I know this will probably be an unpopular post.........but..........This entire thread is absolutely insane. I fondly remember the days of two day races with an appropriate number of ONLY NITRO boats that moved quickly and finished on time. Then someone decided we needed a "cheap and easy" way for "new people" to join the sport and suggested that a pull start, gasoline powered, air cooled, "spec class" would be the way to fill the ranks. Now I travel to far off races to sit for hours each weekend as the "offshore" bouys are put out and then picked up and gas class after gas class keeps us at the pond until all hours. The "cheap and easy to run" spec boats that were the original idea have given way to engines and boats that are more expensive and complex than most of the nitro boats. Years later, gas boats have not increased the number of people at the races..........only the number of classes. The same will be true of ANY new classes that are introduced. The simple truth is that running an R/C boat of any flavor is a complex undertaking and that in itself is the limiting factor of how many people are going to be seriously involved. If you would like to increase interest on a local level to have more people get together and "play with toy boats", that is fantastic and I wish you the best of luck, but, please let's not start any talk of adding classes to IMPBA or NAMBA RACES. Thanks for the consideration.
