long time ago February 1985 matter fact time enquired anyone knew . better spend same total electrical power twin-motor installation versus single motor effect wondered two props better assuming same power expenditure Several readers kind enough respond hut opinions varied However Yesses outnumbered Nays I-dont-knows Well still am sure what answer However whatever reason can say twins showing up more Electric flying field often natural part Scale project theyre fun theyre easy implement readers have enquired about installation details thought Id share some answers everyone general best way wire twins series means positive terminal motor connected negative terminal second motor positive terminal second motor negative terminal first motor new combined motor leads two wires connected remainder system installationbattery fuse switch etc Just motors connected series also individual battery packs Thus motor normally runs example 12 cells two series-connected motors will run total battery 24 cells two twelve-packs wired series Hmmthats full case two distinct advantages series-twin installation total current drain battery same single motor very efficient motors batteries connected parallel other reasonable way configure twin total current drain would double bad news exception thiswhich Ill cover next month Wiring losses increase square current such losses would increase factor offour parallel-wired system Fuse rating would have doubleand dont know get suitable small fuses rated 40 amps addition switches speed controllers would gasp help under such tremendous currents recommended wiring diagram twins shown includes speed controller sake completeness want On/Off switch simply omit controller wiring Whatever custom particulars instal lation some provision
