Joe,
Notice on your reference page that most solders are in the 350-400 F melting range. These are measured on just the melting of the solder product under controlled conditions and are usually thought of as absolute minimums. In practice on soldered connections in is necessary to get the connection over 400 degrees in order to form a good bond with all the metals. (i.e. non cold solder joint) Please remember that the current capability of wire is expressed in terms of a fixed length in open air or conduit for a fixed temperature rise at a fixed (constant) current over a fixed length of time. Although I haven't determined the wire gauge yet, a short piece of #16 with good connections at both ends would sink some of the heat generated, raising the allowable current before failure.
Also of note, now that specs are published, the motor is reaching peak efficiency at a 25-35 amp range so I don't think most teams will have much of a problem.
