Shaun,
I sanded the balsa wing doublers down to the plywood fuse sides at the same angle the the top of the wing hits it. If you are missing the wing hold down plate just cut one from a piece of 1/4 inch thick plywood. I will take a picture of mine tonite and post it tomorrow morning for you. I will measure the length of the plate for you also. The hold down plate is secured by the precut balsa triangle pieces. I will also send a picture of the flap servo and linkage.
All I need now to finish mine is some free time to work on it!
