SAB introduced the Direct Drive on this class of helicopter and as you may know, this has been a huge success However, in pursuit of improving performance, we determined that the Direct Drive could no longer be the correct solution for the highest of performance. The evolution of the RAW 420 will use a motor belt drive. This is how the RAW 420 Competition was born. Lighter, faster, more flexible in the selection of the desired head speed at a higher performance level.
