UDI 818S Falcon Quadcopter English manual?

I just purchased a udi 818S Falcon Quadcopter with FPV remote for my son for Christmas. Looks awesome! I looked at a lot of them before buying but I liked this particular controller with the FPV screen the best. Price was reasonable, actually over $100 less than most other places I saw it advertised. Just One problem- everything is written in Chinese! I assumed since it was being sold and shipped to a customer in the US that I would get a US ready product. This was not the case. Does anyone know where can I get an English manual for this? I looked on the internet and found nothing. Help!
