  • Weight: ca. 1kg
  • Wing Span: 140cm
  • Wing Area: 46cm^2
  • Thickness in the middle: 46mm

The setups I found use an engine with ca. 75g, 1000 rpm/V to 1250 rpm/V (revs per minute per volt), a 3 cell Lithium Polymer battery with 4000mAh (due to the geometry of the plane we use 2*2000mAh in parallel) and a 10*6“ folding prop with a 40mm to 42mm middle part.
