E-Flite Ultrix 600mm BNF Basic

Quantity: Only 1 left in stock.




Soon after it was introduced, the UMX Ultrix became one of our most popular ultra-micro models. There was, and still is, nothing else like it!

The unique delta wing design excels at smooth sport flying, basic aerobatics, and even aggressive 3D all in the same flight. This scaled-up version offers the same unique capabilities AND the advantages of a larger size. Its easier to fly because its easier to see and handles more wind. The Ultrix 600mm also uses more common 3S 800850+ mAh batteries and includes an optional-use fixed nose wheel so it can takeoff from and land on smooth surfaces. Like the original, it has an incredible power-to-weight ratio for hovering capability and unlimited vertical performance. Differential thrust adds yaw control and the ability to perform advanced aerobatics including harriers, amazing flat spins, and more. Plus, the extremely durable EPP airframe is fully factory-assembled so the Ultrix can be ready to fly just minutes after you open the box!
