I am currently getting around 2-3 amps from my slant core 500w PMA in 8-10 mph winds. I am using the 5 Turbo Torque blades. I feel the amps are low and would like to up the Speed of the PMA with the same wind speed. Has anyone else done this? What can i look out for or will it even work? I was thinking about a 2 to 1 ratio. I understand that there would be the drag of 2 more bearings plus a belt to drive. Any Input would help. Thanks.
