I see, I've been told that the black pearl 7ch is perfect with the IRC 600. It doesn't seem that the rx-5802 includes a internal battery or HDMI in
you are correct, people say the 7ch version of the BP receiver works much better than the 32ch. I was looking at it purely from a cost perspective: the BP 7ch is around $210 at all the places I've seen it, and the RX-LCD5802 can be had for about $150 if you're willing to wait for an overseas shipment like from Aliexpress or DX.com
The Rx-LCD5802 DOES have an internal battery good for about 3+ hours (confirmed by me) although you'll need to buy or make a power cable since it doesn't come with one... it comes with a power cable that has a funky plug on it, so I snipped off the weird plug and patched in an old DC adapter I had sitting around that matched the specs... works great and was free.
As for HDMI you are correct - I didn't realize the BP had a HDMI in although honestly it never occurred to me to use the display for anything other than FPV for my Phantom so I never expect to be needing an INput. The RX-LCD5802 does have standard A/V input and output which the BP also has, so you can go out to or come in from a RCA video source (blah - who uses RCA anymore)
so that seems to be the major difference and deciding factor when making this decision... is a HDMI input on your FPV receiver worth the extra $50?
