I bought the 802 version for my FC40 FPV setup. I did a few things differently for my setup, but I have no regrets as it has been an awesome setup so far. I did post a list of items on another thread that I purchased for my setup. I'm not a fan of the screens that you have to power separately so I bought one with a built in battery. Its cheaper on Ebay if you can find it and the battery lasts 2 hours. Her is my list of parts.
