My first time cutting true airfoils with a home made hot wire cutter. Used a Variable DC Power supply with Nichrome 26 gauge wire. 24 Volts and just over 2 amps was enough power to cut a 48" span of Dow Corning Foamular 2 inches thick.
These wings are 48 inches wide for a total wingspan of 96 inches. The chord is 15 inches.
Worked like a charm.....
