There is a forum right here on RCU for Nitroplanes customer support. I received a crushed wing panel on a Nitroplanes ARF and once I got ahold of the right person it was no problem at all. My new replacement wing came in the mail "pronto Tonto" no questions asked.

Here is the link to my original request here on RCU forums:

Send an email to RCU member "nitrostaff1" politely stating your complaint. John is a company rep for Nitroplanes here in the USA and he will get you going. Stick with the facts and leave your emotions out of it and you will definitely get a reply from John. He has more pull than some tech support phone guy in HK/China.

Hope this helps!
