I can see where the counter sinking the top deck or brace would help with the stiffness and help prevent movement in a hard crash, but I would rather have a button head there. Reason being, during the prototype work on the BMI 1/12 car Jason from BMI noticed there was a variation in the countersinks, heads, and concentricity of the 4-40 flat heads. We would put the main chassis brace on and the chassis and it would twist and be tweeked. There needs to be some room for the inconsistancy of the screws, standoffs and locations on the graphite. If everything in the world was 100% accurate It would be fine, but it's not, so room for error is needed. Maybe because of the smaller size standoffs and thinner graphite pieces for 1/12 it's more critical. But we did have a lot of problem trying to use flat heads there.
