I'm a wee bit disappointed in mine, but I did order another. I have mine mounted on a F330 quad, with a Naza Lite w/GPS. Running Spektrum radio gear. I too was impressed at first, walking around the house, with it running on my desk. However in flight, I honestly can't see much difference between it, and one of the iddy biddy micro 200mw TX's. I also have some strange jidders, diagonal tweaks going on? Tried with both Skyzone goggles, and Fatshark Attitudes. Started on Fatshark default freq, then changed both goggle and TX to F band, channel 4 (5800 mhz) Not much difference. Also, I think it may have blocked my Spektrum radio gear. Two times, while only 50-75 yards away, the quad just very nicely landed and turned off it's motors !!!! No response from radio. I don't have any fail safe setup. Once I walked a bit closer, was able to arm the motors and continue flying, but again, in a different direction, same thing happened. I have not tried any distance with it since. I actually wondered if my new Naza Lite had some kind of limits setup, but I see nothing in assistant. Really strange cause both times when it landed, it was nice and slow, like I had done it myself, no falling, etc. I will experiment more when my other one gets here, on a different setup/quad, in case my problems are with my installation. Also have a new Black Pearl monitor coming, so it should match up with it. And after it cools off some, and I get a blood transfusion (joking, missing some from the skeeters here in SW Florida):tennis:
