The “Zilch” was designed by Jim Saftig and 1st published in the April 1951 Model Airplane News, and later in the Feb 1979 Model Aviation. Most popular version was that kitted by Berkley (originally the Super Zilch was in 1947). Today SIG still offers a Berkley mini-Zilch.
We scaled it to 48” for an old Fox 35 that needed a home. Our Zilch 48 came in at 31 ½ oz with Polyspan covering and dope finish.
