Apache 3ch helicopter

[charliejh]

I purchased an electric apache Ch helicopter via the internet.After charging it the first time i went to the back yard to practice flying.When i moved the controller nothing would happen.After a few minutes it seemed to kick in.I practiced for about 10 minutes without incident.I was hooked.After charging again i went to the yard for more flying time.When i moved the controller again nothing happened.The light on front of the copter is lit,and the controller light is on,but nothing happens.I contacted the internet supplier to send it back for an exchange and he told me if i flew it i bought it.Does anyone have any ideas on what might be wrong?The instructions they supplied with the copter are very vague. Help!
