this would be so scary!!!!!!!!!!

If somebody installed a 4.0 motor (which can be bought at rcmod.com) and 1:1 ratio gears, then the car would go at a speed of an ACTUAL 70 MPH!!!!! and that's NOT the scale speed.......ouch!!!!

Here's how I found out the speed:

Motor rpm/gear ratio= wheel rpm
wheel rpm x wheel circumference=distance per minute(cm)
distance per min in cm / 2.54 = inches per min
inches per min/12= feet per min
feet per min x 60 = feet per hour
feet per hour / 5,280= actual miles per hour
actual mph x 64 ( I did this for zipzaps) scale mph

sweet, no???
