Hello Przemol. Thank you for the kind comment.
Red, yellow, and white are notorious for lack of opacity. I use the lack of opacity to an advantage. First I primer everything with white primer (Tamiya spray), then use a pencil to draw in the separation lines around the moving flight surfaces. Then I paint the yellow color, also Tamiya - chrome yellow for this one. I use the same procedure for white sailplanes. This emphasizes the lines without making them too harsh.
The resin in these Spin kits is the tan colored type used several years ago. Good casting, but not exceptional detail. At least there are very few bubbles in the Spin resin kits.
