Interesting dilema.

Since the vxl motors are something like M can, and 2 of those can achieve 60mph on 2x 3s lipo @ 3500kv, then a pair of S cans on 2x2s each should do 40mph easily enough @ 4400kv. Like you said, a single L can is enough power for you, so a pair of S cans should be about equal in that respect- just added cool factor from the twin BL layout.

If you wanted to go for higher speeds, L cans would be better ofcourse...
