Explorer 4.0 BF V-Tail

"BIG FLAP" Explorer means variable camber wings have now taken a giant leap to higher performance!

Whether scratching for altitude in light lift conditions or speeding through sink to the next thermal, Explorer BF gives you a BIG advantage! And talk about slowing down to hit your perfect landing, this bird can really hit the brakes! And its V-tail reduces induced drag to an practical minimum!

Extensive experimenting and testing with different flap chords has resulted in this latest Explorer model. Super light, state-of-the-art construction methods combined with maximum airfoil camber flexibility and efficiency, plus Explorer's sleek, low drag airframe combine to make this Soaring USA exclusive sailplane impossible to beat!

Explorer BF 4000 V-tail shares the same, proven airfoil with the Xplorer 1 F3J model. With its new slimmer fuselage with removable nose, ballasting the plane is much easier.  

Wing is IDS friendly and wing servos are moved as close to the center of the wing as possible to improve handling of the plane at low altitudes when it matters the most to work out tight thermals. Weight savings are mostly achieved in construction of the wing and amount of material used. The model is suitable for F5J use only.

  • Carbon fuselage
  • Fully molded composite wing panels
  • Fully molded composite tail
  • Full accessory pack
