RE: Primer question
I like to finish the model all the way up front. I feel it is easier to paint control surfaces before they are attached, and not have to worry about getting paint on anything that should not be painted. Flew our BobCat in primer for about 2 months, then had to remove everything to paint it, and then put it all back in again. Turned out okay, just not sure I would want to do it again.
