As I intend to fit my supermarine, after Doug has finished his magic, into a vintage Aerokits Sea Commander, what prop would be best, if I am using a 12v 7ah sla battery
. I have available 2.5 inch 4 blade brass prop
, 2 inch 3 blade brass, and various plastic 2 or 3 bade, in 30-35-40&45mm. Which would be the correct one to use.
Any thoughts would be much appreciated, cheers Colin.
