damn, nice car, those nitro cars are FAST. a friend of mine has been trying to get me into it, he's got a totally tricked out from the bottom up electric tc3. i've been thinking about getting one, just haven't had time for the sport.
i assume the nitro rs4 is factory shaft-driven, unlike its electric brother? that was my main incentive for going to the tc3.
that is a nice radio, i've only seen a coupe people running it. they are pretty expensive
another friend has been trying to get me into planes as well... i'm not sure what to do! lol
but i do have an old kyosho icarus, if you know what that is. it's pretty much beat to death tho, not really track worthy any more
