74 is the second top roller collector I've seen with those side flaps mounted to their intake arm.
Pro-tip ! We have found in testing that side flaps significantly help with inbounding for top rollers. We have tested them on our practice robot and plan to add them for Lone Star Regional.
We also found that a hinged ball flap in the front to settle the ball also really improves shooting consistency.
I will put a few pictures on our
DiscoBots thread.
