Updates...

I am at work tonight so I will not have pictures to go with my text, I have the pictures and will post them soon...

Worked continued and I am back to solving the original problem of mounting the wing. As I said previously, I have added two doublers to the bulkhead just forward of the wing opening, this is the bulkhead that carries the front of the wing. I have now added a 1/4 inch ply doubler to the inside of the wing where the mounting pins will hold the wing to the fuse. I feel that this will be more than enough to carry the wing loads in flight.

Next I made the wing hold down dowels. These are made from hollow carbon tubing with a center core of hardwood dowel. the outside diameter of the carbon dowel assembly is 1/2 inch and there will be two of them holding the wing in place. I seriously doubt that these will fail under any conditions.

Once I have the front of the wing pinned in place it will be time to start work on the rear hold down. I plan to use the same 4mm size bolts I have in my Flash so my field equipment requirements stay at a minimum.

On a side thought, I have read and read the Modelbau instructions on wing mounting and I still have no idea what they are wanting you to do for the front hold downs....no matter as I have moved past this part anyway.
