Hi!
You can ofcourse use a any prop, including a 10x6 on a .45 engine. On a Q-500 type of plane with a span of 130cm a 10x6 is better but on a 140cm span Cheeroke a 11x6 is the prefered size.

Hi!
Solartex or Oratex and automotive 2-part acryllic paint is what I recommends if you want a car like surface on open structures.

Hi!
The best way to "Painting" a plane is using 2-part automotive acrylic paints. The only "problem" with those is that you have to spray it on and that they are expensive.

Hi!
Did the engine not have a carb? I assume the carb neck diameter is 13mm, so most 10-15cc engine carbs will fit. A Perry carb is not that good compared to modern carbs (30-40 year designs).
