Default HVP Catalina engine setup?
I'm starting to build HVP-modells Catalina PBY-6A seaplane.

I am planning to use 2x Graupner Speed 480 motors and 3S LiPo batteries, here are my questions:

1. What would be the correct size for 3 blade propeller ?" x ?" (6" seems to be the maximum)?

2. How much mAh should there be in the LiPos to achieve appr. 15-20 min flight time?
