The Blimp Items do not trigger a yellow quest progress bar in the top right, but they are collecting normally to your account. Plutonium, Propellers, Control Panels, and Frames will add to your total the instant you complete and action and they drop. You can double check that they are dropping correctly by noting your item totals before completing such actions.
Why are my Blimp creation items not collecting properly?
