Phil, Your math and reasoning are correct, but instead of using the numbers for nominal current draw, I would go for something between peak and stall. Your motors are going to consume a lot of power doing things like skid turns. I would select fuses with amperage ratings maybe 10% below stall (I just pulled this number out of thin air, I'm sure more people will chime in) For 12/24VDC, I can't think of any reason at the moment why the voltage rating would be a primary concern. Also, I would think that a slow blow fuse would be more appropriate -- You are currently subscribed to the "R/C Tank Combat" group.
