The nitroplanes Cessna is a very nice flyer and probably would make a good 4ch step up plane for you. I have one and am generally pleased with it. It will require a little more speed on landing than most trainers and does best with a little power all the way to the ground. Does not fly very fast but is very stable and controllable. It easily does loops, rolls and inverted flight. The supplied 1800mah battery is a little small and provides barely 10 min flights - it really should come with at least a 2200. There's plenty of room in the compartment for a larger battery. The nose wheel landing gear is a little flimsy and easily bent but not hard to bend back.
