So, here is a never-before published building tip for those in the early/middle phase of airframe construction. It applies to both the 320 and IV... You will have to use micro to close out and finish the ends of all control surfaces, as well as the adjacent structure (i.e. wing tip, wing root and horizontal stab). The micro will then have pin holes and you will eventually have to finish it as well before painting. An easy and neat way to do that is as follows: 1) Take a small size of ¼" prepreg and lay the rough side against the surface to be finished. 2) Trace out the approximate outline necessary to cover the surface. Then use a jig saw to cut the prepreg (slightly oversize). 3) Use pliers to grip the smooth side of the prepreg and strip it off (it will have some honeycomb attached). Then, use your dremel sanding disc to sand it off smooth. 4) Hysol the sanded side to the surface to be finished. After the Hysol cures, use sandpaper to trim the excess prepreg so that it matches the surface exactly. That makes the best and easiest closeout ever !! Bill Rumburg N403WR (Sonic Boom)
