along finished two Piper Tomahawks several months ago anxious get flight photos book finally got pictures needed wound up taking almost four months Like have flying weekends first thing got way weather seemed no matter nice during week always rained weekends weekend weather nice change could bet Out town business beginning think would have quit job camp Out field order catch good day week somebody goofed rained Wednesday Thursday said myself got out field bright early beautiful Saturday morning Jim Messer version Thawk got couple fellow club members run through Safety Checklist made range check radio got ready start engine Although engine Magnum II run plane yet run test stand Big Bangers series really wasnt expecting problem after half hour cranking pop reached conclusion werent getting spark ignition module packed up went home confirmed no matter fast spun flywheel no spark plug elec tronic ignition module apparently gone bad kind thing doesnt happen often no doubt Contempo would replace could see two three good weekends going down drain waited Monday however found Out firsthand what Contempos deal Homelite means modelers using Magnum II engine based Homelite chainsaw unit Home lites service centers over country will warranty other maintenance pulled 40 Model Aviation HOW check radio glitches hereThese some disassembled sections 6-yearoldtransmitterantenna Notethedirty oily residue buildupon underthesliding contacts antenna depends good Contact order transmit properly Above left Bob blasts oft newly-built Jim Messer Piper Tomahawk first flight Right flyby something just didnt look quite right second flight Below left Bob greases inbut pesky nose wheel now gone Right inevitable result Good photography Bob Beckman Jr four flight shots caught clods turf still flying ship grinds stop dug out air scoop cowl didnt break prop See photo next page see Bob kept recurring module off engine leaving engine plane headed Homelite site Alexandria VA explained problem within 10 minutes way home new module place lots fat spark plug problem out way time others start showing up Between some health problems trying get few major Giant Scale Fly-Ins weekends started slipping away fast About time pull engine out plane test runs will reported next installment Big Bangers Big Birds finally got act together engine andyou guessed itthe radio started giving trouble First noticed some glitches transmitter close plane starting engine can sometimes due overload ing receiver cleared up soon moved few feet away made range check antenna collapsed goed s gotten last check several weeks ago time wasnt good used getting same equipment other aircraft extended antenna found increased range six feet No way going fly under conditions another set frequency modules changed over tried again Things looked good put aircraft back together made range check relinquished pin other fliers fueled bird relaxed bit nice warm sunshine About half hour later got pin again prepared start engine immediately painfully obvious radio absolutely dead few quick checks determined batteries right transmitter putting out receiver Inoperative packed up went home again beginning very embarrassing since people field starting say things like Oh brought out again During next week found replaced heat-sensitive transistor second receiver checked tuning operation both sets frequency modules next weekend went confidently field have same sequence events take place change receiver didnt quit completely although point seemed continued operate unacceptably low lange tried re-orienting receiver antenna some slight changes operation enough make things usable beginning think might getting zapped rudder elevator drive cables and/or long servo leads aileron servos split-battery system shielded servo leads have never kind trouble before always first time last desperate effort pulled receiver cut another plane tried Same problem insufficent range same receiver has giving solid performance Sig Kavalier past three years did die put Giant Scale aircraft Welljust heck lets see what transmitter use Kavalier does controls arent set up same example rudder worked elevator can least see radio working ofcourse now perfectly adequate range Control solid block away antenna hown time doing range checking home wasnt about go Out field again until worked finally got through thick skull problem trans rnitternot receiver Thursday Drill hole nose wheel assembly shaft use 1/16in tension pin instead usual shaft-collarand-set-screw arrange ment retain nose wheel
