When I was building my F-86 Jeff would answer my easy questions but would ignore any thing that was out of the norm. Like the plate that holds the elevator bell crank on the left side was glued in wrong, I was ignored when I asked about it. Like the rudder hinge holes drilled wrong (didn’t line up and no hard points). Ignored. That is just a few of the e-mails that got no response. So I have first hand experience dealing with Jeff. I must say, he did send me a new air cylinder that was leaking, after many unanswered e-mails, I finely got a hold of him on the phone, he sent one right out. George
