I just bought a car made in china. it is a 1/10 scale 4 wheel drive shaft 
driven buggy. The manual only says 2 1/2 hr. Is this normal charging time 
for these batteries? and also says that the transmitter 800mAH in 4 hrs. It 
only came with the charger for the 7v battery on the car.The transmitter has 
a connection on the bottom. Is this optional if I don't want to use the 8 AA 
batteries? Or do I still have to charge it in adition to the 8 AA's? This is 
my first time owning one of these R/C cars, thanks for your help.
