Materials and processes are different, unless you worked with some styrene RC stuff. And the detail, while not different in kind, is different in quantity. There is an old saying in military, "sometimes quantity has a quality all of its own." Practicing a new skill is never a bad idea before going operational :-)
Advice from someone who has lived in both worlds. BTW, gave up on RC when I moved to a windier, snowier, and colder environment :-(
