Ran the truck in its first race this weekend and was very happy to take first place. The truck has a great ability to turn in both on and off power, unlike the losi and OFNA trucks. I was also the only one using a 540 sized motor in the whole class. A 6.5 Ballistic with 12* of timing in the motor and 30* more in the spedo using full time sensored mode gave me the same top end as my two closest competors that wrer running 4.5 550's. It was also a power hugry setup that required the use of a 5300mah 65c Thunder Power battery for a 8min main. Only complaint I had was the preassembled shocks let the screw for the piston back off and fall apart.
