HCT Front Splitter YR Mounting Tubes HCT Rear Diffuser YR Mounting Tubes For even more savings, you can bump up to the full HCT Pro Kit bundle that includes a lot more detailed body parts, body magnet system, and the interior lighted dashboard system! Tips: Some parts may still have some support tree remnants. Using needle nose pliers can pluck those stray strands off the main part. You can also sand down the parts to make them smooth, but be aware that it may lighten or dull the sanded area as compared to the rest of the part if you don't plan on painting them (I didn't paint any of the black parts and kept them bare). If a bolt needs to get through a stubborn hole, a hole reamer or even a simple hex driver may be all that's needed to make the hole larger for the bolt. Some of the large flat surfaces with speckled/rough texture may have residual hot bed adhesion glue residue still on them. If you want to remove that slightly sticky surface, simply clean it with warm water and a micro dot of dish soap (and a soft green Brillo pad can be used to help get the residue off faster). Installations: Please go to each parts' product page to access installation instructions for each part. These instructions are still in development, so please check back for updated instructions. Tech note: Each red LED is 2 volts, 20mA, Anode (+) = longer stem, Cathode (-) = shorter stem. Attention: Please be advised that the HCT aero parts (splitter, wing, diffuser, side skirts) are more for aesthetics than that of actual performance gains. While they might introduce some small amount of aerodynamic gains, it's unlikely that it would be of significant measure in a race situation. Also be cautious that because these aero parts are somewhat extrusive from the car's body, that it introduces added risk of breakage if it collides with another object or if the car flips over. Like with any RC car, please drive carefully!
