I finally got the blue cage/frame (see my revenge posts) installed on the NB4+.




I can't speak for anyone else...but, at least to me, the blue looks MUCH better than the usual four color options (black, red, gold, & purple) that are available from all the other sellers.

That being said, I did discover something 'interesting' when installing it. For those who've already purchased/installed these on their Noble radios, you probably already understand. Some of the sellers install thin neoprene/rubber pads on the insides of the pieces, and others don't (I'm guessing the OEMs don't install them at their factories). For anyone having received a cage/frame without the pads (as mine came), when you go to install it, you'll quickly discover the cage/frame "moves" up/down/left/right/forward/backward, as there is approximately 1.5mm of play in all directions...thus, the very reason some sellers install the pads. If you install thin neoprene/rubber pads to the inside face of all four pieces, this will fix the problem.

I forgot to take photos...but, what I used was the thin (0.98mm w/ both sides of the adhesive cover paper still in place) "electronics mounting" strips that come with many RC kits. I cut multiple pieces (2 for each side piece, 4 (2 side, top, & bottom) for the front piece, and 4 (2 'upper' & 2 'lower') for the rear piece), peeled off one side of the paper, and stuck them in the 'appropriate' places on each piece. In installing the cage/frame on the radio display housing, the pads compress just slightly...enough that they provide just a minor amount of "resistance" to the 4 screws, which will help prevent the screws from backing out (ie. you won't need to use threadlock on the screws). I purposely didn't peel the paper off the other side of the pads, to make removing the cage/frame easier...but, if you want to make 100% certain it doesn't move, you can always peel off the paper, which will adhere the pieces to the display housing.
