I built this Goldberg 1/2A Blazer in the summer of 1974 and flew it many times as a glow-powered free flight. After over 40 years of storage, the old girl was getting a bit tattered.
I stripped off the old silkspan tissue with acetone to reveal the badly warped structure. Reinforced things with gussets and a bit of carbon fiber at the center section joint, covered the fuselage with silk and shot on a coat of automotive primer as filler. Recovered the wings with heavy grade tissue and brushed on a coat of nitrate dope. Increased the fin area by 50% on the advice of others here on the forum (thanks Franny) and shot the fuselage and fin with Krylon flat white.
Motor is a Chinese brushless and battery is a 750 ma-hr 2-cell lipo.
