It must have been mid 2014, I want to try how to fly helicopters. So I bought a very small one, the Blade mcpx BL. BL means brushless motors for both the main rotor and the tail rotor. I used a big set of batteries, because with one battery I have a flight time of 4 minutes. Also, flying helicopters is very different from flying airplanes, so I had to buy a lot of spare parts. I think that every beginner with helicopters has to go through this.
