Greetings from a newbie model boat builder: As part of the fine tuning of school curriculum process, many schools have a Science, Technology, Engineering, and Math (STEM) committee. Their function is to advise school boards, principals, and other stakeholders on how to upgrade science, math, vocational, and other classes to meet the evolving skill requirements that confront today's students. Some schools have topics like robotic classes and model rocket/Space Technology classes as part of a curriculum for middle and high schools. My particular district has a Combat Robotic class in 2 of the schools. However, the robots can get to be very expensive (especially as the number of kilograms climbs). I was going to proposed a modified RC Combat ship as a less expensive alturnative to the list of robotic clubs. After some research, I quickly abandoned the stock kits from BC and Strike. One kit exceeds the cost of some larger combat and non-combat robots. The kit prices were even reaching the point where I could send a student to the annual Aerospace Industries Association (AIA) competition near Washington DC (about a $1,000). That type of budget would not work for a school. I myself have visited the BC production plant in Sanford, FLA. It is amazing how they build BB cannons ! I bought one cannon and plan to buy a second. To house them, I am building 2 ships. One is based on the British armored cruiser Black Prince/Terror and the other will have a superstructure that mimics the Flower Corvette class. The fixed costs are being kept low. The cannon kit with regulator and gas bottle is about $150. The Radio set is a 2 channel from Tower Hobbies for $50.00. This gives me port, starboard, forward, and fire the gun. Items like the prop shaft and other parts are small cost items ($20 or less). The hulls were inspired by another model boater who used tongue depresser/craft sticks to build a few fishing tug models. At about $3.50 for a case of 300, I can build 2-3 hulls 60 centimeters long by 12 centimeters beam and about 10 centimeters in height. Add another $10 can get you assorted balsa or poplar a bag and wood glue. Dollar tree tissue paper and aircraft dope takes care of waterproofing and $.50 acrylic covered with polyurathane takes care of the finish. Some of the items are hard to price. I use chipsticks for masts qnd scrap PVC for a barbette. When I am done, I have a ship that somewhat resembles the Flower class Corvette with some variations allowed for superstructure (from US Civil War ironclad to dreadnought era) for about $250. This is about 1/3 the cost of a Strike Models South Carolina/Michigan model. This is less costly than the AIA TARC student event in Washington and the price would be about the cost of robots. It is within reason for a school budget with about 25 advance shop students. Best of all, the advanced shop student can take the boat home with them at year's end. As for rules and clubs, sadly, BC made an accurate observation. They noted that what I am trying is outside the norms of RC Warship combat and they could be only of limited assistance due to the specialization of their kits. I responded by noting that I am marrying different technologies in a new way. As for lettered clubs like IRCC or whatever, I was told they would not be of much help. They adhere to "the rules". Reading past posts about "ship crews teams, old 1:150 scale boats, silkspan thicknesses, rudder sizes, approvals for certain warship designs, etc., "adherance" may be a bit mild of a word. To me, your "rules" are a cost overrun neither I and my students or school can afford. I like fine scale craftsmanship. It is nice to see it. I admire it. It just that, from a education standpoint, they are unnecessary and impractical. As an educator, I hope to get some vocational use out of this hobby. May the hobby survive the economic winds that may yet come. A.
