Round and round...

Kept working on the ailerons, not without some head-scratching issues..
Rounded tips now, and balance tab too!



i discovered that in top flite GS corsair the balance tabs of ailerons are not intended to be scale; the tip of the balance tab, in fact, in real scale f4u was rounded and the stab, in that point, was "carved" to let the balance tab move freely. not in this kit!  the rounding of the tab is only slightly curved and then it's flat; the building manual is silent about it, but i'll try to do it as scale as possible. so i will glue a flat surface on the stab, just in front of the balance tab ( to fill the gap that in this point is important) and then carve it to make a shape that will "hug" the balance tab. ok, stop writing.










I left behind the stab sanding so now i'm on it. i draw a line in the center to ensure to sand simmetrically.


I used the Graal of sanding, the great planes multi sander, sanding LE or TE made easy.



These are the results, easy task with the Graal!


First half done...


..and that's it!


Next step will be to sand and cut the ailerons' ribs and give them the right profile.

I noticed (sadly too late) that the stabs are not scale too! the entire surface is flat in this kit but in the real plane the two halves were taped, and the tips were significantly thinner than the roots. i would be forced to start all the project over, but now that i started i won't stop. maybe i'll reproject some stabs and ailerons later in the building, in exact scale...maybe...later...
see you!
