RC8B4.1 Team Kit
The build begins by using the base kit from Team Associated. The newly released kit comes with many of the options we used to add to the previous RC8B4 Team Kit. Including: 17mm outdrives, Universals and the correct Shock Springs.
MXS Competition Nitro Engine and 2141 Exhaust System Combo
This is the 3 port .21 Off-Road Ultimate MXS Ceramic Competition Engine. Like its predecessor M3X, the MXS is made by the prestigious Japanese O.S. Engines brand and it's based on their square stroke Speed B21 Ty Tessmann II edition engine but has some modifications on the crankshaft as well as on the back plate to improve performance. This engine has more power and returns to idle way better.
With this engine you will have a really good power band with a ton of usable power. It has a smooth bottom end which worked well on the bumpy track and then has a lot of mid-range pop and feel to it. It is one of the best idling engines on the market.
