OMG. Kevin and I used to sneak that airplane out in Santa Paula back in the 70's. I did many flights in that aircraft with Grace up and down the West coast. I remember landing in Oceanside one day and Grace making me wait on the ramp while she went and did her airshow routine out on the runway. After she returned, I remember the airport manager finding us and reprimanding her. Grace also used to teach aerobatics at Martin Aviation located at Orange County Airport back then as well. I remember that they had a couple Great Lakes and one owner had a 1929 Fleet.
I believe that J3 was upgraded to an 80 horsepower Continental, if I remember correctly.
Those were great days.
Kevin - I sent you an email, but it was returned. Mine is
