Anyone Building/Flying Quadcopters/FPV Racers?

So I am looking to get into quadcopter flying, specifically the mini-250 class that are mostly used for racing. I don't plan to race or anything but I just want something that goes fast and is fun to mess around with. Anyone on sythe messing around with these things?

Kit I am looking at:

FPV kit:

I actually just bought a UDI U839 to fly around my apartment, but haven't had a chance to try it out yet.

 

Bump!

 

Nice, I've always wanted to build an FPV for when I make/get something like this -v
