The Full-Throttle Liberty of AVC® Technology

The Full-Throttle Freedom of AVC® Technology
The receiver's built-in AVC® (Active Car Control®) traction control system works behind the scenes, making hundreds of throttle and steering changes per 2nd, so more of the motor's power is translated into ballistic speed and velocity rather of simply flying dirt. The patent pending AVC system adds a level of performance that just cannot be found with any automobile from any maker besides Horizon Pastime. Like traction control in your major automobile, you can activate or shut down the system on the fly and change the level of stability based upon driving conditions. Any RC automobile can go quickly and with AVC you can go much faster while keeping optimal 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 travel at 90MPH throughout the desert, but also have the torque and driveline strength to get over rock developments that look impossible to navigate.

One reason Casey Currie and his U4 race truck works so well with the Rey platform was the featured independent suspension in advance and solid axle in the back. Naturally with Losi, drivers get as much detail as possible while protecting the performance and sturdiness the Rey platform is known for in the RC racing neighborhood. The combination is a one-way ticket to triumph after triumph, reproduced for the desert and prepared to impress.
