Brad,
You had to ask how the wing fits the fuse: well it doesn't
=======
wings (cont)
I have an older FG fuse that I probably will use versus building a wood one.
I put the wing in the fuse saddle and the wing is about an 1/8" too long.
Initially, I thought I could just cut the TE as that would be the easiest way: except it would involve cutting part of the flaps and that would look strange in the down position.
Initially, cutting the front seemed like a lot of work but it turned out to be easier and faster than I thought.
Again, I just used the heat gun to soften the epoxy and the front ply plate came right off. I then used some diamond impregnated cut off disks that I bought a few years ago at a flea market (never have too many tools, even if you don't need them right away) and trimmed the front about an 3/16" back. Made a new ply front plate and epoxied it back on.
Now, the wing fits the fuse: and the wing filet: just about perfect.
Alternate flap hinges:
Besides the surface hinges that I made for the P-51, an alternative is what I used on the B-26 that has less hinge showing but the LE of the flap has to have slots cut into it.
Flaps:
I made up the control rods and binded the transmitter to the receiver so I can get accurate servo/flap alignment. I like to make all fine adjustments with the transmitter while it's easy to access all the parts and makes assembly after painting, much easier.
Initially, I was going to just epoxy the servo tray to the top sheeting but I'll epoxy some 1/4" square spruce between two ribs and then screw the tray to the spruce as that will give me flexibility to fine tune the tray, if need be.
