38、 buy Almost-Ready-to-Fly(ARTF)planes.“Instead of two hundred hours building a plane,you can do it in about twenty,”Motta says.“In that time,youll have a plane that is respectable and good looking.”The ARTF planes come in fewer pieces,which saves on assembly time,but they can be heavier and harder to

39、 repair.While planes are challenging to fly,helicopters with a single rotor on the top of the fuselage can be even more complicated to handle.More than half of the first-time fliers crash their helicopters in the first minute if they arent careful and dont educate themselves before flying.Some types

40、,such as mini helicopters,make learning to fly easier,especially indoors,but they still require practice.Although these RC copters are small,they can teach pilots many of the skills necessary to fly bigger helicopters.A boy flies his RC mini helicopter through an obstacle course as part of a competi

41、tion in China in 2013.Fun by Remote Control Level Z216Quadrocopters,also known as quadcopters,have four spinning blades,usually at the corners of the vehicle,and can fly in all directions.Autogyros look like a cross between a plane and a helicopter.A propeller at the front or back moves the aircraft

42、 forward,which causes the unpowered blades on top to spin and keep the autogyro airborne.Its a phenomenon called autorotation.One advantage of all the copters is that they dont need a runway to take off or land.Since 2013,International Search and Rescue has used quadrocopters with cameras in its tra

44、 jet plane,but they are every bit as fun.The Birth of Radio ControlWe can thank Nikola Tesla for conceiving the idea for the first radio-controlled machine.He was born during a lightning storm on July 10,1856,in what is now Smiljan(SMEEL-yawn),Croatia.Tesla became an inventor whose experiments in el

45、ectricity would inspire radios,radar,and robots.As a young man,Tesla had the idea to use radio wavesinvisible airborne ripples of electromagnetic radiationto control a boat.His“Tesla coil”laid the foundation for wireless technologies,including radio-controlled machinery.Teslas experiments eventually

46、 led the scientist to New York City in 1898 for Madison Square Gardens first Electrical Exhibition.It was there that Tesla first demonstrated a radio-controlled boat that shocked and delighted attendees years before most people had even heard of radio technology.Fun by Remote Control Level Z26Using

47、a homemade transmitter,Tesla sent a series of radio signals to the 4-foot(1.2 m)craft as it floated in a large tank of water built for the demonstration.The small boat moved gracefully around the tank in response to Teslas silent commands.It even answered math questions from members of the audience

48、by blinking its lights.The crowd was stunned.Some accused Tesla of using his mind to control the boat.Others said it must be magic or that perhaps a trained monkey was hidden inside.In actuality,the boat worked because of a series of levers,gears,springs,and motors controlled by a coherer,a radio-ac

49、tivated switch.The demonstration was front-page news.Tesla called his invention the teleautomaton.Tesla did not invent the boat as a toy.He had grander plans.Tesla hoped the U.S.Navy would buy his radio-controlled device to guide torpedoes through the water,but that never happened.Teslas demonstrati
