The nose looks OK now. I have to repaint in glossy black all the windows. I've put miliput in the interior; that will give some weight and more than that, that will avoid the fact that in the building process some windows to fall out of their emplacement.
For the fuel tanks, I completed the putty with cyano at some locations. Sanding done. But the attachment system to the wing don't fit; I will have to use evergereen and probably miliput too...
I've also looked how the resin "BA" nose would fit: poorly, really poorly... It is a little bit too big...
Actually I'm a little bit deceived by the kit...
