Used PMC 780 and a 3D print as a plug after scanning plenum and inlet rings to fabricate the inlets.
Positives - fit is great. And it is fun playing with new materials such as the liquid polyurethane!
Negatives - I tried to lay up some fiberglass on top of the polyurethane and wet it out without putting it between plastic film and forcing the PMC into the fiber. Doesn't work. The inlet position is not ideal, but I'll experiment with moving the rings vertically to provide better airflow once flying. Would like a baseline before making changes.
Results - an enjoyable project and fairly simple to do. Remake with saturated fiberglass, with a small reinforcement of a single layer of fiberglass at the sharp corners. Might try using carbon fiber on the next attempt.
