The original release version of the mCX was designed to have the paddle shaped flybars. They built up inventory levels to support the replacement parts business at stores. Right before release, they changed the design to the tubular type. It was determined that the tubular style yielded better performance. E-Flight needed to get rid of all the paddle styles, so they were sent to stores. As supply of these paddle style flybars dries up, stores will begin to receive the tubular style. If you want to experiment with them, get them now... soon they will be collectors items!
