Hello to all,
(Jan, I am awaiting factory parts to complete my Skymaster 1/5 F86 any build tips would be appreciated.)

I bought an Aurora, huge, and after I received I noticed how stiff the hinges were. I wish I had put a pull scale on them but had to be may pounds of force and could not achieve anywhere near recommended max deflection. It had been repainted and turns out to be very thick paint and many other problems. What would have been a square skin cut over the hinge was reduced to just a tiny depression line in the paint.

I drew a deep breath and used the point of a dull pocket knife and began to scrape out paint. By the time the cut out skin began to show some definition the hinges began to move far more normally. Since flaps and one elevator already have hinge point repair I was willing to risk cutting through. Happily it did not and ailerons and rudder saved.
.
Anyway if paint or repaint I strongly recommend finding a way to protect hinge skin cutout.

Very shocking how strong the paint in the hinge cutout was and even stopped the movement away from the paint side. I thought that would have just split the paint open but probably urethane paint
