Are there any electrical engineers that would design a circuit like this without proper component protection? I hope FIRST will have a lot of replacement units at the Regionals and Championships. You're depending on both motors to split the 5 amps. what happens if one motor quits during a climb, and the other takes the full load?
This is exactly why you DON'T fuse the motors individually, by using a common fuse they both quit at the same time.
