Re: Burning the FP's
We tried two stock FP Gearboxes with an additional 6:1 reduction (180*6= 1080 total reduction) and it powered our 7 lb, ~4.5 ft arm but drew 30 Amps each when 13 lbs were loaded at the end of the arm. See attached pics #297 & #303.
Not a good scenario for those FP's - design it so they don't have to draw more than 15-20 Amps at full load, otherwise they just might not last. We made a new transmission that has 260:1 reduction (see attached pic #311) and then the additional 6:1 for a total of over 1500:1 reduction. Hopefully this will keep the motors in tip top shape and we still get a couple ft/sec at the end of the arm.
