The Walkera 83 deluxe nitro helicopter is the next level of remote control heli’s to arrive, it takes you to another level of control and experience with the belt driven tail system a huge leap forward from tail driven motors. Available here as a full RTF package with everything needed to fly this fantastic model straight out the box.
It comes with separate components like the Wk-G011 Gyro and Receiver unit to replace the more basic 4 in 1 controller seen in cheaper models, this enables you have separate units for maximum control. Whilst these parts are excellent quality it is very easy to swap them out and upgrade to components of your choice for even more control, giving headache free modifications in the future.
