I had a hard time to figure what shape of side cover
would provide a good fit so that the weather strip seals against the
fuselage without interfering with the top skin screws. The layout
provided in the XL canopy plans did not fit well enough (a side cover with
a single bend).
Another builder modified the cover and added a small 15 degree angle at
the top and had good result. I tried this and about 15 other shapes
using small pieces of aluminum scrap and finally found something that
works on my own plane. My side covers include three bends. The
lower bend is 20 degrees. 16mm higher is the second bend that is 10
degrees. Another 16mm higher is the third bend made at 14
degrees. The top flange is 8mm and the bottom one is adjusted for
fit (it was made at 24mm and then cut to fit).
Since the canopy fits so well on the front fuselage, I elected not to
install a front flashing.
