hey guys i am new to NITRO RC'ing. been in the electric scene for a little bit, but now i just started nitro....i am buying a TA NTC3 road car. I have some questions. it will accept a rotary carb, or a slide carb motor. what is the difference??? how they work???? Another thing they told me is that it wont accept a big block. what is a big block? is it relative to car terms??? or is it the higher the number gets, it moves from a small to a big? I just want to start understanding all the engine lingo used in here. Thanks for looking and for any help you can give me

Mike
