS cowl that fits nicely around engines in the recommended range to complement the sport-scale realism.
sheeting photo
The Extra 300S .60's lock-and-tab construction creates a strong, straight airframe, and the turtle deck is balsa-sheeted to virtually eliminate time-consuming carving and sanding.
radio compartment photo
The radio compartment not only allows for twin elevator servos, it's also spacious enough to accommodate a smoke system, if desired.
