Very nice kit to assemble. Super easy to read and follow instructions. Parts are made of high quality plastic materials and the body is very nicely molded. If you are building this kit I reccomend you also purchase ball bearings for it. It will increase your speed, run times and longevity of moving parts. The TT02 is a great chassis to bash and have fun with young or old. It's sturdy and simple design makes modification and maintenance a breeze. Can also fit a wide variety of batteries as the compartment is quite large. I have 3 of these kits, and I can safely say that it is one of Tamiya's most reliable kits ever made since the TA02. There's is lots of tuning for a simple kit and plenty of hopups to be had. The torque tuned motor is also a nice addition to this kit.
