What would be let say some of appropriate airfoils for flying wing RC model ? Wingspan arround 1200mm and speed arround 700 km/h. Maybe MH64 or so ?

Thank you,

  • $\begingroup$ 700 km/h is very fast for rc aircraft, but not totally out of question. A couple of years ago, rc Jets exceeding 700 kmh/h (youtu.be/uCH64yciiq8) apeared $\endgroup$

I recommend one that has been used successfully before, and at up to 1000 km/h airspeed: The Göttingen 765 (source).

XFOIL data for the Gö 765

Used as a root airfoil on the DfS 94 and 194 (aka Me 163 A). The root airfoil on the Me 163 B was 0.4% thinner, but otherwise very similar.
