Thanks everyone for your kind words. After that build I think I may need therapy. Therapy being more building !! Am I right ?
Anyway, onward and upward with the -C "Hell-er-Bust". I managed to get the flaps cut from the wings because I want to drop them. But I'm not going as far as I did with "Doll". I used a scribing tool to cut them off with and I got nice clean edges.
Once that is done I use a rat tail file and channel out the inner edges of the flaps to make room and shape for the round stock I put in to give the flaps its upper curve as it enters the wings. Seen here.
I then take my time, and it does take a bit, to gently remove material along the upper wing edge on the inside to make them with as thin as possible to achieve a really nice tight fit for the round stock when they are placed on the wing.
This is the area here where I am pointing. The lower edge also needs some work but not as much. Just enough, along with the flap, to make them fit just right.
Once all the fine fitting is done you will have a nice fit to the wing. It is important to remember that there is a transition from the wing to the flaps where the flaps pull away from the wing, or roll down exposing the curve that is normally hidden in the wing and that the curve is not flush with the wing nor the flap, but slightly lower by the thickness of the surface skin. If that makes sense. So, if you position the round stock correctly it will not be totally flush with the flap or wing when installed, giving it the correct appearance.
The underside of the wing will also need some attention to get all these parts to align correctly and not look, out of place. It is hard to see in the photo but the flap just slips inside the wing, and we have a nice tight fit. Even if I am holding it with one finger.
Now as you can see in the earlier shots of just the new flaps, the ends are open. I will cover them with sheet stock and trim to fit and finalize the fit to the wing and wing root completing this part. I will be using aluminum foil tape on the round stock to give it the unpainted look I want for that part being exposed. Then I will paint the flaps and the plane separately and assemble them during final assy. I learned from the last one that it is too hard to paint around them without getting pebbling.
