"thinking outside the box"
The material in this book is a compilation of computer generated images, hand generated sketches and engineering data, gleaned from hundreds of pages of documentation in the public domain, about the many research projects conducted in Germany through the course of the second world war. Most of the aircraft under development were constructed of non strategic materials, such as wood and composites. As the end approaches in 1945 the projects take on an ever increasing tone of desperation, which is reflected in the extremely non conventional nature of the aircraft designs. The engineers and scientists working on these research projects were to use a modern phrase "thinking outside of the box". The flight testing aspect of these radical designs were extremely dangerous to the flight crews, who incidentally were in a large part women. All of the experienced pilots were engaged in operational duties and could not be spared for test pilot duties. Many of the projects were destroyed in bombing raids by the quickly advancing Allied forces and their existence would have been obliterated from history had it not been for the teams of engineers and scientists who were tasked to gather information by interviewing the personnel who worked on these projects. The volunteers at Luft '46 are dedicated to the preservation of this aeronautical history

Our story begins where it left off in part 1.
Eric our hero was soon to turn fourteen. A few short months earlier he he was forced to quit school, take a job in order to help his family after his father who, died suddenly of the deadly Spanish flu. Since Eric thought that his name was more suited to that of a boy he asked of all around him, that he be referred to as Ike.
Ike and his friends developed in intense interest in the air race that was shaping up in their town. They had visited the centers and bases of the ``birdmen``, as the local population called new airplane visitors from away. Ike had been to Glendenning farm at Mount Pearl and met the members of the Sopwith Atlantic team, as well as their pilot Harry Hawker and his navigator Mac Grives. They had witnessed the arrival the massive Curtiss Flying Boats of the Americans at Trepassey; greeted the arrival Raynham and Morgan`s big Rolls Rice powered Martinsyde biplane and; the gigantic Handley-Page V/1500 four engine Berlin bomber of Admiral Kerr.
They were there trying their best to prevent the inevitable disaster with the giant American ``ace in the hole`` entry, the C 5 airship of Commander Richard Byrd at Pleasentville in Quidi Vidi. They waited patiently for news of the missing Sopwith which disappeared somewhere in the stormy North Atlantic with Harry Hawker and Mac Grieves on board.

50 years of RC Model Aircraft
by David Crocker, davideo4301
50 years of Memories Flying RC Models: This book traces the development of the sport of building and and flying radio control model airplanes from the early 1960's up to the present day (October 2012). From a time when one had to build the airplane from a kit or scratch build from available material, then assembly their own radio equipment, to a time of Ready to Fly professionally built scale models or Plug and Play setups. The book is comprised of photos, descriptions, embedded videos and hyper links.

RCV - Rotary Cylinder Valve Four Stroke Engine
.JPG)
.JPG)
.JPG)
Engine Overview:-
The RCV - rotary cylinder valve four stroke engine represents a major advance in model engine design.
Although its moving components (piston, crank, cylinder and rotary valve) are totally conventional,
they are arranged in a radically novel configuration to provide the aero modeller with several key benefits,
whilst having similar handling characteristics to other 4-stroke model engines:-
Design Features:-
The engine still uses RCV's unique rotary valve system - which has only one extra moving component to a 2-stroke and so is easy to maintain. Its ultra low profile, means the height of this engine is approximately 18mm less (compared to OS & Magnum) & the highest point is 14 mm further back which makes cowling much easier than with other engines.
Observations:-
Based on my limited my limited experience with this engine I have concluded that this engine is a candidate for an on-board ignition system to prevent low throttle engine flame outs and the inevitable dreaded dead stick landing that comes with it. A close look at the manufactures instructions reveals that he highly recommends using an OS type "F" glow plug with this engine: something that I intend to try before going through the expense of installing the on-board ignition system. I have a plan to try this engine in an old-timer Red Zephyr that I have mounted on floats. This plane is a joy to fly but with its present OS 40 2 stroke it could do better with the extra power of a bigger engine, like this RCV.

Main Components
How it Works | |
| At the top end of the rotating cylinder there is a single port leading to the combustion chamber. This is surrounded by a fixed timing ring with three radially arranged ports; inlet, ignition and exhaust. This simple valve arrangement serves the combustion chamber as the engine cycles through the conventional 4-cycles: induction, compression, power and exhaust. Ignition is achieved through a standard 4-cycle glow plug exposed once only during each complete cycle.The rotating cylinder is effectively combined with the rotary valve in a single component hence - RCV - Rotating Cylinder Valve. |  CD Cross Section View |
