It's total crap, avoid. The range on the latest version (red PCB, original had green) is about 20 meters... maybe. Always dropping out the sky. When I looked inside the transmitter the wire that passed for an antenna was ~26mm long. For 2.4Gh you need a minimum of 31mm (1/4 wave) for decent performance. I added on a bit of wire making a total length ~94mm (full wave), brought it out and cocked it to the right. Works decent now.
I tend to abuse my stuff so I had a spare set of motors. I ended up bending a shaft and also threw a pinion. When I pulled out my spares I noticed they no longer have opinions on them. Now I wait for some pinions.
It flies fine when it stays in the air, but I regret buying it.
