Anyone recognize these?
 

Hi guys, I'm a complete newbie to RC Helicopters. Please bear with me.


I recently bought two used RC helicopters, but they're not what I expected.


1.
It was cheap. 15€ for two medium sized rc helicopters. The guy told me all I had to do was program the controllers (he said I could do it in a car-key shop, even).
I thought it was a good deal.


2.
The package arrived and I notice the controllers didn't belong to the helicopters, and seemed cheap. But I thought they might work.


3. The helicopters don't seem to have a way of charging. I expected a USB port, but they don't have one.


4. They don't have a brand, apparently.


I thought it was a good deal.


Maybe you guys can help me identify what I've got and help me out.


Took some pictures. I can take more pictures. On one of the pictures, I detached a cable so you could see what it was.

Thanks in advance.
