will this be beter than the stock esc (will it be dig. prop.?) also has anyone figured out a way to make the motor stronger or a replacement cause it dont got enough juice to spin the tires going up a hill. maybe more batts or something

It will be proportional and overkill, a micro servo should do fine.

by overkill does that mean that it will burn up the motor?

I mean that it could handle a much bigger motor no problem. It would be like using a super rooster in a mini t.

oh sweet. so do you know exactly how to do it, like what kind of resistors i will need and where to solder them?

Unsolder the motor and solder some wires where the motor terminals were connected to the board for motor leads. Then turn your potentiometer all the way to one side and measure the resistance, halve that and find two resitors that value. One of each resistor lead goes to where the middle pot lead went and the other two go to where the other pot leads went to. You will need regular film resistors that you can pick up at radioshack.

wow that is really confusing, to me anyway. but what would happen if i just took the servo apart and hooked it up like it is?
