Combatpigg: It's silly to draw comparisons between this stuff and full scale flight.
Not at all, both relate to each other. I've been flying RC since '68 (that plane had no ailerons, so rudder was mandatory!), and full-scale instructor since '80 with over 15K hours. Like Hossfly and others have pointed out, those who use rudder minimally are drivers, not pilots.
The reason rudder use is minimal in many modern aircraft (full-size and models) is because many of the bad habits have been engineered out. There is less adverse yaw because the ailerons have higher aspect ratio (narrower chord), and differential is sometimes built in. Look at a 172 vs. a Cub as an example: The 172, being a newer design, has long, thin ailerons with some built-in differential, and produces less adverse yaw. The older Cub has wide, 'barn-door' ailerons with little differential and lots of adverse yaw which needs lots of rudder to coordinate the turn. The 172 still needs rudder to coordinate the turn, just less of it.
We have a chap in our club who has a 1/4-scale Cub. He's had several near-crashes on takeoff, once wound up in the pits narrowly missing two planes, because he's not proficient on rudder. Rudder use is important !
I don't believe you're a troll, but I would encourage you to join a club. It's not wise to fly alone unless it's a Vapor or other tiny aircraft, and the camaraderie is really great. My best buddies are RCers!
