\subsection{Survey of Existing Approaches} \label{ssec:existing}

Because few remote control (RC) setups allow for live telemetry, almost all flying is done "by eye," and RC instrumentation and data logging is a poorly developed field. RC gliders especially eschew any projecting elements which could increase drag. The few relevant RC systems the author has found are described in this section, but most considered designs are in practice found only on manned vehicles.

\noindent \textbf{Vane Type}

Commercial aircraft typically have leading-edge high-lift devices, making the wing leading edge unsuitable for reliable angle of attack (AOA) sensors. The circulation about the wing in high lift configurations necessitates a probe placed far (one or more chord lengths) from the wing to avoid induced flow or complex calibration and correction software. It's common practice to place AOA and angle of sideslip (AOS) vanes on the fuselage, near the nose to avoid measuring wing circulation. Most probes are internally heated due to the need to fly through icing conditions without loss of data.

Nose-mounted air data probes are commonly seen on experimental aircraft during testing. They combine pitot-static systems with AOA/AOS probes, and frequently temperature, humidity, and other sensors into one probe that flies in front of the aircraft, far from interfering wings and the like.

Vane type probes are one of the few types seen in use by RC hobbyists. Tom Harper designed a balsa vane and potentiometer sensor for logging AOA in flight \cite{harper:vane}. Helmut Lelke designed a hall-effect AOA probe for use on his

    Vietnamese Culture Thesis Statement: The Vietnamese culture, a rich heritage on many different levels. Through exploring its religion, population, language, education, government, art and economics, an appreciation can be developed for the important contributions Vietnamese people make in American society. The early inhabitants of the area were Negritos. Some 4,000 years ago Austronesian (Indonesian) migrants from the north were moving into the area that is now North Vietnam. Later, Austro-Asiatic (Mon-Klimer and Maylayo-Polynesian) peoples arrived. Then, about 2500 years ago Viet (Yueh) and Tai peoples moved down from southern China. Out of this mixture of genes, languages, and cultures arose Van Lang, considered to have been the first Vietnamese Kingdom. In mid-third century B.C Van Lang was over run by and incorporated into another state to the north, forming the kingdom of Au Lac. Then Au Lac was incorporated into an even larger and more powerful state: Nam Viet. (Levison 284) Historically speaking, Vietnam (officially the Socialist Republic of Vietnam as of 1992) has struggled for independence for at least two thousand years, primarily from China. There have been brief periods when the country has itself p…

    In theory, the acceleration experienced by the glider can be calculated with the equation a=gsinƟ. Using this equation, the theoretical acceleration of the glider is equal to 126.291 m/s. We can obtain the actual acceleration by graphically analyzing the data. The equation relating the variables v and T is v2 = v1 + aT. This equation is simply a line with the equation y = mx + b. Thus, with velocity on the y-axis and time between the two photogates on the x-axis, acceleration is equal to the slope of the line. According to the slope of the best fit line, the acceleration of the glider is equal to 109.62 mm/s, with an error of 4.4076 mm/s. By taking the average to the maximum and minimum slopes within the error bars, the acceleration of the glider is calculated to be 115 mm/s.…
