Hey @s.moriwaki I received my ulton sputnik today. You weren't kidding, that drip tip was hell to dislodge, and the o-ring is shredding like crazy when I adjust the JFC.

Have you found that your airflow increase when screwing the RTA onto a mod? It seems like the airdisk is shifting when the 510 pin's pressed down. I swapped out the orings on the airdisks to make them more snug, but it's only improved the issue slightly.
