The original Golden Bee was a Baby Bee that has a larger (8cc), stunt vented fuel tank and has been anodized gold. The larger tank allowed the planes to fly longer while the stunt vents allowed the airplanes to fly inverted without fuel running out or the engine cutting out. The first versions of the Golden Bee had a single bypass intake port and same size backplate venturi opening (0.0625") as the Babe Bee but later versions had a 0.082" venturi opening to 11/64" at the reed valve while the Babe Bee was 9/64". This was the secret to its slightly higher power output. The 1969 and later RC version with throttle sleeve had two bypass #1 cylinder making them slightly more powerful again to make up for power losses due to the exhaust throttle sleeve.
