The Losi TENACITY TT Pro 1/10 4WD Brushless Ready to Run replicates a Brenthel race-inspired trophy truck in a RC short course truck. Featuring a 4mm 6061-T6 aluminum chassis, Spektrum Smart 130A ESC, and officially licensed Falken Wildpeak MT tires, this truck delivers speeds over 50 mph with 3S LiPo power. Designed for brushless RC truck enthusiasts, it combines durability and advanced electronics for track racing or backyard bashing.
Performance
The TENACITY TT Pro achieves speeds exceeding 50 mph with a Spektrum Firma 3150kV brushless motor and Smart 130A ESC, supported by a 4WD system with adjustable differentials. The 12mm aluminum shocks and adjustable sway bars ensure stable handling on dirt or gravel, but aggressive jumps may cause chassis flex, risking wear over time. The Falken Wildpeak MT tires offer strong traction, though they wear quickly on asphalt, requiring frequent replacements. The Spektrum AVC system aids control, but high-speed steering can feel twitchy for novices without tuning, and the motor may overheat during prolonged runs.
Design and Features
The Brenthel-inspired body, paired with licensed Method Wheels, delivers scale realism, enhanced by a front LED light bar for nighttime runs. The 4mm aluminum chassis and shock towers withstand heavy impacts, but the polycarbonate body is prone to scratches and cracking during crashes. The absence of a battery and charger adds setup costs, and the stock servo may struggle with precise steering under heavy loads. Adjustable turnbuckles and a center differential allow tuning, though stock settings may feel stiff for technical tracks. Waterproof electronics support wet conditions, per the manual’s standards.,
Ease of Use and Maintenance
The Spektrum DX2E Active transmitter with AVC provides precise control and beginner-friendly steering priority, though its small grip may feel cramped for some. The truck requires a 2S or 3S LiPo battery and charger, with runtimes of 15–30 minutes and charging times of 60–90 minutes. Maintenance is simplified with a metric hardware package, but small screws strip easily, and debris can clog differentials without regular cleaning. The bottom-loading battery compartment eases swaps, but securing it properly can be tricky for beginners.,
Special Notes: This is a Ready to Run model, fully assembled with a Brenthel-inspired body, Spektrum electronics, and four AA transmitter batteries included. Requires a 2S or 3S LiPo battery and charger (not included). Suitable for beginners with AVC, while advanced users can tune differentials or disable AVC for racing.
