I picked this up on E-bay last year and spent about 6 months off and on working on it, finally finishing it up last weekend. It was a very frustrating buld and almosted ended up in the trash a couple of times. The fit for all of the interiror and the wings were great... the underside was not.
I added so much weight that I was afraid that the nose gear would not be able to support it. The gear was strudier than I thought and it is still a tail sitter.

The decals were also a source of frustration as they would not come off the backing paper. I had to work a paint brush under every decal to get them to come loose although they did adhere well when I got them on.
I used pre-cut masks and added masking tape seat belts.
She won't win any contests but I am happy with overall result. Glad I stuck to it.
