As the kit says Hoerner wing tips were an option on the cessna 182, so the full scale version could be found without them on it! The Hoerner tips were added to help add alittle to some acrobatics. The plane will fly with a reg wingtip quite well! If you build this kit with the flaps, then you can make the tips. They are easy to make! I'm building theplane now and with all the bells and whistles I'm finding that a hatch door for all the switches and charging plugs is a necessity.
