The E-flite UMX Ultrix BNF Basic Electric Airplane with AS3X & SAFE Select is novel, redesigned "Ultra Micro eXtreme" delta wing with aerobatic and 3D capabilities that delivers a flight experience as unique as its appearance.

This twin brushless motor-powered, delta wing airplane excels at smooth sport flying, basic aerobatics and even aggressive 3D — all in the same flight. It features an incredible power-to-weight ratio with hovering capability and unlimited vertical performance. Differential thrust adds yaw control and the ability to perform advanced aerobatic manoeuvres including harriers, amazing flat spins and many more. The durable EPP construction makes this one of the toughest ultra micro models available. The included Optional-use SAFE® (Sensor Assisted Flight Envelope) Select technology makes the Ultrix easy enough for low-time pilots to enjoy, while still being exciting and involved enough for experienced fliers.
