RE: a few novice questions.
I'm just putting together my 4-channel Art-Tech Cessna (same plane the ParkFlyers sells) and I noticed that the wing has almost no dihedral. You won't be able to fly this plane without using the ailerons. I bought this plane last May, when I was just learning to fly with a 2-channel Firebird. I realized that it was too advanced for me at that time, so I set it aside. I've been flying 3-channel planes since last summer, and now I feel that I am finally ready to try 4-channel. A little nervous but excited too. I never could figure out how to do rolls with a 3-channel plane, so I am looking forward to trying them with the Cessna.
