RE: Wall Chargers.... how large of a pack will still work?
the math is very simple
wall charger have 2 out puts. one for the RX and one for the TX
Battery Charger for Tx 11.6V 65mA/Rx 5.8V 150mA, 1000-1400 mAH, JR
so for the RX batt with 2700Mah NI-THwould take 2700/150=18H
BUT - the walll chargers are for NICD batt only!!!!!
i suggest you to get a "smar" digital charger for 40-60usd&
it would charge your LIpos, Nimh,Nicd and more:
