After having a Skytiger (Tiger II father) for many years and tearing off the wing due to tall grass, cowpies, and toad stools, I knew that 4-40 bolt/lite ply set up on my Tiger II Arf was not going to make it the first time at the grass field. You need nylon so that the bolts break away without tearing up the wing.

I cut my wing mount out completely. Then I took two 1"x1"x1/2" spruce blocks and screwed then into the side of the fuselage. Tap out holes for Nylon wing bolts, then you have it made.

I have no idea why these ARF kits design such dumpy wing mount bolt mounts. I just finished a Kaos with the same guaranteed to fail setup.
