a couple of days ago I had my Tiger 2 out for several great flights and real nice landings. When I was taking off the wing I discovered that one of the wing bolt down blocks had come completely off and the other was really loose. !!! I guess I was ready for a little good luck. Anyways I figure that the tightening up of the bolts just pulled the blocks loose. I've tired to rem,dy this by fixing in a balsa wedge to elimate the space between the wing surface and the blocks. If you're flying a T2 you might want to check these blocks, I know I will be keeping an eye on them. FWIW. : : : :surprised
