CBK: Thanks for the pictures. Illustrates why it is necessary for careful masking of the cowl. None of the "squares" is the same size and shape. A way needs to be found to taper each of the checkers from front to back and side to side. [Answering an earlier post--no can't scan the article because I don't have the machinery to do so.] Some magazines have a service where they will photocopy articles, I know that R/C Report does. Email MAN and see if they have a similiar service. Their site is: www.modelairplanenews.com. There is usually a "contact us" section. Regards.
