The adjusters were tack glued to the plywood adjuster blocks.. The adjuster just slides into the wing socket through the fuse. Make sure your Wing TE is still on the pointer or mark for the 0.5deg incidence angle. The adjuster installs with the Screw heads pointing up. Make sure the adjuster is vertical. You don’t want the pin moving forward and back at the same time its moving vertically.

CA glue the adjuster-plate assembly into the fuse. Use Medium CA This way you can use a ball driver to make adjustments. Only do this to the rear adjusters. This will allow you to fix a mistake easier than doing all 4 at once. Once we are sure everything is correct and back on the marks you can do the front adjusters.

I remove the wing panels after I have the rear adjuster glued in on both sides. The next step it to install screws to hold the adjusters to the fuse. Using a Pin vice and a small drill bit I drilled from the inside of the fuse through the adjuster holes to the outside of the fuse. It’s a pretty easy task. Next is use a drill and enlarge the hole from the small bit to that which can take a 4-40 bolt. My machinist’s handbook says that drill bit is a #33 0.113” diameter. So its about 1 size smaller than 1/8” drill.


Be careful at the adjusters are only tack glued to the plates. Once you have the holes drilled look at the adjuster’s position in the fuse slot. Is there enough room for adjustment? In the case of the photo below there is plenty of room above the adjuster pin below is only about 1/8”. This is enough room. Our settings above told us that 3/32” is about 1/2 deg. This means that since the adjuster is near the Trailing edge 1/8” vertical movement gives us well over 1 deg total positive if we need it. I know we won’t need it but its there in case we make major changes. If your model doesn’t allow for 1/8” movement in the adjuster pin up and down….after the screw holes are drilled pop the adjuster off the plate and use a dremel to open up the slot in the fuse to get the desired travel of the adjuster if its needed. You also want a little gap on the sides of the pin. It does not need to be much but a small gap on the side of the pin is good. Install the screws and hex nuts for to hold the adjusters in place. I use a small drop of medium CA on the screw to hold the hex nut from backing off the screw under vibration. Don’t get messy with the CA little drop will do the trick. If you choose some Blue lock tite will also work.
