Best Option for 5" Alien
This, plus the universal PDB and 4 arm boards are what I went with for my 5" Alien build. Unlike the Impulse RC Alien LED plate (and many others) this has plenty of room for an antenna or pigtail to pass through. The pre-programmed colors and patterns are cool enough, but being able to program the settings yourself is a huge bonus. Having this on your tail and an arm board under each arm really makes your quad eye catching. Weight addition is negligible, and the wiring is extremely simple (with the universal PDB not sold here). The aforementioned PDB can either mount in your stack or taped down to the rear of the stack (or anywhere I guess). Without that you're going to have a very odd wiring situation, so I don't know why RR passed it over. The arm boards can easily be attached via 3M VHB tape, or even regular foam tape if you want something less permanent. Heat shrinking them is completely unnecessary if you have landing pads or skids and only dulls the LEDs significantly. I highly recommend picking up the combo that I did or even just the tail board if you're looking for an outstanding and easy to set up LED system for your quad.
