You will love the XTM. Have you bought one already?? The MMT is the baddest MT I have driven and owned. They have an almost 17" wheelbase so they are prefect for high speeds. How do you plan on mounting the twin motors?? Their isn't much room around the spur bracing. Will be curious to see how you fit it.
I have not bought it yet. Still saving for all the components. I was thinking about taking out the engine, receiver box, battery box, and brake servo. (It will be relocated), and mount one motor per side of the spur.
