BIGGER FLIES EVEN BETTER!
Soon after it was introduced, the UMX™ Ultrix™ turned into one of our most popular ultra-micro designs. There was, and still is, absolutely nothing else like it! The unique delta wing design stands out at smooth sport flying, basic aerobatics, and even aggressive 3D — all in the exact same flight. This scaled-up version provides the exact same unique capabilities AND the advantages of a bigger size. It's easier to fly due to the fact that it's easier to see and handles more wind. The Ultrix 600mm also uses more typical 3S 800–850+ mAh batteries and includes an optional-use set nose wheel so it can launch from and arrive at smooth surface areas. Like the original, it has an incredible power-to-weight ratio for hovering ability and limitless vertical performance. Differential thrust includes yaw control and the ability to carry out sophisticated aerobatics including harriers, remarkable flat spins, and more. Plus, the incredibly resilient EPP airframe is totally factory-assembled so the Ultrix can be all set to fly just minutes after you open the box!
