I fly a Maule MX-7-180 TW in and out of unprepared fields (grass, dirt and sand) and 3 point it every time, the primary reason being when I bought the plane from the factory I took a flight with Mr Ray Maule and he told me to always 3 point it, now i am not sure if that was his best advice in regards to the planes performance or a reflection of my capabilities, but I have followed his advice and it lands like a dream and is very forgiving regardless of how rough the field is.
