Building a trainer

[Tinbender]

THanks Oztruck and Espeefn, I truly plan to "dig in". I guess the first questions I have is about the motor.

When I ordered the truck, the store said I would have to buy a 55T motor. Then the ladysaid I would have to buy "A motor". I get the kit and there is a motor in it. Is this motor not good enough for a stock build? Why did she reccomend a me getting a 55T motor? I think it is 55T. I don't know the difference from one to another or how to look ast them and know what I have i my hand.
