Is the Sprint the $99 one thats RTR? Maybe thats the Dash....not sure but I have a old Revolution Racing motor that I want to put in a cheap lil electric on road for the parking lot in front of my apartment.The motor has to be around 15 yrs old but its never been broken in and I think its a modified class so maybe that could go in a $100 car and be way overpowered compared to the 380 motor that it comes with.

good luck on the 4-Tec if ya get one.
