Hi guys,

I haven't used my drone in a while and today I took it out to update it but my controller won't turn on (pressing once then again for a few seconds). I have connected the charger to it and a red light comes on with the 4 white LED lights but when disconnected the controller will not turn on. It doesn't charge. I have tried charging it for a few hours but no joy. Can anyone help? Thanks!

I've got the same problem, but in my case no lights come on with the charger.  If you find the solution, please let me know.  gerutzen@yahoo.com

The battery in the controller probably needs to be replaced.

Probably the RC battery is faulty.
I'd suggest you to send it in for further evaluation.
