After finishing some details on the upper fuse half, it’s time to turn the fuse over. I’ve made a ‘stand’ from thick insulation styrofoam board, which works pretty well. The structure builds up quick, as usual:

Here you can see the stand and the fuselage’s position a bit better. I traced the intersections of F1 and F6 on the plans, cut them with a fret saw out of styrofoam and covered the upper faces with masking tape for further protection:

Meanwhile, I’ve started blending the underside of the stabilizer with the fuse, initially with a bead of epoxy, to finish it off with balsa filler:

I also made the underside of the battery hatch. Still not sure how it’ll be fitted, but this makes it stronger and also adds the capability of using magnets later on:
