I'm thinking about offering my 1971 150 Airobat for straight trade for a mid time 170 or 170A. Maybe I am crazy, but a trade would seem easier than selling my plane, searching, and maybe financing a new plane, which would require expensive insurance. This plane has been a great bird for knocking around Alaska for many years but it just doesn't fit my needs anymore. It has less than 100 hours SMOH. It would be a great trainer for PPL, IFR or basic airobatics.
