RADIO CONTROL AEROBATICS NY OF letters Ive getting deal two topicsThe first involves what kind odel beginning Pattern flier needs e results reader survey ect published last month wont ing about fhe second topic concerns kind o beginning Pattern flier needs cal letter Jim Staggs uquerque New Mexico have sport RC pilot ten rs want start flying Pattern i Nats-level competition am building Curare integration radio system must considered hype out concerning u system features feel perplexed h features useful legal tern flier specifically would micle readers featares genuine asset Pattern ipetitor feel fall other tgories Also features used competition ye preaching about subject s recently theme Ive tried across us really radio using Let explain sing analogy Theres hardly anyone would claim need Lamborghini drive work Yet fliers feel must have i1atest high-technology radio equipment Sportsman Advanced Masters class think ego id self-image have lot jets split out radio design features aimne worth relative Pattern ~sses fliers ability questions $uwer What needed perform flianeuvers Based pilots aility can take advantage t~io systems features radio system features Ill discuss channels AMIFMIPCM servo reversing dual rates variable trace ratio exponential adjustable travel volume control mixing servos model has retractable landing gear anybody really needs five-channel radio So top-of-the-line radios have ten channels Probably because its five six seven eight nine Most ten-channel radio owners never use channels couldnt figure out use wanted Lets get personal channels does radio have use Mr Van Putte answers eight five have eight-channel radio simple answer good buy might want install flaps aileron differential inflight mixture control next model have done things past models same time Obviously key answering numberof-channels question detennining what likely want during lifetime radio pilots ability really factor decision top-level pilots could whip up us four-channel no retracts systems AMIFMIPCM choice mixed other factors like number channels other features basic decision should based what works area home field could fly anything dont have interference outside some fields fly contests however outside interference Since get greater rejection outside interference go AM FM PCM use PCM radio Assess environment before making choice Servo reversing mandatory Pattern class level pilot ability certainly makes things lot easier installing radio gear Back servo reversing available go inside servos switch wires motor feedback potentiometer easy pleasant nor 100% successful Since almost radios have servo reversing its something usually dont have wony about Thank goodness Dual rates mandatory beginner classes Novice Sportsman use dual rates want increase reduce control authority particular function two common ones elevator aileron Most fliers flip high-rate elevator spins snaps Similarly low- rate aileron often used slow rolls None maneuvers Novice Sportsman maneuver schedules neither dual-rate elevator nor aileron necessary events fact after using dual-rate aileron slow rolls ten years discovered didnt need obviously begs explanation Ill give later First description variable trace ratio exponential needed During normal radio operation servo will move same amount incremental movement transmitter stick variable trace ratio selected radio will appear operate same way until certain point transmitter sticks movement point servos movement will still proportional incremental movement transmitter stick amount movement servo will before Its easy visualize think going up ramp changes angle about twothirds way up can change slope first ramp until effect causes system feel soft about neutral takes lot transmitter stick control input disturb models flight path before However certain point June 1994 65 glyan Hebert Louisiana readies original design Storm 4-S ls has waiting list two-stroke version Bob Pannell shows off decorating scheme bottom Nemesis has competed since teenager control authority required increased control pressure causes progressively model response total amount control authority remains same before exponential selected servo will progressively respond more incremental movement transmitter stick Again visualize going up ramp time ramp continuously getting steeper As variable trace ratio total amount control authority remains same before Since slope servos response very shallow about neutral control feel similar variable trace ratio What advantage using variable trace ratio exponential flying Pattern First either used aileron elevator model will respond smoothly about neutralthe model feels groovy better judges will appreciate models smoothness since major factor judging criteria smoothness gracefulness Second same amount control authority still have push stick little farther really good fliers can control stick inputs better rest us can benefit using variable trace ratio exponential believe exponential better variable trace ratio because control authority steadily increases transn$t stick moved knee control response curve variable trace atio sometimes causes problems example performing outsi& loops occasionally dont have quite enciii4li down elevator fed model approachs bottom loop feed bit~ down elevator sometimes push stick just past knee control response curve get too much down elevator causes kink loopsomething judges never missand am appropriately 66 Model Aviation r Cespedes installs Aeroplan wheel Don Weitz model Californian Steve Helms
