I love the idea of flying RC helicopters. I can do OK with the little toy versions. But as long time readers of this site know, I am no pilot. I have a hobby grade electric RC helicopter but I can't do much more than lift up off the ground and land again -- not always gracefully. But I have a trio of books from Traplet Publications that all focus on RC helicopters. The most important one for me right now, and any beginning or wanna be pilot, is R/C Model Helicopters - A Guide for Beginners by Malcolm Messiter. I'm not one to sit still for long to read a book but this one gets my attention -- in part because it's short, but fairly thorough.
