i just got my aerohawk today and i looked at the wall charger and it says it charges at 350mah. i read here somewhere that the supplied wall charger takes 8 hours to charge. i am confused. as i see it it should be 2 hours for the 700 mah battery pack. what"s up?

You are almost right. The battery is not 100% efficient and you get heat generated while charging. So I would say you need 2 1/2 hours to get max charge.

I have invested in a multi purpose charger with a temperature sensor for overheat cuttoff. This means you can set it and forget it...

i agree

No...the (admittedly very bad) documentation with my Aerohawk stated that the battery packs should be charged for 2 - 3 hours, which is exactly what you would expect as the charger is rated at 0.5C.

is that 2 hours every time or just on the initial charge?

with all electronics or batterys i have read that for the first time charging you should let it charege for 16 hours and then let it be totally discharge(by flying) then charge again for 16 hours and this shall keep your battery good for the rest of its life this should make it last longer and give you full use of the battery and from then on n you can charge it for 2 hours or so.

The confusion is from the RADIO SYSTEM battery chargers vs the MOTOR battery chargers.

The typical RC system comes with a 50 ma rated charger for the 500 to 700 mah rated batteries... that gives you 12 to 20 hours to achieve full charge the first time around. Divide 600 mah by 50 ma and you get 12 hours.

The Aerohawk is a different critter. The charger is 350 ma rated and the battery is 700 mah rated... divide 700 mah by 350 ma and you get... 2 hours.

It is always assumed that 10% to 30% of the charge power output of the charger is wasted as heat. Thus you get 12 to 14 hours to charge a RX pack rated at 500 mah.... and can need 20 hours to charge a 700 mah pack. The Aerohawk's pack will need 2.5 hours the first chage then should be fine at 2.25 hours MAXIMUM for charging when you fly till the thing won't get off the ground.

Watch out for overheating the batteries when charing at the C/2 rate... you can explode the batteries if yopu excessively overcharge (especially if you started with a hot battery)
