Or, if the front motors don't work at all, you could send it back and get a refund, then buy another, better drone. I recommend the UDI R/C brands.

Well, you could try rewiring it so the current to those motors is reversed...

make sure the files are compatible.

Get a new battery. I had a drone that did the same thing. It's caused by a defect in lithium batteres; if you run them down for too long, they forget how to keep a charge, and only supply a very limited voltage for a very short time before dying. Or you could get a smart charger and run a maintenance cycle.

I would see about making sure no wires are short circuiting, then, if that don't work, try to replace the motor, or get a higher quality drone.

Or send me an email @ e.grames100@gmail.com, so I can give you more detailed instructions.

Replace it or splice a new one onto it. Usually you can get away with taking another wire and twisting it onto the old wire so it still forms a circuit. If you still don't know what to do, take a circuitry class. They'll teach you everything you'll ever need to know about what to do when a wire breaks.

You were at the end of your signal range? I dunno. sometimes they advertise, say 200 feet, but the transmitter takes so much power that the range ends up real small. That or your drone had a "programming issue". Also, all y'all know that there's this thing called a consumer warranty, and usually these things have it. All you do is mail it back or call the company witha complaint and ask for a refund. If they refuse, than that's their $#^!!. Usually they will replace it though. Unless its a "User Error".

Sounds like something was jamming your signal. I had a guy in my neighborhood do it to me, and I totally woulda built an EMP and fried his house had he not stopped.

Generally, 15-20 minutes of flight time is above average. My drones only fly for around 10 minutes off a full charge, even straight out of the box. I'd assume the charger in your drone has an auto-shutoff after a certain period of time, or at a certain voltage, so two hours is probably just fine.
