charging flight bat teries between flights since likely trouble-spot newcomer typical flight mini-electric motors will draw about two amperes current 30 60 sec means battery needs charged two ampere-minutes two amperes x -minute re minute etc juice does field charger provide necessary two ampere-minutes charge charger supplied MRC airplane package typical simple drycell charger contains four standard Csize flashlight batteries connected series obtain six volts charging terminals connected flight batteries current about two amperes pumped Thats exactly what current model flying remember Therefore charger attached -minute charge ampere-minute two amps x -minute obtained charger attached minute charge two ampere-minutes two amps x minute obtained Easy eh small 50 mAh flight batteries can theoretically take larger charge three ampere-minutes maximum after minute charging two amperes become rather warm further charging high rate can damage So its safest fast-charge 75% less maximum capacity tiny cells Slower charge rates safer course time charge up lengthened proportionately example half charge rate charge time doubled way converting conventional mAh milliampere-hour capacity ratings cells convenient ampere-minute rating easy As example cell rated 50 mAh can take charge 50 milli amperes 50/1000 amperes hour 60 minutes capacity therefore 50/1000 x

simple nice charger uses three C-size dry cell batteries charge current about 1 amperes charging time between 50 100 sec FE also markets slow charger FEs designation uses two D-size dry cell batteries Charging case much lower rate takes five minutes longer danger overcharging almost elimi nated simple dry battery chargers after little practice can begin tell long charge model needs given flight duration must course use watch shows seconds accurately keep track charge time simple dry battery charger does have two main shortcomings First since dry cells dont have lot capacity soon begin wear down necessitating everlonger charge times some point de pending upon much fly new batteries needed Second no ammeter measure charge current total charge put flight batteries cannot known degree ac
