This is the FX070C MD500 scale rc I got at Banggod.com earlier this year. I am flying at an rc airfield close to me.
The heli itself is fun to fly, but I'm looking at replacing the gyro because it seems twitchy at times, and replacing the receiver so I can use a better quality radio. The heli nor transmitter give no warning as to when the battery is low; it just falls from the sky if you drain it. I have timed it and came to an average of 6 minutes for a flight (style like this video) from take-off to when it completely shuts the heli off. So I now fly with a timer for 5 minutes or so. All together worth the purchase and it is quite durable. I did receive the heli with a broken swash plate, and a wire in the transmitter unsoldered. Banggod replaced the swash plate for free and I fixed the wire myself.
