The Arcore was designed at the Centro Volo a Vela (CVV), or Experimental Soaring Centre, of the Royal Polytechnic of Milan by Gildo Preti.
Both were wood and fabric single seat competition gliders, cantilever monoplanes with mid-mounted gull wings.
The Arcore had a shorter landing ski than its predecessor, ending at a fixed, partly recessed monowheel assisted by a small tail bumper.
As before, its horizontal tail was raised above the fuselage on a shallow step but the elevator area was reduced by taper and it carried a small trim tab.
Only a few, possibly only one, were built; one source[2] says four but pre-war civilian registers[3] contain only the prototype, I-DICI, which is also the only Arcore in the official record.
