The ONLY 2 defect I found so far with this kit (not much really if you think about it).

1. The glue joint came loose. No biggie. A little 15 min epoxy, and it's fixed. I'll probably add a couple of small triangular balsa to hold it togethter better.

2. Poor design I guess. You can see the bend in the bottom part of that former. A simple cross grain ply will fix that (balsa will probably work too).
