The answer to the question: Where do you want to fly today?

  • Fully assembled (ARF) or ready to fly (RTF)
  • Significantly improved layup
  • Additionally 2x24k carbon rovings in the leading edge
  • All highly stressed areas additionally reinforced with CFRP
  • Diab Divinycell H35 PVC foam instead of balsa as a support material in the wing
  • Increased durability and service life
  • Finished wiring harness for fuselage and wings
  • Simple protective bags included

With its 2.500 mm wingspan, it is very handy and quickly built up by the few components. Whether in the thermal, in light conditions or in a brute slope wind with up to 6 bft - with the optional ballast everything is possible. The outstanding construction gives the model an exceptionally high speed range.

Its strengths, however, definitely play this model in the toughest conditions on a slope. The kinetic energy of a nosedive is perfectly used to immediately generate full height again.

Due to the uncritical flight behavior - even on landings - we offer you the absolute slope allrounder. No matter if you are beginner, advanced or professional pilot. Here all pilots really get their money's worth!
