The Traxxas Slayer Pro 4x4 is a great Short Course Truck if you are into Nitro powered trucks. The Slayer come with the Traxxas 3.3 nitro racing engine, a 2-speed transmission, a limited slip differentials, wide-track suspension arms, Waterproof servos, and semi-metallic brake pads, and a blue anodized 3mm thick chassis. The Slayer comes with a few features, this includes a 2.4GHz TQi Transmitter, a Fuel bottle, the Traxxas EZ-Start, a spare Glow plug, and spare Air filter. I have great joy when I run this truck. The noise, the smell, the speed, the dust flying, they are great. My only recommendation is that you replace the steering servo with either a metal gear servo or stronger servo because I broke 6 teeth in the steering servo within 2 days. To Conclude, this is a fast, fun, strong short course truck. I love this truck and would recommend it to anybody who asks for a recommendation.
