Radio Controlled Boats (Page 1 of 2)
A radio controlled boat (or RC boat) is a boat controlled remotely with radio control equipment. Electric Sport boats are the most common type of boat amongst casual hobbyists. Hobby quality boat speed generally start at around 20MPH and go up from there, and can be just as fast or faster than their internal combustion counterparts, with the latest in Lithium Polymer and Brushless motor technology. Ready to run speed boats from Aqua Craft, Pro Boat and Offshore Electrics can reach speeds over 40 mph out of the box and with modifications can reach well into the 50-60 mph range. These types of boats are referred to as hobby grade and can be found only at hobby shops and retailers. Toy grade boats which are obtained through mass consumer retailers, are generally much slower and their maximum speeds are usually less than 15MPH. Scale boats are replicas of full size boats. They can be small enough to fit into your hand, or large, trailer transported models weighing hundreds of pounds. More often than not they are a miniaturized version of a prototype, built using plans and/or photos, although there are variants that utilize freelance designs. An offshoot of this style of marine RC’s is radio controlled submarines.
Power boats are typically Fast electric or internal combustion, (ignition engine or glow plug RC engine based) and some are steam powered (conventional type, and also flash steam). (At one time some boats used engines working on the compression ignition principle. These were not diesels in the true sense of the word but the modelling fraternity frequently referred to them as such. A few enthusiasts still operate such engines.) The power is commonly used to rotate a submerged propeller, aircraft propeller or jet which in turn provide the thrust to move the craft. Typically power boats have two controls, rudder, outboard motor or stern drive and throttle control. Powered scale boats will often have additional remote controlled functions to improve realism, e.g. sounding fog horns, rotating radar antennae etc. Some of the more sophisticated powered racing boats may also have additional remote controlled functions. These may include remote mixture control allowing the driver to optimise the fuel/air mixture during a race. Another function occasionally implemented for racing boats using a surface piercing propellor is remote control of depth or angle of thrust. There are three main types of power boat. RTR (ready to run), ARTR (almost ready to run), and kit versions are available. All thoroughbred racing boats are made from kits and the builders add their own gear and radio.
Radio controlled racing boats are designed for maximum speed and maneuverability. Various styles of racing include circuits of different shapes laid out on the water with buoys. The most common courses are the 1/6 mile oval that consists of 330′ straight sections followed by 70′ diameter turns. The International Model Power Boat Association (IMPBA) as well as the North American Model Boat Association (NAMBA) have specific rules and regulations to address the course, race rules, and formats. In addition to oval racing there are straight a way (SAW) racing. This is a contest to see how fast you can make the boat go in a straight line. Timed events are held where the boats need to go through a starting light and an ending light. The speed is calculated by the timed difference from start to stop vs the length between the lights. Again IMPBA and NAMBA rules apply.
Hosted PBX fulfilling SMBs communication demand
When looking for a phone system it wont take long to notice that there are an overwhelming amount of options. Smaller businesses are often looking for an affordable solution that will provide many of the features that larger companies use. Business phones have gone extremely high-tech which is why Hosted PBX systems were created. While most businesses are in need of the intelligence that PBX systems offer, they are often prohibitively expensive and most businesses do not have the hardware or know-how to implement these systemsbut they do have the need for the business intelligence that they offer.
Hosted PBX provided from the premises of the service provider, so the small business can now enjoy numerous benefits without installing all the hardware or software typically needed with a new phone system.
With Hosted PBX system, company will be provided with a special router or switch that attaches to the network and is then connected to the external world. The router or switch communicates directly with the hosting service that provides the Hosted PBX. A Hosted PBX system is an IP phone system. Most of the hardware is hosted by a service provider on a monthly or annual basis, so that all connection to or from your website or sites go via the service provider.
There are several reasons why businesses are switching to a hosted PBX solution:
To reduce hardware costs.
To eliminate maintenance costs
To free up IT resources.
Easier management, tracking and reporting through online consoles than non-virtual PBX systems.
Versatile services that adapt to your changing needswithout need for hardware upgrades.
One of the biggest selling points of hosted PBX systems is the wide variety of features and add-ons that they make available to businesses. Features that were once reserved only for extremely large companies are now available with most hosted PBX systems. Popular features include Find-Me-Follow-Me technology, Outlook integration, extension dialing, call forwarding, and music on hold. The Follow-Me feature allows calls to be easily forwarded to cell phones or other alternate locations. This allows for the possibility of a completely virtual office and reducing office overhead expenses. Also, many of these systems also have an auto-attendant which allows calls to be directed during business both and off-business hours.
Another reason businesses are moving to hosted PBX services is that the business has gone nationwide or even global. Small-to-medium sized businesses can have offices and customers around the globe and a hosted PBX system can offer cost saving features plus long distance numbers and plans. The cost of can be just fractions of the cost when using a hosted PBX system versus standard phone line systems.
