I know, I know, it's technically an MPR, not an HPR. HOWEVER, as I'm building it, I should be able to fly it with H motors, at the very least, so nyah!
Starting out with the fin vac bagging and the airframe glass wrap:
Used a Zwilling vacuum sealer bag (9"x12" size) and Duco Plastic Cement to put them together. The vac bagging was to clamp the pieces while the cement was setting.
Approximately 4oz. of U.S. Composites' thin epoxy with the Medium hardener @3:1 mix ratio. Soller Composites' Light Fiberglass Sleeve (white) and their heat-shrink wrap. The blue shop towel is to soak up excess resin from the one small pinhole that developed when applying the heat gun to the wrap. I cleaned up the spilt epoxy using 99% Isopropyl Alcohol. Later this afternoon, I'll peel the wrap off and cut out the fin slots and trim the ends. I used a 2" sponge brush to apply the epoxy over the 'glass.
