The hobby of flying model airplanes with remote radio control and electric power has become very popular with the advent of efficient motors, batteries and inexpensive radios. Ready to Fly (RTF) planes and helicopters can be so inexpensive that almost anyone can afford to buy one. But, of course, you get what you pay for and sometimes a very cheap price leads to a disappointing product.The magic dollar amount for a RTF electric airplane is around $50 with offerings below that being mostly toys.
