Deletion of T-Rex (RC helicopter)

Comment: For the level of detail in the article, I find it surprising that there aren't | reliable sources providing some of this. There are a lot of links to buy it, and there are a few youtube videos showing people flying them too. I found a reference in a book ({{ISBN|0857296345}}) (can't see full content) to the model. It's hard to find references because the "t-rex" name is so common. I am concerned about original research in the article, but I'm leaning keep because I think there's more here beneath the surface. I regrettably can't find anything slam-dunk right now though

Comment: The cited German booklets probably provide notability for two specific models of this model helicopter, but not for the line as a whole. And the other cited sources cannot carry the article as a whole; there's not enough there to meet
