F18 Build - Part 5

I decided to add the aileron stock before doing the bottom spar tonight. The only decent aileron stock I could lay my hands on was 8x35mm stock from Mad Models. Probably a bit wide but I will be cutting the ailerons about 25-27mm wide leaving a sub trailing edge of 5-8mm. After measuring it off the wing, a sharp exacto blade takes care of the rest.

The aileron stock was too thick by about 2mm. Nothing a bit of creative shaping can't solve.

So out comes the hand planer. The masking tape is there so I don't accidently start ripping chunks out the foam. One slip and you have to start some unsightly patch work.

After removing the bulk of the excess balsa with the planer, the finer shaping is done with a big sanding block to ensure true flat surfaces. A quick eyeball on the end result and I'm happy.

I used polyurethane wood glue to stick the balsa to the foam. Masking tape held everything in place and while that was drying I could enjoy my dinner.

Looking good so far. The bottom carbon spars and balsa cap came next and I won't bore our blog readers with more pictures of that. Unfortunately I will now be going away for the weekend and will only be able to continue work on the project Monday evening, when I intend stripping off the foam leading edge and replacing it with a balse one, so expect an update by Tuesday.

Cheers, and enjoy the weekend!
