The Competition company was set in 1966 in Santa Ana, California. It was a sister company of the Pactra-Stormer Corporation. Competition was the lower-price version of the Pactra kits and ready to race models. All the kits had a chassis similar to that of the original Pactra "top & bottom" brass tubing chassis, but without a drop arm as on the Pactra models. Competition used the later Mabuchi FT16D motor with brush heat sinks, while Pactra used the more expensive Igarashi/Strombecker "Hemi" motor. Competition had their own proprietary wheels and tires, different from the Pactra parts. Both used the same guide flag and crown gears, as well as other features such as body-mounting pin tubing. Both shared most bodies, but some Competition kits used bodies that were not used on the Pactra models. The chassis were constructed using an interesting and novel soldering process: as the chassis were assembled from pre-cut, preformed brass tubing and stampings into jigs, they were painted in their joints with a liquid paste containing soldering compound. They were then placed on a rotating belt that brought them under an oven that melted the solder, then were left to cool. The chassis were then rinsed in an acidic product, washed in clear water, dried and packed. Competition kits are rarer than their ready to race models, and also rarer than their Pactra deluxe versions. The reason is probably that by 1967 when most were issued, racers wanted ready to race cars and simply were no longer interested in building, more in playing, so fewer were made. The LASCM is interested in purchasing any Competition kit not already in the collection.
