RE: 60 size ARF
My vote... Get an Ultra Stick and fly the daylights out of it. Great second plane, easy to fly, and will do most stunts as your flying progresses.
My personalidea for a 60 sized plane would be an Ultra Stick 40 with a 60 on it. That is still my every day flyer. I built mine with the quad flap option, which is hugely entertaining.
