since month several photos show some how-to Astro gear drives Ive using white lithium grease years have excellent results Im sure other lubes would fully satisfactory can attest firsthand Anyway grease available auto supply stores comes too large container modeling use its very nsive might find some use family wheels example Ive found works great squeaky car door hinges catches back gear drives preferred approach dip toothpick similar small stick grease dab small drop onto gears shown Spin drive band spread grease over teeth practice takes very little job Excess grease will simply thrown off run motor theres no point overdoing next thought Id like pass along After youve lubricated clean new gears want keep way Its important keep dirt grit out gearbox because such contamination can cause rapid gear wear too photo shows bottom nose-end view geared 25 cobalt-powered Seniorita after few flights off wet grassy field spots underside small mud splashes Notice gearbox opening

higher lower capacity lets use number example number represents amount charge battery can delivernot unlike size numbers use nickel cadmium packs current/time product available battery before tenninal voltage begins drop rapidlyusually below 11 volts Note has nothing cold-cranking amps numbers manufacturers like hype observations experience car batteries begin lose capacity long before problems starting car appear its easy lulled sense security about condition battery actuality car batteries seem lose capacity ampere-hours right beginning use some can dramatically deteriorate ever fully run down Thats like keep good ol fashioned maintenance-needed types car Anyway lets say start out new 50-Ah battery lets say have plane 14-cell 1 2-Ah pack placelike Seniorita Think battery two seven-packs Lets say using constant-current charger have several devices find usually operate about 60 percent efficiency somewhat lower means charger takes power delivers battery undercharge Now lets collect use numbers airborne pack needs about 21 14 x 15 available volts during charge charge 45 amps charger delivering 21 x 45 about 95 watts 60 percent charging efficiency charger taking 95/060 about 158 watts car battery car battery has terminal voltage 12 volts therefore delivering 158/12 about 13 amps during charge-up particular motor pack might want read again really does take 13 amps car battery charge motor pack 45 amps specific pack described Yup Thats right So flights car battery good About 14 ideal worldif want spend night field ideal difficult find very few folks want sleep flight line love hobby notwithstanding actual practice car battery voltage does remain 12 volts during discharge instead drops terminal voltage during use happens chargerif its constant-current chargerwill automatically increase its current intake maintain output charge thus depleting car battery faster under conditions charger efficiency generally drops takes current make up declining efficiency its downhill way thereafter folks Getting further reality average car battery like yours probably like-new condition may very well year two old half capacity still able start car just
