the dolphin was my first low wing taildragger. nice plane with a good instruction manual. i did have bad wing flutter though it was an easy fix. i had a o.s. 50sx on it and am now breaking in a moki 61 in it. also had a strega with a o.s. 60fx in it. nice handling plane. the only other problem i had with these planes was the weak landing gear. it was bad on both planes.
