Helicopter Great Wall RF of two propellers

If you do not have experience in flying toy helicopters, do not buy this. Do not buy either of two propellers.

I write this because this helicopter is very nice but pretty hard to to handle. When you have four vanes for stability as the rotation, in this the pilot has to be correcting this defect.

This is a good toy helicopter. The control works with Radio Frequency, IE, You can fly it in open environment. The problem is that any wind can take you away.

Spin stabilization is done through the tail rotor (Figure above), Unlike the four-propeller models.

This is the only helicopter that I've seen that can remove the battery. Not that it's any advantage. Flight autonomy is about 10 minutes.

There is the option to recharge the battery via USB or using batteries of the control. As with any helicopter.

In details, below, the control with four channels. Up/down, Tilt left/right, forward/backward and rotate left/right.

The control has these buttons at the bottom to calibrate the Center. It is a very complete helicopter, Although hard to drive primarily on indoor environment.

Bought in Focalprice in a promotion for $ 20. Now it's over 40. For those who want to, I leave the link:

  1. I know this if off topic but I’m looking into starting my own blog and was wondering what all is needed to get set up?
    I’m assuming having a blog like yours would cost a pretty penny?
    I’m not very web smart so I’m not 100% certain. Any tips
    or advice would be greatly appreciated. Many thanks
