I got my CX 3 days ago and read the book.It needed the linkage and the pot mix adjusted so I didn't max out the trim.With only 2 charges,I was abale to trim it properly.I never flew a rc heli, but I flew heli's on battlefield 2 so much that it was very easy to learn.Its been 5 flights and I can do all the tricks they do in the training video.I am hooked on heli's for sure.All the posts are great and the members here are cool.I can't wait to get a nice outdoor heli too.
