John Preston Safety Comes Pint Peppertree Ln Sliver SprIng MD 20906 column provided address items concern regarding safety aspects model aviation activIties Content column however opinion author does necessamily repmsent official position Academy Model Aeronautics inadvertently shutting oft RC transmitter switches Over-revving props can dangerous Unsafe Launching rockets RC models Loose Tx antennas cause crashes THE OTHER SIDE coin write some thing column results receiv ing letters opposed what have said must doing something wrong However result discussion transmit ter power switches being inadvertently turned off appeared April safety column let ters appear about equally divided wheth er blame stupidity such incidents pilot person designed transmit ter Since took position felt stu pidity part pilot caused such cidents following other side coin ex pressed extremely well letter Jefferson City MO modeler William Stodgell two-year-old might should purchase transmitter tray Besides 30-plus years RC have never used seen anyone else use neck strap So instead nit-picking faultfinding criti cism think Airtronics deserves highest praise Vanguard FM transmitter have given us radio will enable us fly safely high-interference areas oth ers will noteven new radios adver tised being ready 1991 Airtronics has also given us radio will operate up three hours per charge making virtually impossible run down batteries dur ing average afternoon flying session have honest presenting package no-frills no-bells-and-whistles radio have jacked up price just because works others will What could manu facturer promote safety contrast some manufacturers have contin ued cranking out selling radios cant re ject pager interference cant reject 31M interfer ence will able reject 23-channelsyndrome interference 1991 beyond have radio will reject some types interference stick bunch bells whistles average Sunday flier does need want charge enormous price give us radio might run over hour half per charge Sure Airtron ics has radios like too want least have given us choice long time no else did Several years ago bought super radios bought least-super available time would give dual-conversion receiver PCM made mistake run ning preflight test see just long would operate per charge first day out wiped out brand-new airplane because overflew transmitter battery Obviously hoop de-doo fail-safe did save dayor plane either After found out just long would go per charge always timed radio time stopwatch also checked battery pack ESV expanded-scale voltmeter RMcM meter between flights recently re placed original battery pack transmitter SR series 700 pack Expensive yes would fit tight battery compartment just like 500 increased safe flying time per charge little over three hours instead original limit just over two hours So now dont have worry about batteries either still have no-good bells whistles contend So instead nit-picking good manufactur ers product pieces use space Continued page 16 second time Ive written first regard in-flight stab failure suppose could classify letter complaint want stress enjoy column very much think should contin ued means However resent space devoted publishing someones criticism Airtronics Vanguard transmitter agree anyone turning transmitter off trying adjust trim has committed stupid mistake also feel just because several fliers have done does point finger stupidity manufac turer rather points fact can make stupid mistakes perfect person walk earth crucified anyone afraid making mistake simple fix remove plastic switch slide recesses actual switch enough impossible turn off accident Probably people have killed cause someone pressed gas pedal thought pressing brake pedal does anyone call auto manufacturers stupid try get move gas feed up onto steering column like old Model Ford someplace else cant happen call radio manufacturer stupid try get him redesign transmitter order oper ate RC airplaneor safely drive

John Preston Safety Comes Pint Peppertree Ln Sliver SprIng MD 20906 column provided address items concern regarding safety aspects model aviation activIties Content column however opinion author does necessamily repmsent official position Academy Model Aeronautics inadvertently shutting oft RC transmitter switches Over-revving props can dangerous Unsafe Launching rockets RC models Loose Tx antennas cause crashes THE OTHER SIDE coin write some thing column results receiv ing letters opposed what have said must doing something wrong However result discussion transmit ter power switches being inadvertently turned off appeared April safety column let ters appear about equally divided wheth er blame stupidity such incidents pilot person designed transmit ter Since took position felt stu pidity part pilot caused such cidents following other side coin ex pressed extremely well letter Jefferson City MO modeler William Stodgell two-year-old might should purchase transmitter tray Besides 30-plus years RC have never used seen anyone else use neck strap So instead nit-picking faultfinding criti cism think Airtronics deserves highest praise Vanguard FM transmitter have given us radio will enable us fly safely high-interference areas oth ers will noteven new radios adver tised being ready 1991 Airtronics has also given us radio will operate up three hours per charge making virtually impossible run down batteries dur ing average afternoon flying session have honest presenting package no-frills no-bells-and-whistles radio have jacked up price just because works others will What could manu facturer promote safety contrast some manufacturers have contin ued cranking out selling radios cant re ject pager interference cant reject 31M interfer ence will able reject 23-channelsyndrome interference 1991 beyond have radio will reject some types interference stick bunch bells whistles average Sunday flier does need want charge enormous price give us radio might run over hour half per charge Sure Airtron ics has radios like too want least have given us choice long time no else did Several years ago bought super radios bought least-super available time would give dual-conversion receiver PCM made mistake run ning preflight test see just long would operate per charge first day out wiped out brand-new airplane because overflew transmitter battery Obviously hoop de-doo fail-safe did save dayor plane either After found out just long would go per charge always timed radio time stopwatch also checked battery pack ESV expanded-scale voltmeter RMcM meter between flights recently re placed original battery pack transmitter SR series 700 pack Expensive yes would fit tight battery compartment just like 500 increased safe flying time per charge little over three hours instead original limit just over two hours So now dont have worry about batteries either still have no-good bells whistles contend So instead nit-picking good manufactur ers product pieces use space Continued page 16 second time Ive written first regard in-flight stab failure suppose could classify letter complaint want stress enjoy column very much think should contin ued means However resent space devoted publishing someones criticism Airtronics Vanguard transmitter agree anyone turning transmitter off trying adjust trim has committed stupid mistake also feel just because several fliers have done does point finger stupidity manufac turer rather points fact can make stupid mistakes perfect person walk earth crucified anyone afraid making mistake simple fix remove plastic switch slide recesses actual switch enough impossible turn off accident Probably people have killed cause someone pressed gas pedal thought pressing brake pedal does anyone call auto manufacturers stupid try get move gas feed up onto steering column like old Model Ford someplace else cant happen call radio manufacturer stupid try get him redesign transmitter order oper ate RC airplaneor safely drive

John Preston Safety Comes Pint Peppertree Ln Sliver SprIng MD 20906 column provided address items concern regarding safety aspects model aviation activIties Content column however opinion author does necessamily repmsent official position Academy Model Aeronautics inadvertently shutting oft RC transmitter switches Over-revving props can dangerous Unsafe Launching rockets RC models Loose Tx antennas cause crashes THE OTHER SIDE coin write some thing column results receiv ing letters opposed what have said must doing something wrong However result discussion transmit ter power switches being inadvertently turned off appeared April safety column let ters appear about equally divided wheth er blame stupidity such incidents pilot person designed transmit ter Since took position felt stu pidity part pilot caused such cidents following other side coin ex pressed extremely well letter Jefferson City MO modeler William Stodgell two-year-old might should purchase transmitter tray Besides 30-plus years RC have never used seen anyone else use neck strap So instead nit-picking faultfinding criti cism think Airtronics deserves highest praise Vanguard FM transmitter have given us radio will enable us fly safely high-interference areas oth ers will noteven new radios adver tised being ready 1991 Airtronics has also given us radio will operate up three hours per charge making virtually impossible run down batteries dur ing average afternoon flying session have honest presenting package no-frills no-bells-and-whistles radio have jacked up price just because works others will What could manu facturer promote safety contrast some manufacturers have contin ued cranking out selling radios cant re ject pager interference cant reject 31M interfer ence will able reject 23-channelsyndrome interference 1991 beyond have radio will reject some types interference stick bunch bells whistles average Sunday flier does need want charge enormous price give us radio might run over hour half per charge Sure Airtron ics has radios like too want least have given us choice long time no else did Several years ago bought super radios bought least-super available time would give dual-conversion receiver PCM made mistake run ning preflight test see just long would operate per charge first day out wiped out brand-new airplane because overflew transmitter battery Obviously hoop de-doo fail-safe did save dayor plane either After found out just long would go per charge always timed radio time stopwatch also checked battery pack ESV expanded-scale voltmeter RMcM meter between flights recently re placed original battery pack transmitter SR series 700 pack Expensive yes would fit tight battery compartment just like 500 increased safe flying time per charge little over three hours instead original limit just over two hours So now dont have worry about batteries either still have no-good bells whistles contend So instead nit-picking good manufactur ers product pieces use space Continued page 16 second time Ive written first regard in-flight stab failure suppose could classify letter complaint want stress enjoy column very much think should contin ued means However resent space devoted publishing someones criticism Airtronics Vanguard transmitter agree anyone turning transmitter off trying adjust trim has committed stupid mistake also feel just because several fliers have done does point finger stupidity manufac turer rather points fact can make stupid mistakes perfect person walk earth crucified anyone afraid making mistake simple fix remove plastic switch

being inadvertently turned off appeared April safety column let ters appear about equally divided wheth er blame stupidity such incidents pilot person designed transmit ter Since took position felt stu pidity part pilot caused such cidents following other side coin ex pressed extremely well letter Jefferson City MO modeler William Stodgell two-year-old might should purchase transmitter tray Besides 30-plus years RC have never used seen anyone else use neck strap So instead nit-picking faultfinding criti cism think Airtronics deserves highest praise Vanguard FM transmitter have given us radio will enable us fly safely high-interference areas oth ers will noteven new radios adver tised being ready 1991 Airtronics has also given us radio will operate up three hours per charge making virtually impossible run down batteries dur ing average afternoon flying session have honest presenting package no-frills no-bells-and-whistles radio have jacked up price just because works others will What could manu facturer promote safety contrast some manufacturers have contin ued cranking out selling radios cant re ject pager interference cant reject 31M interfer ence will able reject 23-channelsyndrome interference 1991 beyond have radio will reject some types interference stick bunch bells whistles average Sunday flier does need want charge enormous price give us radio might run over hour half per charge Sure Airtron ics has radios like too want least have given us choice long time no else did Several years ago bought super radios bought least-super available time would give dual-conversion receiver PCM made mistake run ning preflight test see just long would operate per charge first day out wiped out brand-new airplane because overflew transmitter battery Obviously hoop de-doo fail-safe did save dayor plane either After found out just long would go per charge always timed radio time stopwatch also checked battery pack ESV expanded-scale voltmeter RMcM meter between flights recently re placed original battery pack transmitter SR series 700 pack Expensive yes would fit tight battery compartment just like 500 increased safe flying time per charge little over three hours instead original limit just over two hours So now dont have worry about batteries either still have no-good bells whistles contend So instead nit-picking good manufactur ers product pieces use space Continued page 16 second time Ive written first regard in-flight stab failure suppose could classify letter complaint want stress enjoy column very much think should contin ued means However resent space devoted publishing someones criticism Airtronics Vanguard transmitter agree anyone turning transmitter off trying adjust trim has committed stupid mistake also feel just because several fliers have done does point finger stupidity manufac turer rather points fact can make stupid mistakes perfect person walk earth crucified anyone afraid making mistake simple fix remove plastic switch

Besides 30-plus years RC have never used seen anyone else use neck strap So instead nit-picking faultfinding criti cism think Airtronics deserves highest praise Vanguard FM transmitter have given us radio will enable us fly safely high-interference areas oth ers will noteven new radios adver tised being ready 1991 Airtronics has also given us radio will operate up three hours per charge making virtually impossible run down batteries dur ing average afternoon flying session have honest presenting package no-frills no-bells-and-whistles radio have jacked up price just because works others will What could manu facturer promote safety contrast some manufacturers have contin ued cranking out selling radios cant re ject pager interference cant reject 31M interfer ence will able reject

over hour half per charge Sure Airtron ics has radios like too want least have given us choice long time no else did Several years ago bought super radios bought least-super available time would give dual-conversion receiver PCM made mistake run ning preflight test see just long would operate per charge first day out wiped out brand-new airplane because overflew transmitter battery Obviously hoop
