thats about extent line time month has good year new Electric products want share some information few new Astro 1 lOD charger new Aveox motors/controllers some micro RC-E stuff speed control Steve Neu new Astro 1 lOD D digital good working product told Bob Boucher head modeler Astro numerous Astro chargers Ive used over past two decades may finest effort ever 1 lOD relatively low-cost simple-to-operate microprocessor-based peak charger 18 cells simplest terms just push button dial up desired current wait charger its thing Ive exercised unit shop field well road field Ive come rely heavily its reliable performance bench-tested 1 lOD using highcapacity lab-type power supply charged 4- 7- 10- 14- 18-cell packs about 5 amps varying power supply 11 15 volts monitored input voltage current output pack voltage current calculated efficiency over range latter varied 70% 90% various conditions greatest efficiency being displayed largest cell counts worst-case internal dissipation under conditions less 14 wattsvery low means internal heating minimal although front panel can get quite hot unit running direct sunlight Best keep shaded maybe Astro should consider alternative reflective panel finish impressive thing output charge current constant its set value over total input voltage rangeit doesnt matter car running youre using its battery source set current holds its value no matter cell count except 47 amps available full 18-cell count limit no real problem all-conditions stable output current means dont have diddle currentcontrol knob during charge maintain chosen level pack peaked charger reverts trickle-charge output condition 1 lOD has built display readout housekeeping displaying motor pack voltage showing elapsed charge time showing Ampere-hours charge delivered display also advises no pack connected charge completed some other incidental info well 1 lOD lists $15995 its readily available discounted good working product very reasonable price should perfectly satisfactory charger sport E-modelers Its disappointments lack beep completion charge something Ive become accustomed on/off switch like leave chargers wired 94 Model Aviation several faces Astro 1 lOD charger Readouts include optional personalization current level pack voltage elapsed time accumulated Ampere-hours others Author feels may Astros best charger Bob Afflerbacks Twin Mustang has two geared 406 13 x 8 props 40 14 Ah SCRs two speed controls Flew very well 1995 LVRCS meet Steve Neus micro FAI speed control tiny jewel design operation Text has details address car power system 1 lOD supplied clips connect auto battery also feel input output cords could bit longer Ive added connectorized extensions practicality 1 lOD available customized display indicating ownership reads out Property Bob Kopski display unit charging pack can have similar customization $20 additional order direct Astro Think charger vanity plate Its true confessions time know first Ive seen others it makes no difference thrill get new Aveox 1409-2Y turning Sonic-Tronics 13 x 7 via Astro gears 57-ounce E Motiontaking latter straight upout-ofsight Id allow Except first Electric successes twenty-some years ago Ive felt such E modeling excitement before thrilling feeling fast vertical ascent very close endorphin bliss motor its companion controller represent latest product versions Aveox Im indeed fortunate have opportunity try out Im delighted performance product now own two em also fly 14124Y Now understand Aveox products recently took 8 top 12 places European Electric Champs Im told some European manufacturers pursuing own brushless designs because conventional brushed motors have clearly fallen dominance highly competitive arena may case change go under current Aveox product line includes rather large number product variations including several physical motor sizes/power levels several winding options latter include choice delta wye winds windings count may bit confusing Aveox can supply listlsummary options typical performance various props various cell counts effect can pick choose find whats just right flying interest choices allow optimization its characteristic brushless design operation given choice operates very well over very large application range much conventional motors accustomed several new companion controllers select too 1409 represents particular physical motor case size power-handling capability close physical match popular can motors its much bigger power handling 900 watts rating 1412 has 1200-watt rating 2 means just two turns magnet wire its three windings keeps motor resistance incredibly low 028 ohms Y designates nature internal winding connections E-Motion fueled 10 cells peak current drain about 40 amps gives power input about 400 watts loafing compared 900-watt rating Nearly power goes prop motor/controller runs incredibly cool As usual have cooling air path through airplane conventional motor installed same model running much less input power lands too hot touch Incidentally retrofitted second 1409 system Sig Wonder too goes vertical often let E-Motion climb speck size fly aerobatic glide back down power up again etc Typical flight times regimen exceed 10 minutes dead air vertical performance available beginning flight continues very near end flight because motor stays cool efficiency high Thanks Aveox head David Palombo Im sold performance brushless need help call Aveox friendly folks will gladly assist Dick Miller every-other-month E columnist Flying Models

Steves other personal philosophy use BEC products includes option Brush dust insidious superfine black powder spews conventional motor case openings deposits itself like fine paint over anything thats motor compartment Its actually brush material wears off during motor operation youve pursued know stuff just does want come off seems have particular affinity silicone insulation high flex wire use balsaYou can something preemptive about latter Ive found coating new balsa motor compartment Ambroid allows collected brush dust wiped off easily suggest coat fine sanding another coat big help mentallygray balsa very disturbing Two recent experiences have extended view-screen Electric perspective thumbing through latest copy popular modeling supply catalog came acrossof thingsear plugs take aimed Electric modelers Next old friend former active modeler happened field recently after several years absence seen Electrics earlier years no recent ones flying Juice sort Daddy-sized E Motion geared Astro 25 15 cells Its much like newer designs impressive compared directly its very aggressive performer its own right attaining very high angle attack headwind its variable-camber option deployed also has very wide flight speed envelope power power off very aerobatic friend watched rather excitediy exclaimed fantastic impressive compared years-ago Electrics catching himself commented yeah way about expensive must dont know what expensive means know its relative term mans cheap may anothers expensive also feel no hobby escapes situation friends such pursuits amateur radio fishing photography participating sports full-scale aviation sailing gamblingand on Any pursuits can expensive depending point view highperformance other Electric fits right too Keep open mind Someday Electric may best bargain youit may save flying field Tell just expensive lost flying field Thus ends beginning issue/column another year Since youll have just about right time let wish sincere happy
