Doug,

In fact each of those packs has 20 cells but only 5 (stacks of four each) are in series... The Actro 32-3 is used in the Ion helicopter with an Actro 32-3 motor with two 5s4p packs in series routinely. The speed controllers generally used with this set up have max amperages of 70 to 80 amps or so. It isn't obvious to me why the amperage draw of a 17X12 propeller should be more than a 1.5 meter rotor (though the rotor is geared, I understand) That is why I asked the question posed to start this thread.


I have emailed and left phone messages at Hobby Lobby for two days now with no reply...that's why I came to the forum here, looking for knowledge<G>
