SPRING AIR....

Bill Watton at Spring Air personally flys the retract ready Bobcat 50 and he went with the 702 system along with #152 struts for the main.
As far as the nose gear I ordered the Robart part #656 Fork Strut to fit on the Spring Air 702. Correct me if I'm wrong Tumbler....

Because I take off and land on semi rough grass still debating with myself if it was a good idea or not. I've now cemented the base of the retracts
pretty good after maiden. I'll see where I'm at with her after 2nd day of flying mid-week.
