coun tries around globe After observed workings ClAM meeting several days noted discussions meet ings usually strenuous detailed mentally demanding However regardless political beliefs delegates economic conditions back home model airplane building flying wasthe primary topic discussion noted AMA effec tive influential organization world aeromodeling scene Also feel us AMA members will eventually affected some extent de cisions made 1981 meeting Paris Some concerns noted follows 1 Offensive noise produced model engines major issue Almost countries represented have contributed effort make engines quieter Tuned pipes mufflers combina tions both being utilized research development needs done pro peller noise well engine intake noise Some government agencies neigh bors adjacent flying fields begin ning establish maximum noise levels model aircraft need definitive action offensive noise issue through out world delegates agree ever seems significant technical breakthrough effectively quiet engines has yet appear area needs great deal help modelers 2 seems trend toward use four-cycle engines course quieter high-rev two-cycle addition have realistic sound Several rules changes proposed permit use 20cc four-cycle engine instead 10cc two-cycle motor Radio Control Aerobatics up 30cc multi-engine Scale models recommended believe four-cycle engine trend will continue resulting reduction noise realism flight 3 Electric power developing very rapid ly around world present rate development feel breakthrough battery technology power cell configura tion will come soon impact types model flying Sailplanes Aerobatics Actually am qualified make predictions area Electroflight delegates enthusiastic rubbed off others specific rule changes additions will discussed detail

present meeting Mr Paulsen declined re-election chairmanship soon found myself nominee office agreed serve elected op position Although election after having served less year may seem prema ture assure approach con duct committees business will recognize long association noise problems issue very complex legislation measurement enforcement firmly believe public irritation caused models primary problem will try influence legislation reduce problem means will support introduce legislation attacks prob lem area rather push uniform soundlevel legislation approach also requires cooperation between Noise Subcommittee subcommittees repre senting various disciplines re quirements recognized same time pushing general reduction noise level world-wide basis will try have removed Sporting Code rules prohibit silencers will attempt set up award encourage development publication significant new approaches noise reduction forms will ac cepted fellows around world will try keep subcommittee membership representative spectrum noise prob lems world responsive problems program may sound easy achieve assure requires Noise Subcommittee business conducted extremely short time schedules may circulate recommendations other subcommittees comment rework within deadlines also re quires cooperation other sub committees legislation may attractive members expect ever will finally face facts noise hobby produces must reduced world-wide basis can find ways reduce noise reducing per formance will try go way end noise must reduced up us individuals groups find ways can reduce intrusion others privacy position must wear two hats must advise US delegation wants needs own country under hat chairman coordinate wants needs others may coincide work other subcommittees will nearly always wear chairmans hat hope will recognize fact delegate may get advice seems conflict advice have given subcommittee members other nations because feel own countrys needs specific areas

recent ClAM revived memories Most controversial agenda items year Distance task winches First Distance task commonly referred Task B Three separate schools ideas produced proposals 1 drop event 2 eliminate 12-lap cap 3 fly event man-on-man first got support ly people dont appreciate what true measure Sailplanes performance elimination 12-lap cap strongest support form studies made Swiss Austrian soaring clubs Com piled statistics since 1977 World Cham pionships South Africa through 1981 event indicate cap should lifted Swiss Austrian defense cap removal emotional one study includes what results would have man-on-man flown same events studies included F3B contests 1977 through 1981 flown Europe three World Championships bottom line study flier hindered 12-lap cap trying make up poor flight opening up cap good flier can offset Thats what distribution curves indicate Man-on-man received little support Strongest objections came bad experiences European contests held mainly Germany negative points cluded poor frequency control problems reflights random draws werent quite random Only purewith empha sis purerandom selection could guar anteed would man-on-man considered some Result wasno change Task B Proposals limit winch power re strict launching techniques ran ban ning winches sour grapes restric tions would require organizers have electrical engineer two physicists half-dozen lawyers present during launch What prompted concern restric tions wa course line stretching some fliers releasing models another 30 meters behind winch missile-like launches using 24-volt winches remote launching practices wit nessed Sacramento What settled upon First elec trical power limited 12 volts Sec ond breaking strain line shall between 40 50kg tested ganizers Incidentally 40-50kg figure originally read 75kg Australian proposal felt too strong using one-millimeter monofiliment line has line strength 40-50kg Australia modified proposal As launch positions Tasks B release model shall forward winch Task C model may re leased along line right angles winch line extends towards safety line allows flier farthest safety line launching have same advantage flier closest safety line proposal could called sleeper Denmarks changed twolap Speed four laps also wanted landing included wasnt accepted Dan Pruss Working time changed five minutes Other changes pulley system 175-meter line has approved Regular hand tow still 150 meters Five rounds must flown order have throwaway round Six flown old rule case World Champion ships five rounds must flown sour graphes oh yes 75mm nose radius official Some new rules will make ganizers chores bearable include allow ing organizers indicate launch direc tion based wind direction before preparation time No second stopwatch will required timers during Duration task because new rule doesnt require point reduction after nine minutes flier loses landing points anyway itself will tend keep back competition sour grapes happy say Once jugulars released meetings ended fond memories recalled about Sacramentolike hospitality Neil Joan Nolte George Steiner opened shop radio prob lems Israeli team gave Swiss spare receivers after latter crashed two planes due interference during practice session Sam Crawford called Ace RC parts sent gave Swiss team just Israeli team needed back Lee Renaud taking Japanese

Rules Change Another Voice Thomas Vallee last issue INA V January Competif ion Newsletter arguments presented Erv Rodemsky radical change FAI rules concerning FAI model specifications dont like proposal publicity has already received good example rank file FAI fliers need stronger voice creating policy have right free speech country would among first defend Ervs right express promote ideas However corollary disagree Erv also have right heard am convinced majority American Indoor fliers would vote against Rodemsky proposal given chance Elements Rodemsky proposal Model weight 1 gram 035

following reasons 1 obsoletes current FAI models components current models well 2 rubber weight rule makes event much difficult also creates grave inherently unfair supply problem Con sider following problem areas a Given rubber weight rule slightest difference rubber quality will give extreme perhaps decisive ad vantage b The flier able pick choose large stock rubber would have highly unfair unsporting obvious advantage c To competitive will need buy unusually large amount rubber test exhaustively discard has suggested can solved having contest management supply rubber contestants However torque character istics vary different types rubber different batches same type rubber Indeed have seen rubber quality vary con siderably within given skein spool nominally good rubber would royal pain contest management Further no matter good job management does would have lot highly competi tive highly angry people convinced perhaps rightly have really shafted really want open can worms 3 event will much difficult serious competitors following reasons a Each motor must weigh exactly 5 gram 0175 ounce b If tie motor 00087 ounce light have sacrificed five percent possible power duration serious competition enough de cisive c Rubber motors will have bond ed instead tied Such things weight rubber lube will become important etc d For same reason model must weigh exactly gram As practical matter means building light adding ballast ensure model being exactly weight e The square Pennyplane-like format may also require building light allow adding ballast allow efficient trim f Since cannot adjust power compensate different air conditions cell ing heights rooms will have com pensate building lot extra model structure particularly propellers g You may have build twice models point may need build two completely different designs good air bad air h Processing will pain 4 proposal has certain severe side effects a Adoption proposal would turn off lot current FAI fliers no guarantee would replaced b It would disaster low-ceiling record attempt work Contrary Ervs suggestion proposed model has no special advantage flying small rooms c The gap between expert novice would greater now d It would have problems high-ceil ing flying well Consider flying under rule Lakehurst bad day Romanian salt feel potential benefits Ervs proposal minor compared problems created believe majority FAI fliers would vote against proposal given chance However preferences Ameri can Indoor fliers may have no bearing outcome place things perspective should remember present weight rule

event will much difficult serious competitors following reasons a Each motor must weigh exactly 5 gram 0175 ounce b If tie motor 00087 ounce light have sacrificed five percent possible power duration serious competition enough de cisive c Rubber motors will have bond ed instead tied Such things weight rubber lube will become important etc d For same reason model must weigh exactly gram As practical matter means building light adding ballast ensure model being exactly weight e The square Pennyplane-like format may also require building light allow adding ballast allow efficient trim f Since cannot adjust power compensate different air conditions cell ing heights rooms will have com pensate building lot extra model structure particularly propellers g You may have build twice models

unsporting obvious advantage c To competitive will need buy unusually large amount rubber test exhaustively discard has suggested can solved having contest management supply rubber contestants However torque character istics vary different types rubber different batches same type rubber Indeed have seen rubber quality vary con siderably within given skein spool nominally good rubber would royal pain contest management Further no matter good job management does would have lot highly competi tive highly angry people convinced perhaps rightly have really shafted really want open can worms 3 event will much difficult serious competitors following reasons a Each motor must weigh exactly 5 gram 0175 ounce b If tie motor 00087 ounce light have sacrificed five percent possible power duration serious competition enough de cisive c Rubber motors will have bond ed instead tied Such things weight rubber lube will become important etc d For same reason model must weigh exactly gram As practical matter means building light adding ballast ensure model being exactly weight e The square Pennyplane-like format may also require building light allow adding ballast allow efficient trim f Since cannot adjust power compensate different air conditions cell ing heights rooms will have com pensate building lot extra model structure particularly propellers g You may have build twice models point may need build two completely different designs good air bad air h Processing will pain 4 proposal has certain severe side effects a Adoption proposal would turn off lot current FAI fliers no guarantee would replaced b It would disaster low-ceiling record attempt work Contrary Ervs suggestion proposed model has no special advantage flying small rooms c The gap between expert novice would greater now d It would have problems high-ceil ing flying well Consider flying under rule Lakehurst bad day Romanian salt feel potential benefits Ervs proposal minor compared problems created believe

serious competition enough de cisive c Rubber motors will have bond ed instead tied Such things weight rubber lube will become important etc d For same reason model must weigh exactly gram As

serious competition enough de cisive c Rubber motors will have bond ed instead tied Such things weight rubber lube will become important etc d For same reason model must weigh exactly gram As

following reasons 1 obsoletes current FAI models components current models well 2 rubber weight rule makes event much difficult also creates grave inherently unfair supply problem Con sider following problem areas a Given rubber weight rule slightest difference rubber quality will give extreme perhaps decisive ad vantage b The flier able pick choose large stock rubber would have highly unfair unsporting obvious advantage c To competitive will need buy unusually large amount rubber test exhaustively discard has suggested can solved having contest management supply rubber contestants However torque character istics vary different types rubber different batches same type rubber Indeed have seen rubber quality vary con siderably within given skein spool nominally good rubber would royal pain contest management Further no matter good job management does would have lot highly competi tive highly angry people convinced perhaps rightly have really shafted really want open can worms 3 event will much difficult serious competitors following reasons a Each motor must weigh exactly 5 gram 0175 ounce b If tie motor 00087 ounce light have sacrificed five percent possible power duration serious competition enough de cisive c Rubber motors will have bond ed instead tied Such things weight rubber lube will become important etc d For same reason model must weigh exactly gram As practical matter means building light adding ballast ensure model being exactly weight e The square Pennyplane-like format may also require building light allow adding ballast allow efficient trim f Since cannot adjust power compensate different air conditions cell ing heights rooms will have com pensate building lot extra model structure particularly propellers g You may have build twice models point may need build two completely different designs good air bad air h Processing will pain 4 proposal has certain severe side effects a Adoption proposal would turn off lot current FAI fliers no guarantee would replaced b It would disaster low-ceiling record attempt work Contrary Ervs suggestion proposed model has no special advantage flying small rooms c The gap between expert novice would greater now d It would have problems high-ceil ing flying well Consider flying under rule Lakehurst bad day Romanian salt feel potential benefits Ervs proposal minor compared problems created believe
