Regin instructed Sigurd to dig a pit in which he could lie in wait under the trail Fáfnir used to get to a stream and there plunge his sword, Gram, into Fafnir's heart as he crawls over the pit to the water. Regin then ran away in fear, leaving Sigurd to the task. As Sigurd dug, Odin appeared in the form of an old man with a long beard, advising the warrior to dig more trenches for the blood of Fafnir to run into, presumably so that Sigurd does not drown in the
RRG Fafnir covered ahead of the spar, with fabric covering aft. Laterally stabilising dihedral was not common on gliders in 1929 but Lippisch applied it to about 40% of the inner span on the Fafnir, producing a gull wing. Many later gliders followed this form, though it is harder to build and has no solid aerodynamic justification. The trailing edges of the outer part of the wing carried broad and constant chord ailerons. The Fafnir's fuselage was oval in cross section, carefully streamlined with a ply skin and becoming slender behind the wing. The cockpit was just ahead of the wing and
