Brushed motor wiring questions

[lincpimp]

Thanks Chris, I thought I had it right but wanted to make sure. I just found some johnson 550 motors, so I may try them out and see how they do before I drop a bunch of money on the 700 motors. I am cheap sometimes...

If I wired the motors in series they would only go half as fast as they would wired parallel. This may be better as I am going for slow speed with good throttle control. 20mph in 2nd gear is plenty for this project.

Does anyone have any idea what kv the traxxas titan 23 motors are?? I figured they are around 1500kv, but not sure.

Or would it be better to wire them in parallel and just vary the input voltage? I will be using a pair of 2s packs, and can wire them in series or parallel.
