Now to the building of the Engel Horten: At first I detached the canopy along the split
line. For this work I used a flexible steel ruler and a sharp knife. Be careful with the
knife. Shit happens...
Before start of building I've gotten a practice
report from Ralf Fuchs(in German). So the next step was to reinforce the landing skid.
I cutted out the fiberglass cloth, which is in the front of the inner wing. A trimmed
balsa part was glued with thickened epoxy resin into the opened skid. The front of the
landing skid was also glued with strong thickened epoxy resin. Later a launching hook for
the rubber band should be implemented. After drying you have a very stable landing skid,
which should be strong enough for harder landings.
The next step in the building instruction describes the reinforcement of the blue styro
foam in the middle of the wing. You should use 163 gramm fiberglass strips. I decided to
use carbon fiber strips, which should overlap 100 mm in the middle section. The whole
procedure can be viewed on the images.
