Looks like a hodge podge of parts. The cowling, wheel pants, struts, flaperons and gear legs are off a plane that that has seen some action. I would guess that it was wrecked and someone found another fuse to use to put the plane back together.
I flew a buddies that had the wing extension and the flaperons moved out to the end. He just drilled out the rivets that held the control arm on and slipped a piece of tube over the tubing and inserted an extension inside it and riveted it all back together. The next size larger tubing in .058 wall thickness will fit nicely over the tube.
Jim, That is how the Montana Coyote is. I have not yet pulled mine apart but they are really stiff right now on the basket case I have. I will have to get them apart and clean them up and see if I can get them working freely again. I will post pics of the system when I get back on the project.
If it is an A model you have a lower gross on it and it would best serve you to keep it LIGHT! I would be more tempted to throw a 503 on it than a yammy if you want to be able to fly with more than half tanks.
