Scott, thank you. While air driven fans were working well, I didn't feel secure that the system would be durable. The little fans are sitting on needle point in a small pool of graphite and each fan is unique to it's position in the air duct due to different baffles. Seeing how well the toy motor worked in the baby shark, I installed them in the big one. Outwardly looks the same but I feel this system will endure, and is more likely to stay in sync.
