I did the 120 several years ago. About the most layed-back fun to fly plane I have had. Will fly amazingly tight manuevers for such a large aircraft. I flew it for quite a while with an old Fox .74, then installed a OS 1.20 4 stroke. It was a fun plane, until the crystal fell out of the receiver in a very low altitude (less than 3') high banked turn. Debris field must have been a 100 yards long. There was a lot of balsa in that plane.[X(]
