Pretty much the way that Al did! If you are going to kit bash a Twister or something like that, you don't even need the Mustunt full size plan, just the magazine page to duplicate the construction. The biggest draw back in my opinion to this type of fuselage is the extra weight in the nose that all of the balsa block needed to fill out the nose adds, so be careful in that respect. Keep it to a minimum. It could probably be done with heavy formers and molded sheet.
HAPPY 4TH OF JULY!!!
