but this Hubsan X4 is really really worth it. I have bought at banggood.com, it takes around two weeks until you receive it, but is not pricy. My transmitter was faulty but they sent me another one really quick.
It has two modes, normal and expert. You don't normally need the expert mode unless it's really windy outside. This quad is small but it flies amazingly well!! It is super fun!! I recommend to purchase at least a 5 battery pack (380mAh) to enjoy flying for a while. The duration of a battery is around 7 or 8 minutes, and it takes 45 minutes for full charge.
I also recomment to buy some extra propellers, and the 5 in 1 charger battery wire. It takes about 3 or 4 hours to charge them all with the wire, but you don't need to check them every 45 minutes, it's just useful.
Please take a look at this video before flying, these tips will save you some bucks for sure!
After some crashes you will notice the quad is not flying properly, or it doesn't stand quiet when trying to keep it at the same spot. You will need to check the propellers haven't been bended, and calibrate it in order to (probably) solve this. Take a look this video to see how to do it:
I have also bought a soldering iron, tin, and a third arm in order to fix when the motors brake. It is really easy to do, and will allow you to continue flying in no time!
