Interesting, I knew an M-08 wasn't far behind when the M-07 was released. I'd love to see some pictures. I don't race, but do enjoy my M chassis cars. Don't know if I need or want an M-08. Being mid motor, handling should improve over the M-06, if you don't decide to overpower it.
My M-05 spends it's time in the dirt with 1/16 Slash tires. My M-06 is a handful of brushless mayhem and on TC size tires holds a wheelie.
