RE: Short Course Electric Trucks mostly being offered in RTR Form Only!
I don't think there's a whole lot in a kit that precludes it from mass production. For example those little sample bottles of some new perfume or skin treatment lotion they give out free in the larger department stores? Those are mass-produced and then sent to key markets to be handed out en masse. What stops a kit from being mass-produced is the business itself, there just isn't enough demand for a kit. No business is going to mass-produce a kit that only sells best case two to three thousand nationwide.
