bat teries 48 nominal volts airborne pack eight transmitter 96 volts As fly both packs put out about 250 milliamperes cur rent fairly constant nominal voltage 500 milliamp-hour airborne pack should operate 250 milliamps two hours flying Just before pack about run out juice voltage begins drop slightly 12 volts per cell nominal 11 volts low cell can safely used would 44 volts airborne pack about 8% drop voltage regular voltmeter no good checking Ni-Cd packs two reasons First unless put voltmeter across pack receiver transmitter turned voltmeter will give false reading voltmeter has very high internal resistance put leads pack sitting bench hooked thing no cunent will flow batteries nearly-dead pack might show nominal volt age Second its difficult read small differ ences voltage talking about regular voltmeter Expanded-scale voltmeters solve both prob lems As might guess scales expanded read about 43 53 volts alrborne packs 86 106 volts trans mitters also have built-in load resistor

bat teries 48 nominal volts airborne pack eight transmitter 96 volts As fly both packs put out about 250 milliamperes cur rent fairly constant nominal voltage 500 milliamp-hour airborne pack should operate 250 milliamps two hours flying Just before pack about run out juice voltage begins drop slightly 12 volts per cell nominal 11 volts low cell can safely used would 44 volts airborne pack about 8% drop voltage regular voltmeter no good checking Ni-Cd packs two reasons First unless put voltmeter across pack receiver transmitter turned voltmeter will give false reading voltmeter has very high internal resistance put leads pack sitting bench hooked thing no cunent will flow batteries nearly-dead pack might show nominal volt age Second its difficult read small differ ences voltage talking about regular voltmeter Expanded-scale voltmeters solve both prob lems As might guess scales expanded read about 43 53 volts alrborne packs 86 106 volts trans mitters also have built-in load resistor

operate 250 milliamps two hours flying Just before pack about run out juice voltage begins drop slightly 12 volts per cell nominal 11 volts low cell can safely used would 44 volts airborne pack about 8% drop voltage regular voltmeter no good checking Ni-Cd packs two reasons First unless put voltmeter across pack receiver transmitter turned voltmeter will give false reading voltmeter has very high internal resistance put leads pack sitting bench hooked thing no cunent will flow batteries nearly-dead pack might show nominal volt age Second its difficult read small differ ences voltage talking about regular voltmeter Expanded-scale voltmeters solve both prob lems As might guess scales expanded read about 43 53 volts alrborne packs 86 106 volts trans mitters also have built-in load resistor

OK time saved plane Daves advice about using expanded-scale voltmeter should heeded Sailpianers sure ESVM works heres quick non-technical explanation Just about radios nowadays use four nickel-cadmium bat teries 48 nominal volts airborne pack eight transmitter 96 volts As fly both packs put out about 250 milliamperes cur rent fairly constant nominal voltage 500 milliamp-hour airborne pack should operate 250 milliamps two hours flying Just before pack about run out juice voltage begins drop slightly 12 volts per cell nominal 11 volts low cell can safely used would 44 volts airborne pack about 8% drop voltage regular voltmeter no good checking Ni-Cd packs two reasons First unless put voltmeter across pack receiver transmitter turned voltmeter will give false reading voltmeter has very high internal resistance put leads pack sitting bench hooked thing no cunent will flow batteries nearly-dead pack might show nominal volt age Second its difficult read small differ ences voltage talking about regular voltmeter Expanded-scale voltmeters solve both prob lems As might guess scales expanded read about 43 53 volts alrborne packs 86 106 volts trans mitters also have built-in load resistor draw about 250 milliamps packs voltage being read gives true reading packs condition So Dave says check batteries field find pack red after 15 minutes flying know something wrong Either something causing excessive drain Daves case theres weak cell pack brings up other indispensable tool dealing Ni-Cd batteriesthe discharger cycler Lets assume have 500-milliampere-hour pack suspect its weak give usual 12-hour charge plug ESVM reads 48 volts slightly higher everything fine question long will go before voltage drops red 44 volts know 250 milliamps discharge current should take about two hours So start stopwatch plug ESVM stand couple hours watch ing meter go down because essential let pack discharge below 44 volts cell rever Continued page 143 ALL PURPOSE FOAM CU1TER Hands Off Cut II
