fuel tank baffles

[chewton]

seems the holes to let fule thru baffle to pickup look real small? and why no trap door to let it in then keep it there? thoughts anybody.

My thoughts are... that they are sized very specifically for a flow rate that matches the requirements of the Rotax 912ULS engine at takeoff power.
There are engineering reasons that you are directed to seal certain portions of the baffles, and then be certain that you have not sealed others.

Pretty large openings

They are big enough to feed any RV engine available. They would flow lots of gals per hour. I'd say they are to help ensure enough fuel is available during prolonged climbing.
