Revo 3.3 Slayer Pro Forward only gear conversion and notes about Big Block Installation X5360

The Traxxas Big Block Kit (X5360) is made to fit Thunder Tiger Magnum Pro .21 O.S. Style big block such as the RG and RZ and Associated Pro .21. Skip to https://www.seevid.ir/fa/w/Zq5FdwMybVM for the forward only conversion. I complete the forward only conversion but not the big block conversion. But I do explain what is needed for the big block conversion. I just do not have the correct size engine. Some SH engines will fit. I apologize for saying .28... it should be .21. The SH .28 is too big.
