Licensed Baja-Bug-styled desert-buggy body on independent front+rear suspension -- direct competitor to Axial's RBX10/Yeti class. Shares Losi's "U4" rock-racer platform naming with the solid-rear-axle Hammer Rey U4 (LOS03030) but is a mechanically distinct, separately-sold real product (different suspension architecture, motor, battery rating) -- not a duplicate.
Nobody has written this up yet. The spec sheet above comes from the manufacturer; what actually fails first on a Lasernut U4 — and what owners do about it — only comes from people who run one.
