AFR, charge your batts 24 hrs for da 1st charge, then 14 - 16 hrs after dat if you have fully ran dem down flyin'. what I like to w/ a new batts is do this 3 times B-4 puttin' into service. Since you prolly don't have a cycler, just charge dem w/ da included wall wart chgr and unplug from plane and tx , extend the antennae fully on tx, turn on tx and plane and leave on overnite . this is the po man's way of cycling yo batts. do 3 times and you should be ready. Always do a good pre-flyte and start establishing you're secret account for yo next planes H.T.H. Rob
