Just got a revo, its gonna be brushess!...

[RC-Monster Mike]

I will have Neu and Feigao 540c specific rear supports(and a slightly higher front mount) for these kits by the end of the weekend. I modified the design to raise the motor mount holes .1" to allow use of most motors typically used(Feigao 540c, Neu). The initial mount was optimized for smooth can motors.
The whole idea with this mount is that is a direct bolt on and allows use of the nitro final adjustments. I could easliy make a lower cg mount to bolt right to the chassis, but thought the nitro adjustment was a nice feature to incorporate(one or two screws that are easily accessed vs. adjusting the mount and rear support each time). With the motor any lower, it becomes a real PITA to make adjustments as well, as accessing the screws(lower screw in particular) would almost REQUIRE removing the radio tray.
The front mount and rear support are around 5mm thick - with support at the rear, I felt a thicker mount was unnecessary and would only add weight and potential pinion/set screw issues. :)
