This is an excellent product for the Tamiya TT02. This motor mount allows the user greater flexibility when adjusting the mesh between the pinion and spur gear over the stock motor mount. The stock motor mount has fixed holes and is made of plastic, which limits the number of pinions which can be used. This Yeah Racing motor mount also acts as a heat sink due to it being made out of aluminum. Again, this is an excellent product. I strongly recommend buying it if you have a TT02 and I really wish they would have made one like this for the TT01. I give this a score of 5/5. It's great!
