I have one gws rx that I really like, its a larger black 6 channel one, but I have not had a lot of luck with the Naro or Pico ones. I have a dickens of a time getting those hooked up correctly so that it all works. Almost no instructions, and I run in JR, so there is even less for that. I just have to try everything and gradually get one piece after the next to work until I can finally use the thing. But the pico is the only one I've found that is light enough for indoor RC and still within my price range. A bit more documentation would be nice.
