Mega Baja Monster RTR w/26

Losi's Mega Baja Monster Vehicle with M26SS engine and JR XR2i Radio System.

At a Glance

The Mega Baja™ is one of the most powerful and durable nitro powered monster vehicles Losi has to offer. Based on the proven dual-deck aluminum chassis design and rock-solid 4WD drivetrain, the Mega Baja puts Losi’s years of innovative research and design in your hands. A 3-port Losi M26SS engine produces big block horsepower and torque, routed through a shift-on-the-fly 2-speed automatic transmission for stump-pulling power and top speeds approaching 40 mph. Power reaches the ground through a bulletproof drivetrain utilizing metal-geared differentials front and rear, housed in cast-aluminum cases for serious durability. The Mega Baja also boasts revolutionary Mega Shock suspension, letting you aggressively assault terrain that would leave other trucks stuck in the mud. Twin metal-geared steering servos provide plenty of torque for pointing the massive off-road tires in the right direction, and you stay in precise control the entire time with JR’s programmable XR2i computer radio system.

The Mega Baja RTR comes with a JR XR2i computer radio system, Spin-Start handheld starting system, receiver battery pack and wall charger, glow driver and a basic tool kit so all you need to complete is a 7.2V battery and charger for the Spin-Start, 8 AA batteries for the transmitter, a Losi fuel bottle (LOSB5201) as well as Losi recommended Nitrotane model fuel.
