Actually.. I have 2 other Nitro RCs... This will be my first kit and my Buggy. Higher $$ motors, are really no prob.. I don't know if I'd like to run the OS RG in the 8ight.. It doesn't seem right.. It's like a hobo in a Limo.. doesn't really mix. But ehh... yeah.. I dunno. Why would the OS RG be a better starter engine?
