The receiver's integrated AVC® (Active Automobile Control®) traction control system works behind the scenes, making hundreds of throttle and guiding modifications per second, so more of the motor's power is equated into ballistic speed and velocity rather of simply flying dirt. The patent pending AVC system includes a level of efficiency that merely cannot be discovered with any car from any manufacturer aside from Horizon Pastime. Like traction control in your full-blown car, you can trigger or shut off the system on the fly and change the level of stability based on driving conditions. Any RC car can go quickly and with AVC you can go faster while keeping optimum stability in all driving conditions.


Every weekend off-road racing motorist, Casey Currie's feet are touching dirt and the gas pedal. His career has actually taken him all over the world with a highlight being his threepeat at the Baja 1000 in 2017, 2018, and 2019.

Full-scale U4 race trucks are a unique breed. Not only are they expected to cruise at 90MPH throughout the desert, but likewise have the torque and driveline strength to get over rock formations that look impossible to navigate.

One factor Casey Currie and his U4 race truck works so well with the Rey platform was the featured independent suspension up front and strong axle in the back. Of course with Losi, drivers get as much detail as possible while preserving the efficiency and toughness the Rey platform is known for in the RC racing community. The mix is a one-way ticket to victory after victory, bred for the desert and ready to impress.
