Check the listing for details. Berkeley SUPER ZILCH PLAN To Build a 52" Span Old Time UC Stunt Model Airplane. Condition: New. Listed at 18.95 USD. I AM NOT SELLING MY MODEL PLANE, only a new, full-size copy of my original kit PLAN of the Berkeley SUPER ZILCH to scratch-build one like mine. The SUPER ZILCH was the kitted version of Jim Saftig's INVERTING STUNT PLANE produced by Berkeley. It changed UC model stunt flying forever. The model has a 52" span, straight chord wing and no flaps. Flaps did not come along until Bob Palmer's GO-DEVIL design a few years later. The old ad is from a 1949 Air Trails. By the way, the airfoil on the original INVERTING STUNT PLANE was thicker than is this SUPER ZILCH or the later SUPER DUPER ZILCH. I built my SUPER ZILCH using Saftig's earliest thick airfoil in order to have a slower stunt pattern. I have an Ohlsson & Rice .60 engine on glow in my model I picture over my copy of this great PLAN. The PLAN shows a Super Cyclone .64 as well as an Ohlsson & Rice .60 ignition sideport engine in the nose. But a Fox .35 would be ideal today for this classic old timer. All necessary parts patterns are shown on this PLAN. I list the above mentioned SUPER DUPER ZILCH separately. Keep it in mind for a future build. I AM NOT SELLING MY MODEL PLANE, only a new, full-size copy of this really big old time kit PLAN. Normal 0 false false false EN-US X-NONE X-NONE
