It took three of us 5 hours to mount the dang engine. I don't think we could have done it without Cory. The dang dynafocal mount makes it almost impossible. But, in the end everything worked out well and the plane now stand on it's own.
I had to grind down two wrenches to hold the nuts when we torqued the bolts. One I had to grind thinner and another skinnier.
