First, I assumed a 4.5" tire diameter based on the picture. Then I assumed a WOT loaded voltage of 3.5vC (21V).
21V*2200kV=46200rpm.
46200/8=5775rpm (at wheels).
5775*60=346500rph (revs per hour).
4.5"*3.14159=14.137155" (tire rollout, inches).
14.137155"*346500=4898524.2075inh (inches per hour).
4898524.2075inh/12=408210.350625fth (feet per hour).
408210.350625fth/5280ftm (feet per mile) = (drum roll)
77.31256640625mph.
Did you get all that? Pop-quiz tomorrow......
