Until recently, most RC planes by small two-stroke engine, was powered by liquid fuel. Models powered by electric engines rather than the power system and battery have been rare because of excessive weight. However, electric RC planes, models are becoming commonplace, especially for beginner pilots.
Electrical advantages, low noise, low vibration, clean operating reliability, are easy to use. Disadvantage of early systems was low power according to weight. However, modern electric aircraft engines, advanced batteries with electric RC aircraft and the performance has increased by leaps and bounds.
Brushed motors are more common, the current transition is done using the sliding contact brushes. These brushes will run to get hot and timing. As brushless motor speed control switch electronically using a special happens. Engine control, and more for this second type are expensive. There is no maintenance and high performance advantages.
Here used for aircraft engines to power three main types of battery packs are available. This Nickel Cadmium (NiCad) are available, Nickel Metal Hydride (NiMH) and Lithium Polymer (Lipo). Lipo battery for an application, the more light is more expensive than NiCad or NiMH.
Electric RC aircraft types, including power sailplanes, indoor flyers, scale models and models of air acrobatics and video fan (jet-type). RC model electric power can be almost any kind now. There is now a practical reality even electric helicopters. For this new start, something slow and steady is recommended for a trainer aircraft.
