Interested In the Duotone 3 blade propeller, anyone have any experience / feedback on how it performs? And also know the hole centres for motor mount?
Interesting R&D with Yamaha. Maybe someone here will be able to scan it one day

The main thing to crack for super high motor is how quick it can remove the bubbles after breach and how it handles having the prop semi-submerged.
It looks nice, I like the shape
