5280 no load rpm ---> 251 rpm with the reduction ,. this still seems kind of fast with the standard kit size wheels, are you using other sprockets not provided in the kit ?

251 rpm is 4.2 revs per second. With a 6" dia. wheel the circumference is 18.8 inches, giving a theoretical top speed of 6.6 feet per second. (Or 2m/s aka 7.2km/h) With smaller wheels, you'll be slower.
Depending on your team's strategy you might like the pushing power that offers or you might want to move faster. I'm looking at the opportunity for direct drive from the tranny output shaft and a bit more speed.
Someone earlier posted about how best to drive a 6wd chassis with four gearboxes. I'd say direct drive to two axles and chains or belts linking all three axles.
