		<description><![CDATA[I think it has always been a problem sellecting the perfect size propeller as specialy for new flyers. Selecting the correct propeller size for your rc airplane is very important, if you want to get the best performance from your engine whether it is a glow motor or electrick. Prop selection can be a bit of [...]]]></description>

		<description><![CDATA[High altitude has a noticeable effect on the performance of RC Planes. We use to stay in Durban and flew quite alot. We eventualy desided to move to Jahannesburg. We had a few flights, but could not understand why the performance of the plane was so bad, i meen, it was really shitty. It took for [...]]]></description>

		<description><![CDATA[A glow plug is similar to a spark plug, used to ignite the fuel in the very small engines typically used in model aircraft, model cars and similar applications. The ignition is accomplished by a platinum helical wire filament recessed into the plug&#8217;s tip. When an electric current runs through the plug, or when exposed [...]]]></description>

		<description><![CDATA[A glider is an aircraft with no motor which relies on compressed wind against a hill to carry it. The design of the gliders enables them to climb using rising air and then to glide for long distances before finding the next source of lift. This has created the sport of gliding, or soaring.

		<description><![CDATA[A radio controlled aircraft is a model aircraft that is controlled remotely, typically with a hand-held transmitter and a receiver within the craft. The receiver controls the corresponding servos that move the control surfaces based on the position of joysticks on the transmitter, which in turn move the plane. Flying RC aircraft as a hobby [...]]]></description>
