Drones Suitable for Training with Low Risk

There are at least two drones suitable for beginners, they don't have camera, these drones are only for training and having fun.

So you have SKYWALKER MINI

It has two speeds (Low/High)and can do two stunts.
As you can see this drone is very well protected you can hit the walls/ground/ceiling without damaging it.

Its very tricky to control because its so small (smaller the drone more difficult it will be to control).

Then you have the second drone SKYWALKER

Yes it looks the same as before but this is bigger and easier to control (bigger drone, more stable).
It has also two speeds (Low//High) and has a special button on the controller (Fly/Run) that if pressed makes the drone without power to fly.
Now you can race with other R/C cars ;)
So... to start these two options are great, because of its resistance and flexibility.
