Hi Dave,
Yes, original color scheme. Maybe a shade lighter on the blue.

This method of attaching the ply plate has worked for me with all my .60 PP's 30 yrs ago, and this is only a .45 ship. Those ships had thousands of flights on them, never a hint of failure. I'm not worried at all. The key is to get a good glue joint with the tri-stock onto something solid. My .60 ships had 1/32 ply doublers that the ply was glued to.

If you want to play with the math, the .60 ships were 7.5 lbs of which 1.5+ was the wing, In a tight outside loop or outside square corner, perhaps pulling 10 g's, That's only 60 pounds trying to separate the wing from the body. You have dowels in front, and the screws in back. Figure half and half forces, a good glue joint on each side for the screws is only 15 pounds, minus the glue across the bulkhead, and the structure is much much stronger than that. Double that to 20 G's, and it's still only 30 pounds on the side joint.

However, I appreciate your concern, thanks for bringing it up. Did you ever have a wing bolt plate failure yourself? It's discussions like this that make forums so useful. We all learn from each other. I'm very glad you brought this up.
