neatest little maintenance trainer Ive seen years Its disguised under name 2-channel receiver sells currently $2195 What get money 2channel RC receiver kit easily convertible 4 channels simple straight-for ward design good construction manual just difficult enough solder give good training solder small parts tight places Now never fly thing will miles ahead understanding care factory-built equipment after have built little receiver particularly stick until have corrected mistakes made work cant think anything else will teach much price son Tim chief kit builder evaluating anything considered column normal interested junior-high school student possibly little brighter normal can its reason able suppose readers can Tim succeeded Now before rush off phone order Id like make sug gestion have plans fly receiver order 4-channel conversion PN 000436 additional $295 reasons follows 1 If ever expect piggy-back ICs required time before installing IC #1 cant imagine anyone adding IC #2 after kit completed theres no room tip soldering iron 2 The servo pulses transmit ter may put elevator aileron same stick cant select least four pulses Let illustrate what mean com ment 2 Saturday family showed up field nicely-built model Cox/Sanwa 2-channel radio As absolute beginners wanted someone fly Unfortunately no club flies Mode elevator left stick just enough experience Shoestring know didnt want responsibility either What As turned out system same frequency sons Cox/Sanwa 6-chan nel suggested might well ] give try As turned out Tims Mode 2 transmitter operated system throttle stick worked rudder aileron worked elevator No good Sorry folks couldnt get engine run went home find out Disappointment option left us point would have transfer Tims receiver engine troubles made unnec -j essary Now reason stopped first two pulses Tims coa trols stream did come aile ron/elevator control stick might have found controls re versed would have meant exchang ing plugs servo receptacles receiver Its also possible 12 Model Aviation servo direction would have reversed making necessary move pushrod opposite side servo arm Last month discussed control pulses may remember said transmitter encoder interrogates control-stick potentiometers sequentially order create On/Off commands transmitter oscillator What se quence does use Thats up person wires transmitter could done random manner system would still work normally change would notice would would necessary plug servos different receptacles receiver might otherwise expect find Fig 1 shows some pulse se quences measured transmitters shop names applied pulse due conventional way assigning functions control sticks After servo just servo until connected something using systems car might decide name Accelerate Brake Shift Clutch Steering Lights point Im trying make airplane RC systems based 4-channel setup can expect find aileron elevator somewhere among Additional func tions will assigned pulses 5 through 8 Therefore building 4-channel receiver right start assures success Getting back Royal receiver kit may know anything about electronics except end solder ing iron gets hot can read Eng lish follow instructions can build successfully trouble might have understanding markings capacitors Therefore will now enter brief discussion subject Electrical capacitance measured units called Farads after famous Brit ish scientist Michael Faraday 179 1-1867 credited discovery electro magnetic induction what makes hobby possible owe lot Mr Faraday may notice died 110 years ago young hobby Anyway Farad such large unit capacitance railroad locomo tives get much use out Electronic cir cuits use tiny bits capacitance called micro-Farads millionths Farad Capacitors micro-Farad range marked number followed K mF p F may marked col ored dots similar colored bands resistors Since Royal doesnt use type colored dots well ignore moment 33 micro-Farad capacitor may marked 33K 33mF 33pF High-frequency radio needs smaller bits capacity defined much smaller unit called pico-Farad micro-micro-Farad millionth millionth Farad may marked follows iSM l5mmF l5ppF l5pF 15 micro-micro-Farads just line everything up metric system defined unit between nano-Farad thousandth millionth Farad new capaci tor manufacturers simply mark Nso l000-pF capacitor likely marked simply lN think very confusing right find very comforting have capacitance tester nearby working capacitors construction manual does pretty good job identifying correct capacitor job pre-drilled holes printed-circuit board reject mistakes try make Fig 2 summar izes markings have discussed complete list possibilities run hundreds enough get through jobs can think kit such good training device First building will gain personal
