In 1917 Schiefer & Sons Aeroplane Co built the RS, designed by N B Robbins. A Pursuit trainer based somewhat on French V-strutted Nieuport design, it first flew on 9 December 1917.
The sole example was bought for a reported $11,000 and tested by the Army, but rejected as not being as good as Orenco or Thomas-Morse.
