Feb 8 2020, a Hangar 9, 30cc Ultra Stick, with a DLE 35ra engine, crashed at our field.

The cause was reported to be due to the vertical stab breaking off of the aircraft because the wood grain was running horizontally. The vertical stab, the fixed part of the rudder, broke in half at the root near the fuselage. For maximum strength, it should be running vertically.

If you have one of these, it would be wise to add the flying wires to the tail to prevent the vertical stab from breaking.

This 'wrong wood grain direction' problem was also seen a few years ago on a P-47 elevator.
