Sorry, I should have been more descriptive.

The attached image shows what I meant by "the entire wing", which should have read "all the way around". Also shown is the location of the strip of 1" strapping tape on the LE.

I never tried to make an LE "cover" from PETG. Neat idea, but it would be pretty heavy.

I don't build my wings to have a ridgid LE. The LE shown has some give that allows this wing to absorb and disipate impact energy. In short, they bounce off of almost anything they hit. In fact, the only impacts that have penetrated this type of LE are direct engine strikes. I'm not about to waste my time/effort/money trying to engineer an LE that can go through an engine without damage.

Some combat pilots approach this problem by attempting to build an LE that is (supposedly) stronger than anything it might hit. The problem with this theory is that someone always comes up with something that is stronger and the LE eventually fails.

As long as it bounces, it can hit steel and still survive.

HTH,
