I built an emax nighthawk with the cc3d board, got it dialed pretty good, but I'm not into the FPV racing. More just for farting around with the goggles on. Picked up a Naza lite GPS the other day, and gotta say I am so much happier with it. Very comforting being able to hover in one spot and not worry about drifting away while I put the goggles on or take them off... Which I like to do. Not really comfortable taking off and landing with them in yet. Got the gains close to where I like in the few flights I've had with it, but now it's snowing heavily here, and I had to dust off the nano QX fpv for some indoor fun!
