This title covers the upgrade and maintenance tips & techniques for a broad range of Tamiya offroad EP models. Many current models and rerelease models are covered. (we are NOT associated with Tamiya). What makes us unique is that, rather than just telling you what upgrade kits to buy, we tell you what quick fixes and workarounds can be applied to solve problems when you don't have all the parts handy. We even go one step further by telling you what preventive measures can be taken to avoid problems.
