this thread is going to have answers coming or from many to really get down to the weeds.

G-2 helped me learn to fly rc planes.
i would say compared to cars its night and day and a lot more fun.
cars can't do loops and stunts like the more advance planes will do.
the sig lt-40 arf is an outstanding training plane.
join a rc club to get your foot in the door with planes and training along with g-2 if you have a computer and dont mind spending some $$$
this hobby can get you into it very cheap but the $$ start adding up once you get hooked or wreak a lot either way it happens.
if $ is to be saved u have to search for deals like this site offers or hobby shops on used equip.
i hope i have enlighten u some.....
