This is Jon. Who's Nathan?

Gary, Your Edge didn't have 1/4x20 wing bolts listed? This is not your nylon bolt mod wing mod because it's not shown anywhere else on the instructions.

They show one side of the center wing joiner epoxied and the other side bolted. The instructs don't say what bolts to use. They do say to drill the holes in the joiners out to 1/4", so I assume that's where the 1/4x20 bolts go, because it's the only place 1/4 dia. holes are discussed.

No wing nuts supplied or listed.

It's not worth calling them for a piece of 1/4" dowel and a couple of nylon bolts. I can just go to local hardware store and get fixed up.

Got the engine mount installed for test fitting. Put 1 #6 flat washer behind the mount on the left side bolts. My calculations said this will give about 1.5 deg. of right thrust.
